4 | How to use it is here:http://www.cnblogs.com/coldairarrow/p/7501645.html 5 | 6 | 如何使用？
7 | 框架核心类：
8 | SocketServer//Socket服务端
9 | SocketConnection//Socket连接对象,双向通信
10 | SocketClient//Socket客户端
11 | 1、建立连接
12 | 服务端：
13 | SocketServer server = new SocketServer(12345);//默认监听地址0.0.0.0 端口12345,构造函数重载可以修改
14 | server.StartServer();
15 | 客户端：
16 | SocketClient client = new SocketClient(12345);//默认连接地址127.0.0.1 端口12345，构造函数重载可以修改
17 | client.StartClient();
18 | 2、消息收发
19 | 服务端：
20 | 服务端主要就是维护一个客户端连接队列，每当新的客户端连接到服务端时，都会将新的连接对象添加到连接队列中。
21 | 因此，服务端要向客户端发送消息，必须先找到需要发送消息的连接对象。
22 | 那么才能如何找到需要发送消息的连接呢？
23 | 思路：当我们要寻找某些东西的时候，肯定需要某些东西的特征，比如说我们要确认一个人的身份，我们只需要知道这个人的身份证（黑的不算），那么我们就可以轻易的知道这个人的身份信息了。同样道理，我已经预先给SocketConnection开放了一个自定义属性Property,其类型为object，也就是说，你可以传字符串，也可以传自定义对象，这个Property就可以作为当前连接的身份标志了，当连接拥有身份标志之后，就可以通过Lambda表达式查询出来（不会的自己去补充基础），服务端调用GetConnectionList方法，传入筛选条件，即可找到符合条件的IEnumerable,也可以调用GetTheConnection方法，传入筛选条件，找到符合条件的一个SocketConnection，使用示例如下：
24 | var theConnection= server.GetTheConnection(x =>
25 | {
26 | var Id = (string)x.Property;
27 | return Id == "Admin";
28 | });
29 |
30 | 看代码吃力的，请补充基础
31 |
32 | 发送消息：
33 | theConnection.Send("Hello World!");//默认UTF-8编码格式发送字符串，有重载方法，不详解了
34 | 客户端：
35 | 发送消息:
36 | client.Send("OK!");//默认UTF-8编码格式发送字符串，有重载方法，不详解了
37 | 38 | 事件处理：
39 | 客户端连接到服务端之后，双方肯定要进行通信，也就是收发数据，这里我只讲最常用的事件
40 | 1、新的客户端连接到服务端时触发（可以选择这个时候给对应的SocketConnection传入身份标识Property）
41 | server.HandleNewClientConnected = new Action((theServer,theCon) =>
42 | {
43 | theCon.Property = "Admin";//身份标志，也可以传别的对象,自己定义，用的时候强制转下（不懂，百度：多态）
44 | Console.WriteLine($@"当前连接数：{theServer.GetConnectionCount()}");
45 | });
46 | 2、服务端接收到客户端发送的消息时触发
47 | //bytes为收到的数据（字节数组），client为对应的SocketConnection,theServer为维护连接的服务对象
48 | server.HandleRecMsg = new Action((bytes,client,theServer)=>
49 | { 50 | string msg = Encoding.UTF8.GetString(bytes);
51 | client.Send($"服务端已收到收到消息:{msg}");
52 | Console.WriteLine($"收到消息:{msg}");
53 | });
54 | 3、客户端端接收到客户端发送的消息时触发
55 | client.HandleRecMsg = new Action((bytes, theClient) =>
56 | {
57 | string msg = Encoding.UTF8.GetString(bytes);
58 | Console.WriteLine($"收到消息:{msg}");
59 | });
