41 | } 42 | } 43 | ``` 44 | 45 | 在創建一個類我的手機: 46 | 47 | 他只能承受110V的電壓 48 | 49 | 超過就爆炸了!! 50 | 51 | ```C# 52 | public class MyPhone 53 | { 54 | /// 55 | /// 對手機充電 56 | /// 57 | public void Fill_Cellphone(int power) { 58 | if (power==110) 59 | { 60 | Console.WriteLine("充電成功"); 61 | } 62 | else 63 | { 64 | Console.WriteLine("電壓太高!手機爆炸!"); 65 | } 66 | } 67 | } 68 | ``` 69 | 70 | 如果要充電怎麼辦? 71 | 72 | 這時我們的轉接頭發揮功用了 73 | 74 | 創建一個轉接頭的類別: 75 | 76 | ```C# 77 | public class PlugAdapter: IPlugin 78 | { 79 | private KoreaPlugin _plugin; 80 | /// 81 | /// 82 | /// 83 | /// 84 | public PlugAdapter(KoreaPlugin plugin) 85 | { 86 | _plugin = plugin; 87 | } 88 | 89 | public int Power() 90 | { 91 | return _plugin.Power()-110; 92 | } 93 | } 94 | ``` 95 | 96 | 在上面可以看到它 內部幫我們做了電壓轉換 (重要注意!!) 97 | 98 | 所以我們就可以進行充電了 99 | 100 | ```c# 101 | static void Main(string[] args) 102 | { 103 | #region 手機爆炸 104 | KoreaPlugin p = new KoreaPlugin();

154 | //實作硬碟讀取 155 | return result; 156 | } 157 | } 158 | ``` 159 | 160 | 日後需求增加可能從網路,資料庫其他來源讀取我們要的資料，所以我們開出一個 **Interface** 可以搭配[工廠模式](https://github.com/isdaniel/DesignPattern/tree/master/DesignPattern/SimpleFactory) 來掌控我們的產品 161 | 162 | ```c# 163 | public interface IReadData 164 | { 165 | string GetJsonData(string parameter); 166 | } 167 | ``` 168 | 169 | 新增的`WebReader`可以繼承此介面 170 | 171 | ```c# 172 | /// 173 | /// 從網路上讀取要的資料 174 | /// 175 | public class WebReader : IReadData 176 | { 177 | public string GetJsonData(string parameter) 178 | { 179 | string result = string.Empty; 180 | //實作網路讀取 181 | return result; 182 | } 183 | } 184 | ``` 185 | 186 | 但如果想讓舊有的`FileReader`也共享此介面怎麼處理呢? 187 | 188 | 這時可以考慮使用`Adapter` 來做銜接處理 189 | 190 | ```c# 191 | public class FileAdapter : IReadData 192 | { 193 | public string GetJsonData(string parameter) 194 | { 195 | var reader = new FileReader(); 196 | return reader.Read(parameter); 197 | } 198 | } 199 | ``` 200 | 201 | 建立一個`FileAdapter`並實現`IReadData`裡的方法，我們可以看到裡面我們一樣是使用`FileReader`，但外部的看到的介面已經不一樣了. 202 | 203 | 我們就可以讓`WebReader`和`FileAdapter` 達成相同介面. 204 | 205 | 206 | -------------------------------------------------------------------------------- /DesignPattern/AdpterPattern/WebReader.cs: -------------------------------------------------------------------------------- 1 | namespace AdapterPattern 2 | { 3 | /// 4 | /// 從網路上讀取要的資料 5 | /// 6 | public class WebReader : IReadData 7 | { 8 | public string GetJsonData(string parameter) 9 | { 10 | string result = string.Empty;

67 | } 68 | ``` 69 | 70 | 這邊我只介紹一種顏色和包包來當作範例,因為其他概念都一樣 71 | 72 | ```c# 73 | public class AdidasBag : BagBase 74 | { 75 | public AdidasBag(ColorBase color) : base(color) 76 | { 77 | } 78 | 79 | public override void GetBag() 80 | { 81 | Console.WriteLine($"It is Addidas Bag,Color is {color.Color()}");

這種情境很適合來使用 [`裝飾者模式`] 21 | 22 | 裝飾者模式 有兩個主要腳色 **被裝飾物件(Decorated)** & **裝飾物件(Decorator)** 23 | 24 | **被裝飾物件(Decorated)** 就像蛋糕的一樣, **裝飾物件(Decorator)**就是上的水果,奶油,巧克力...等等裝飾物品 25 | 26 | 一般先有蛋糕被裝飾物件(Decorated),後再將裝飾物品加上去裝飾物件(Decorator) 27 | 28 | **被裝飾物件(Decorated)** 如下圖 蛋糕的原型 29 | 30 | 31 | 32 | ![Alt

SetDecorated(IProcess process) 68 | { 69 | _process = process; 70 | } 71 | } 72 | 73 | 有兩點特別說明 74 | 75 | 1. protected IProcess _process; 儲存被裝飾的物件 76 | 2. 由 SetDecorated 方法來設置被裝飾的物件 77 | 78 | > 像俄羅斯娃娃只包裹一個娃娃,不管被包裹娃娃之前包含哪些娃娃 79 | 80 | ----- 81 | 82 | ## 第二步 創建被裝飾物品(Decorated) 83 | 84 | 因為是檔案我們直接使用 85 | 86 | 1. `File.ReadAllBytes` **讀** 檔案 87 | 2. `File.WriteAllBytes` **寫** 檔案 88 | 89 | /// 90 | /// 讀取檔案 91 | /// 92 | public class FileProcess : IProcess 93 | { 94 | public byte[] Read(string path) 95 | { 96 | return File.ReadAllBytes(path); 97 | } 98 | 99 | public void Write(string writePath, byte[] buffer) 100 | { 101 | File.WriteAllBytes(writePath, buffer); 102 | } 103 | } 104 | 105 | ----- 106 | 107 | ## 第三步 創建裝飾物品(Decorator) 108 | 109 | 這次主要裝飾物品有兩個 110 | 111 | * 加壓解壓ZIP檔 112 | * 加解密 113 | 114 | 115 | 加密裝飾器繼承`ProcessBase`並按照加解密重寫 `Write` ​和 `read` 方法 116 | 117 | /// 118 | /// Aes 加密裝飾器 119 | /// 120 | public class AESCrypProcess : ProcessBase 121 | { 122 | private AesCryptoServiceProvider aes; 123 | 124 | public string AESKey { get; set; } = "1776D8E110124E75"; 125 | public string AESIV { get; set; } = "B890E7F6BA01C273"; 126 | 127 | public AESCrypProcess() 128 | { 129 | aes = new AesCryptoServiceProvider(); 130 | aes.Key = Encoding.UTF8.GetBytes(AESKey); 131 | aes.IV = Encoding.UTF8.GetBytes(AESIV); 132 | } 133 | 134 | public override byte[] Read(string path) 135 | { 136 | byte[] encryptBytes = _process.Read(path); 137 | return DecryptData(encryptBytes); 138 | } 139 | 140 | /// 141 | /// 進行解密 142 | /// 143 | /// 144 | /// 145 | private byte[] DecryptData(byte[] encryptBytes) 146 | { 147 | byte[] outputBytes = null; 148 | using (MemoryStream memoryStream = new MemoryStream(encryptBytes)) 149 | { 150 | using (CryptoStream decryptStream = new CryptoStream(memoryStream, aes.CreateDecryptor(), CryptoStreamMode.Read)) 151 | { 152 | MemoryStream outputStream = new MemoryStream(); 153 | decryptStream.CopyTo(outputStream); 154 | outputBytes = outputStream.ToArray(); 155 | } 156 | } 157 | return outputBytes; 158 | } 159 | 160 | /// 161 | /// 裝飾者呼叫方法 162 | /// 163 | /// 164 | /// 165 | public override void Write(string path, byte[] data) 166 | { 167 | byte[] outputBytes = EncryptData(data); 168 | _process.Write(path, outputBytes); 169 | } 170 | 171 | private byte[] EncryptData(byte[] data) 172 | { 173 | byte[] outputBytes = null; 174 | using (MemoryStream memoryStream = new MemoryStream()) 175 | { 176 | using (CryptoStream encryptStream = new CryptoStream(memoryStream, aes.CreateEncryptor(), CryptoStreamMode.Write)) 177 | { 178 | MemoryStream inputStream = new MemoryStream(data); 179 | inputStream.CopyTo(encryptStream); 180 | encryptStream.FlushFinalBlock(); 181 | outputBytes = memoryStream.ToArray(); 182 | } 183 | } 184 | 185 | return outputBytes; 186 | } 187 | } 188 | 189 | 上面就把我們要用的裝飾物品 (備料) 準備完成 190 | 191 | ----- 192 | 193 | ## 第四步 創建使用(開始擺盤) 194 | 195 | 196 | 創建一個 DecorateFactory 來當生產 裝飾產品的工廠 197 | 198 | 建構子傳入一個 被裝飾的物件(`FileProcess`) 之後可依照喜好一直疊加 裝飾物品(`ZipProcess,AESCrypProcess...`) 199 | 200 | 201 | public class DecorateFactory 202 | { 203 | IProcess _original; 204 | 205 | public DecorateFactory(IProcess original) 206 | { 207 | _original = original; 208 | } 209 | 210 | public DecorateFactory SetProcess(ProcessBase process) 211 | { 212 | process.SetDecorated(_original); 213 | _original = process; 214 | return this; 215 | } 216 | 217 | public IProcess GetProcess() 218 | { 219 | return _original; 220 | } 221 | } 222 | 裝飾者模式順序是很重要的一個流程 223 | 224 | 225 | 為了方便讀者閱讀 我使用小畫家畫出 讀寫順序 226 | 227 | 如下圖 228 | 229 | ![Alt text](https://raw.githubusercontent.com/isdaniel/DesignPattern/master/DesignPattern/img/Decorator/decorator.png "Optional title") 230 | 231 | 232 | 使用就可很清晰來用 233 | 234 | 利用 `DecorateFactory`來創建裝飾流程 235 | 使用 `factroy.GetProcess();` 方法取得完成後的產品 236 | 在簡單呼叫讀和寫方法 237 | 238 | string filePath = @"C:\Users\daniel.shih\Desktop\test.zip"; 239 | string content = $"你好 123456 12@()!@ {Environment.NewLine} fsfd嘻嘻哈哈!!"; 240 | 241 | //設置初始化的被裝飾者 242 | DecorateFactory factroy = new DecorateFactory(new FileProcess()); 243 | 244 | //設置裝飾的順序 245 | factroy.SetProcess(new AESCrypProcess()) 246 | .SetProcess(new ZipProcess() { FileName = "1.txt",PassWord ="1234567"}); 247 | 248 | IProcess process = factroy.GetProcess(); 249 | 250 | byte[] data_buffer = Encoding.UTF8.GetBytes(content); 251 | process.Write(filePath, data_buffer); 252 | 253 | byte[] buffer = process.Read(filePath); 254 | Console.WriteLine(Encoding.UTF8.GetString(buffer)); 255 | 256 | 日後不管需求是改成 257 | 258 | * 文字內容->壓縮zip(附上密碼)->輸出儲存 259 | * 文字內容->AES加密->輸出儲存 260 | * 文字內容->AES加密->Zip檔附加密碼->輸出儲存 261 | 262 | 還是..... 263 | 264 | 我們都不怕 因為我們把各種操作封裝和多態 265 | 266 | 各個模組間都是獨立的很好映證 高內聚低耦合 的設計原則 267 | 268 | 269 | ## 小結: 270 | 271 | 裝飾者模式是一個很精美且優雅的模式 希望這篇文章可讓讀者對於此模式有更加了解 -------------------------------------------------------------------------------- /DesignPattern/DesignPattern.sln:

16 | 17 | 這就是我們這次的核心中介者 18 | 19 | ----- 20 | 21 | ## 中介者模式有幾個角色 22 | 23 | * AbstractMediator (抽像中介者)：定義中介者和各個同事者之間的通信的介面 24 | * ConcreteMediator (中介者)：知道每個同事物件，實現抽像中介者，負責協調和各個具體的同事的交互關係 25 | * AbstractColleague (抽象同事者)：定義同事者和中介者通信的接口 26 | * ConcreteColleague (同事者)：實現自己的業務，並且實現抽象方法，跟中介者進行通信 27 | 中介者模式特點是 28 | 29 | 中介者知道所有同事者物件，但同事者互相不知道對方存在需透過中介者傳遞訊息 30 | 如何傳遞和通知各個同事者由中介者內部決定 31 | 在裡面第二點是很重要的目標，把傳遞訊息的邏輯封裝在中介者裡面 32 | 33 | 程式碼 34 | 35 | public class ProductManager 36 | { 37 | public DBAdmin DbAdmin { get; set; } 38 | public Programer Programer { get; set; } 39 | 40 | internal void Send(string message, OriginReqBase req) 41 | { 42 | 　　　　　　 //如果是DBAdmin傳遞訊息由Programer執行,反之 43 | if (req.GetType() == typeof(DBAdmin)) 44 | Programer.DoProcess(message); 45 | else if(req.GetType() == typeof(Programer)) 46 | DbAdmin.DoProcess(message); 47 | } 48 | } 49 | 50 | 傳遞通知或訊息邏輯寫在`Send` 方法裡面. 51 | 52 | 本次範例依照傳入的型別,如果是`DBAdmin`傳遞訊息由`Programer`執行,反之 53 | 54 | public abstract class OriginReqBase 55 | { 56 | protected ProductManager _productManager; 57 | 58 | protected OriginReqBase(ProductManager productManager) 59 | { 60 | _productManager = productManager; 61 | } 62 | 63 | public virtual void Requirement(string message) 64 | { 65 | _productManager.Send(message, this); 66 | } 67 | } 68 | 69 | `OriginReqBase`(抽象同事者) 因為每個角色 `ConcreteColleague` 都需要知道中介者存在，所以把參數設定在建構子上。 70 | 71 | `Requirement` 方法通知 `PM` 中介者將資料傳遞出去 72 | 73 | public class Programer : OriginReqBase 74 | { 75 | 76 | public void DoProcess(string message) 77 | { 78 | Console.WriteLine($"Programer: {message}"); 79 | } 80 | 81 | public Programer(ProductManager productManager) : base(productManager) 82 | { 83 | } 84 | } 85 | 86 | public class DBAdmin : OriginReqBase 87 | { 88 | 89 | public void DoProcess(string message) 90 | { 91 | Console.WriteLine($"DBA:{message}"); 92 | } 93 | 94 | public DBAdmin(ProductManager productManager) : base(productManager) 95 | { 96 | } 97 | } 98 | DoProcess 方法 PM 中介者呼叫使用 99 | 100 | ProductManager pm = new ProductManager(); 101 | 102 | DBAdmin DBA1 = new DBAdmin(pm);　//DBA知道PM存在 103 | Programer RD1 = new Programer(pm);　//RD知道PM存在 104 | 105 | pm.Programer = RD1; //PM知道DBA 106 | pm.DbAdmin = DBA1; //PM知道RD 107 | 108 | //現在DBA和RD只需要傳訊息就可將訊息轉到需要知道的人 109 | 110 | RD1.Requirement("DB modify Requestment."); 111 | DBA1.Requirement("DB Process doing."); 112 | 113 | 有三大重點 114 | 115 | 1. `DBA`和`RD`(同事者) 知道`PM`(中介者)存在 116 | 2. `PM`(中介者)知道`DBA`和`RD`(同事者)存在 117 | 3. `DBA`和`RD`不用知道對方存在但卻可以互相傳遞訊息(因為PM已經幫助我們解耦合了) 118 | 119 | ![Alt

我看來這個解耦合核心思想跟容器有點像，因為需要做溝通或通知時我們統一只需要轉交給中介者會幫助我們處理溝通事宜 124 | 125 | ## 小結 126 | 127 | 在CQRS架構中介者模式很好幫助我們傳送命令間的解耦合,有機會在跟大家分享[MediatR](https://github.com/jbogard/MediatR)這個框架 128 |

(IPaymentService) 95 | new NullPayment() 96 | : new PaymentService(); 97 | return paymentService.calculate(model); 98 | } 99 | } 100 | ``` 101 | 102 | ## NullObject Pattern缺點: 103 | 104 | 如果團隊工程師不知道目前程式碼已經存在NullObject實作，會寫出多餘的null測試. 105 | 如果目前系統只是需要少量對於null做判斷，這時導入NullObject會導致程式碼變得複雜. 106 | 107 | ## 小結: 108 | 109 | 假如系統中有許多地方需要判斷null並處理相對應的動作就很適合使用`NullObject` Pattern，但如果判斷null地方不是很多還是判斷就好了 110 | 111 | [程式碼範例](https://github.com/isdaniel/DesignPattern/tree/master/DesignPattern/NullObjectPattern) -------------------------------------------------------------------------------- /DesignPattern/ObserverPattern/App.config: -------------------------------------------------------------------------------- 1 |  2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | -------------------------------------------------------------------------------- /DesignPattern/ObserverPattern/IObserveable.cs: -------------------------------------------------------------------------------- 1 | using System;

42 | } 43 | ``` 44 | 45 | > 如果沒使用動態代理會怎麼來寫Log呢? 46 | 47 | ```c# 48 | /// 49 | /// 檢查用戶是否合法 50 | /// 51 | /// 52 | public bool IsUserAuth(UserModel user) 53 | { 54 | Console.WriteLine($"使用者登入：帳號={user.UserName} 密碼={user.Password}"); 55 | return userList.GetAllUser() 56 | .Any(o => user.UserName == o.UserName && user.Password == o.Password); 57 | } 58 | ``` 59 | 60 | （已Console.WriteLine來代替寫log的程式碼) 61 | 在執行前後寫上Log，但這樣讓程式碼可讀性變差了點，因為Log和檢查使用者是否登入完全沒關係! 62 | 63 | 那我們要怎麼做才可讓程式碼Clear一點呢? 64 | 在下面我會介紹靜態代理模式，來解決上面的問題 65 | 66 | ---- 67 | 68 | ## 利用.NET實現靜態代理 69 | 70 | 我們先理解業務在哪邊，業務在下面紅框的部分 `Console.log` 只是記錄此次驗證的資料 71 | 72 | > 我們可以主要邏輯提取動作來做一個簽章 73 | 74 | ![img](https://az787680.vo.msecnd.net/user/%E4%B9%9D%E6%A1%83/17bcea05-79ca-46d6-8893-d1c4ae124d4f/1507791353_49889.png) 75 | 76 | > 在我心中**介面代表能力，抽象類別代表這一類事物** 77 | 78 | 因為在此次需求驗證是一種能力，所以我提出來成一個介面 79 | 80 | ```c# 81 | public interface ISubject 82 | { 83 | bool IsAuth(UserModel user); 84 | } 85 | ``` 86 | 87 | 有兩個類別 `LogicProxyService`和`Logicservice`都實現 `ISubject` 88 | 因為不管是代理類別和被代理類別都擁有檢核能力 89 | 90 | 我們就可將主要邏輯寫在`Logicservice ` 91 | 92 | ```c# 93 | public class Logicservice : ISubject 94 | { 95 | MockUserData userList = new MockUserData();

121 | return _realSubjcet.IsAuth(user); 122 | } 123 | } 124 | ``` 125 | 126 | 在外界只需這樣使用 127 | 128 | 傳入被代理物件 129 | 使用代理物件呼叫方法 130 | 131 | ```c# 132 | #region StaticProxy 133 | var testUser = new UserModel() { Password = "1234", RowID = 1, UserName = "test" }; 134 | LogicProxyService staticProxy = new LogicProxyService(new Logicservice()); 135 | staticProxy.IsAuth(testUser); 136 | #endregion 137 | ``` 138 | 139 | 這樣程式碼就比上一篇乾淨許多了！ 寫日誌的程式碼和主要邏輯分離開來 140 | 141 | 靜態代理最主要是將核心邏輯和非核心邏輯分割開來，讓程式碼保持乾淨 142 | 143 | 144 | 但靜態代理還是有個缺點，如我們需要擴充100個代理方法 我需要撰寫100代理類別 145 | 146 | 實在有夠累.... 147 | 148 | 但別擔心在下面會介紹**[動態代理模式]**來解決此問題 149 | 150 | ---- 151 | 152 | ## 利用.NET實現動態代理 153 | 154 | 靜態代理可以將執行邏輯和寫日誌這兩個動作分離乾淨 155 | 156 | Q：但又衍生一個問題是我們有一大堆代理類別要寫，這樣好不方便 157 | 158 | A：如果可以攔截或獲取方法實行的瞬間並在執行前後加上我們寫日誌的動作該有多好 159 | 160 | 聰明的.Net框架 已經幫我們處理上面問題了(不然我們要動態產生一堆程式碼和動態編譯他們...這會累屎人QQ) 161 | 162 | > 何謂動態代理? 163 | 164 | 簡單來說就是 165 | 166 | > 這個代理類別在Runtime期間由程式動態幫我們生產 167 | 168 | 我簡單來使用 [.Net RealProxy](https://docs.microsoft.com/zh-tw/dotnet/api/system.runtime.remoting.proxies.realproxy?redirectedfrom=MSDN&view=netframework-4.7.2) 類別來實作，[透明動態代理] 169 | 170 | 要被RealProxy代理類別要符合以下一種情況 171 | 172 | 1. 介面 173 | 2. 繼承於`MarshalByRefObject` 174 | 175 | 廢話不多說先附上程式碼 176 | 177 | ```c# 178 | public class DynamicProxy : RealProxy 179 | where T : MarshalByRefObject 180 | { 181 | private MarshalByRefObject _target; 182 | 183 | public DynamicProxy(T target) : base(typeof(T)) 184 | { 185 | } 186 | 187 | /// 188 | /// 動態攔截方法實作的瞬間 189 | /// 190 | /// 191 | /// 192 | public override IMessage Invoke(IMessage msg) 193 | { 194 | IMethodCallMessage callMethod = msg as IMethodCallMessage; 195 | MethodInfo targetMethod = callMethod.MethodBase as MethodInfo; 196 | IMethodReturnMessage returnMethod = null; 197 | //得到方法上面的標籤 攔截要執行非核心邏輯的動作 198 | var attrs = Attribute.GetCustomAttributes(targetMethod, typeof(AopBaseAttribute)) as AopBaseAttribute[]; 199 | try 200 | { 201 | foreach (var attr in attrs) 202 | { 203 | //執行方法前的動作 204 | attr.Excuting(callMethod.Args); 205 | } 206 | //執行方法 207 | var result = targetMethod.Invoke(_target, callMethod.Args); 208 | returnMethod = new ReturnMessage(result, 209 | callMethod.Args, 210 | callMethod.Args.Length, 211 | callMethod.LogicalCallContext, 212 | callMethod); 213 | foreach (var attr in attrs) 214 | { 215 | //執行方法後動作 216 | attr.Excuted(result); 217 | } 218 | } 219 | catch (Exception ex) 220 | { 221 | returnMethod = new ReturnMessage(ex, callMethod); 222 | } 223 | return returnMethod; 224 | } 225 | } 226 | ``` 227 | 228 | 這是動態代理最核心的程式碼 229 | 230 | 繼承`RealProxy`類別並實作`IMessage`方法 231 | 232 | ```c# 233 | public override IMessage Invoke(IMessage msg) 234 | ``` 235 | 236 | 我們把上篇的靜態代理改成動態代理 237 | 238 | 首先我們為動態代理新增攔截點製作 `AopBaseAttribute` 239 | 為日後切面擴展程式的基礎 240 | 241 | ```c# 242 | public abstract class AopBaseAttribute : Attribute, IInterception 243 | { 244 | public virtual void Excuted(object result) 245 | { 246 | } 247 | 248 | public virtual void Excuting(object[] args) 249 | { 250 | } 251 | } 252 | ``` 253 | 254 | 新增`LogAttribute` 作為寫日誌的切入點 255 | 256 | ```c# 257 | public class LogAttribute : AopBaseAttribute 258 | { 259 | public override void Excuting(object[] args) 260 | { 261 | var user = args.FirstOrDefault() as UserModel; 262 | if (user != null) 263 | { 264 | Console.WriteLine($"DynamicProxy 使用者登入：帳號={user.UserName} 密碼={user.Password}"); 265 | } 266 | Console.WriteLine(); 267 | } 268 | } 269 | ``` 270 | 271 | 邏輯類別那邊繼承 `MarshalByRefObject` 並將剛剛做的 Log標籤(`Attirbute`) 放在方法上 272 | 273 | ```c# 274 | public class DLogicservice : MarshalByRefObject 275 | { 276 | private MockUserData userList = new MockUserData(); 277 | 278 | [Log] 279 | public bool IsAuth(UserModel user) 280 | { 281 | return userList.GetAllUser() 282 | .Any(o => user.UserName == o.UserName && user.Password == o.Password); 283 | } 284 | } 285 | ``` 286 | 287 | 調用時只需要這樣 288 | 289 | ```c# 290 | //產生代理類別 291 | var proxy = new DynamicProxy(new DLogicservice()); 292 | //取得代理類別實體 293 | var obj = proxy.GetTransparentProxy() as DLogicservice; 294 | //呼叫方法 295 | obj.IsAuth(testUser); 296 | ``` 297 | 298 | 另外小弟有參考ASP.Net原始碼來製作動態的攔截器框架 [AwesomeProxy.Net](https://github.com/isdaniel/AwesomeProxy.Net) ，放在github上面歡迎大家討論 -------------------------------------------------------------------------------- /DesignPattern/ProxyPattern/StaticProxy/ISubject.cs: -------------------------------------------------------------------------------- 1 | using System;

108 | public abstract string Running(Product p); 109 | 110 | public abstract string SetSatus(PayStatus s); 111 | } 112 | ``` 113 | 114 | `PaymentGate` 是給外部呼叫端使用的類別,我們可比較上面之前`PaymentContext`類別可看到`if....else` 全部不見了, 115 | 116 | 因為狀態封裝到各個類別中了 117 | 118 | ```c# 119 | public class PaymentGate 120 | { 121 | Product _product; 122 | 123 | internal PaymentSatusBase CurrnetProceess { get; set; } // 這裡擁有下個流程的引用 124 | 125 | public PaymentGate(Product p) 126 | { 127 | _product = p; 128 | CurrnetProceess = new InitSatus(this); 129 | } 130 | 131 | internal PayStatus CurrnetStatus { get; set; } 132 | 133 | /// 134 | /// 設置狀態 135 | /// 136 | /// 137 | public string SetStatus(PayStatus status) 138 | { 139 | return CurrnetProceess.SetSatus(status); 140 | } 141 | 142 | /// 143 | /// 跑流程 144 | /// 145 | /// 146 | public string RunProcess() 147 | { 148 | return CurrnetProceess.Running(_product); 149 | } 150 | } 151 | ``` 152 | 153 | 如何新建一個流程物件? 154 | 首先我們需要先取得當前使用者使用的 `PaymentGate` 引用並傳入建構子當作參數 155 | 實現`Running`和`SetStatus`方法,並將此狀態的邏輯寫上 156 | 執行完後需要更改下個流程,可以將值賦予給`CurrnetProceess` 屬性 157 | 158 | ```c# 159 | public class ProcessSatus : PaymentSatusBase 160 | { 161 | public ProcessSatus(PaymentGate g) 162 | { 163 | _gate = g; 164 | } 165 | public override string Running(Product p) 166 | { 167 | string result = "交易中請稍後"; 168 | 169 | if (p.Price > 300) 170 | { 171 | result = "物件超過300元 交易取消中"; 172 | _gate.CurrnetProceess = new CancelSatus(_gate); 173 | } 174 | else 175 | _gate.CurrnetProceess = new SuccessSatus(_gate); 176 | 177 | return result; 178 | } 179 | 180 | public override string SetSatus(PayStatus s) 181 | { 182 | string result = string.Empty; 183 | if (s == PayStatus.Init) 184 | result = "請勿重新建立訂單"; 185 | return result; 186 | } 187 | } 188 | ``` 189 | 190 | 說明: 191 | 192 | 以流程進行中為例子. 193 | 194 | 他會判斷商品使用超過300元,來決定下個流程 所以我們就把這個邏輯寫在此類中. 195 | 196 | 另外後面幾個流程比照辦理全部搬入類別中 197 | 198 | ```c# 199 | public class CancelSatus : PaymentSatusBase 200 | { 201 | public CancelSatus(PaymentGate g) 202 | { 203 | _gate = g; 204 | } 205 | public override string Running(Product p) 206 | { 207 | return "交易取消完成"; 208 | } 209 | 210 | public override string SetSatus(PayStatus s) 211 | { 212 | string result = string.Empty; 213 | if (s == PayStatus.Init) 214 | result = "訂單取消請勿修改"; 215 | return result; 216 | } 217 | } 218 | 219 | 220 | public class SuccessSatus : PaymentSatusBase 221 | { 222 | public SuccessSatus(PaymentGate g) 223 | { 224 | _gate = g; 225 | } 226 | 227 | public override string Running(Product p) 228 | { 229 | return "交易完成"; 230 | } 231 | 232 | public override string SetSatus(PayStatus s) 233 | { 234 | string result = string.Empty; 235 | if (s == PayStatus.Init) 236 | result = "訂單成功請勿修改"; 237 | return result; 238 | } 239 | } 240 | ``` 241 | 242 | 最後外部程式使用如下 243 | 244 | ```c# 245 | Product p = new Product(); 246 | p.Name = "電腦"; 247 | p.Price = 300000; 248 | 249 | PaymentGate context = new PaymentGate(p); 250 | Console.WriteLine(context.RunProcess()); 251 | Console.WriteLine(context.RunProcess()); 252 | Console.WriteLine(context.RunProcess());

SetUpClass (每個測試類別只都執行一次) 35 | 2. SetUpUnitTest (每次執行測試方法時都執行一次) 36 | 3. UnitTest (執行測試方法) 37 | 38 | 39 | **如下圖** 40 | 41 | ![Alt text](https://www.codeproject.com/KB/cs/autp1/testSuiteFlow.jpg "Optional title") 42 | 43 | (圖片來自網路上) 44 | 45 | ----- 46 | 47 | 範例： 48 | 49 | 此範例使用Console來模擬單元測試框架流程： 50 | 51 | 建立一個 `UnitFlowBase` 抽像類別，裡面有三個方法 52 | 53 | 1. SetUpClass (每個測試類別只都執行一次) 54 | 2. SetUpUnitTest (每次執行測試方法時都執行一次) 55 | 3. UnitTest (執行測試方法) 56 | 57 | 此抽象類別提供3個Hock讓子類實做細節。 58 | `UnitFlowBase`只提供框架 59 | 60 | ```c# 61 | public abstract class UnitFlowBase 62 | { 63 | protected UnitFlowBase() 64 | { 65 | SetUpClass(); 66 | } 67 | 68 | protected virtual void SetUpClass() 69 | { 70 | } 71 | 72 | protected virtual void SetUpUnitTest() 73 | { 74 | } 75 | 76 | protected abstract bool Execute(); 77 | 78 | public void UnitTest() 79 | { 80 | SetUpUnitTest(); 81 | Console.WriteLine(Execute() ? "Assert Successful." : "Assert Fail."); 82 | } 83 | } 84 | ``` 85 | 86 | 建立另一個類別`UnitCounter` 實現那三個方法 87 | 特別是`Execute`方法 我顯示目前 `ClassCount` 跟 `MethodCount` 執行次數 88 | 89 | ```C# 90 | public class UnitCounter : UnitFlowBase 91 | { 92 | private int _classCounter = 0; 93 | 94 | private int _methodCounter = 0; 95 | 96 | protected override void SetUpClass() 97 | { 98 | _classCounter++; 99 | } 100 | 101 | protected override void SetUpUnitTest() 102 | { 103 | _methodCounter++; 104 | } 105 | 106 | protected override bool Execute() 107 | { 108 | Console.WriteLine($"ClassCounter : {_classCounter}"); 109 | Console.WriteLine($"MethodCounter: { _methodCounter}"); 110 | 111 | return true; 112 | } 113 | } 114 | ``` 115 | 116 | 呼叫實我們建立一個`UnitCounter`類別，但執行三次`UnitTest`方法 117 | 118 | ```C# 119 | class Program 120 | { 121 | static void Main(string[] args) 122 | { 123 | UnitCounter unitMock = new UnitCounter(); 124 | unitMock.UnitTest(); 125 | unitMock.UnitTest(); 126 | unitMock.UnitTest(); 127 | 128 | Console.ReadKey(); 129 | } 130 | } 131 | ``` 132 | 133 | 執行結果如下圖： 134 | 135 | ![img](../img/TemplateMethod/TemplateMethod.PNG) 136 | 137 | 雖然執行3次 `UnitTest` 方法 但 `ClassCounter` 值卻一直是1而 `MethodCounter` 會依照執行幾次就加幾次. 138 | 139 | ------ 140 | 141 | # 小結: 142 | 143 | 日後測試程式只需關注我們需要如何實現邏輯細解（重寫三個方法），核心流程順序就交由`UnitFlowBase`決定。 144 | -------------------------------------------------------------------------------- /DesignPattern/TemplatePattern/TemplatePattern.csproj: -------------------------------------------------------------------------------- 1 |  2 | 3 | 4 | 5 | Debug 6 | AnyCPU 7 | {10392CBE-21FF-45DA-A1B1-5F71E356740F} 8 | Exe 9 | Properties 10 | TemplatePattern 11 | TemplatePattern 12 | v4.5.2 13 | 512 14 | true 15 | 16 | 17 | 18 | AnyCPU 19 | true 20 | full 21 | false 22 | bin\Debug\ 23 | DEBUG;TRACE 24 | prompt 25 | 4 26 | 27 | 28 | AnyCPU 29 | pdbonly 30 | true 31 | bin\Release\ 32 | TRACE 33 | prompt 34 | 4 35 | 36 | 37 | 38 | 39 | 40 | 41 | 42 | 43 | 44 | 45 | 46 | 47 | 48 | 49 | 50 | 57 | -------------------------------------------------------------------------------- /DesignPattern/TemplatePattern/UnitCounter.cs: -------------------------------------------------------------------------------- 1 | using System; 2 | 3 | namespace TemplatePattern 4 | { 5 | public class UnitCounter : UnitFlowBase 6 | { 7 | protected override void SetUp() 8 | { 9 | Console.WriteLine("Set up UnitCounter thing."); 10 | } 11 | 12 | protected override void OneTimeSetUp() 13 | { 14 | Console.WriteLine("OneTimeSetUp!!"); 15 | } 16 | } 17 | } -------------------------------------------------------------------------------- /DesignPattern/TemplatePattern/UnitFlowBase.cs: -------------------------------------------------------------------------------- 1 | using System; 2 | using System.Collections.Generic; 3 | 4 | namespace TemplatePattern 5 | { 6 | public abstract class UnitFlowBase 7 | { 8 | protected virtual void OneTimeSetUp() 9 | { 10 | } 11 | 12 | protected virtual void Dispose() 13 | { 14 | } 15 | 16 | protected virtual void SetUp() 17 | { 18 | } 19 | 20 | protected virtual void TearDown() 21 | { 22 | } 23 | 24 | public void UnitTest(IEnumerable> testCases) 25 | { 26 | OneTimeSetUp(); 27 | foreach (var testCase in testCases) 28 | { 29 | SetUp(); 30 | Console.WriteLine(testCase() ?
