set; } 14 | 15 | public string Name { get; set; } 16 | 17 | public string Psw { get; set; } 18 | } 19 | ``` 20 | ### 基本使用 21 | 22 | #### 插入 23 | ```c# 24 | using (SqlConnection cn = new SqlConnection(_connectionString)) 25 | { 26 | cn.Open(); 27 | User user = new User { Name = "波多野结衣" , Psw = "123"}; 28 | int id = cn.Insert(user); 29 | cn.Close(); 30 | } 31 | ``` 32 | #### 更新 33 | ``` 34 | using (SqlConnection cn = new SqlConnection(_connectionString)) 35 | { 36 | cn.Open(); 37 | int id = 1; 38 | User user = cn.Get(id); 39 | user.Name = "林志玲"; 40 | cn.Update(user); 41 | cn.Close(); 42 | } 43 | ``` 44 | #### 删除 45 | ```c# 46 | using (SqlConnection cn = new SqlConnection(_connectionString)) 47 | { 48 | cn.Open(); 49 | int id = 1; 50 | User user = cn.Get(id); 51 | cn.Delete(user); 52 | cn.Close(); 53 | } 54 | ``` 55 | #### 基于ID查询 56 | ```c# 57 | using (SqlConnection cn = new SqlConnection(_connectionString)) 58 | { 59 | cn.Open(); 60 | int Id = 1; 61 | Person person = cn.Get(Id); 62 | cn.Close(); 63 | } 64 | ``` 65 | #### 基于动态对象查询 66 | ```c# 67 | using (SqlConnection cn = new SqlConnection(_connectionString)) 68 | { 69 | cn.Open(); 70 | Person person = cn.GetList(new { Name = "波多野结衣" , Psw = "123"}); 71 | cn.Close(); 72 | } 73 | ``` 74 | #### 基于表达式查询 75 | ```c# 76 | using (SqlConnection cn = new SqlConnection(_connectionString)) 77 | { 78 | cn.Open(); 79 | Person person = cn.Get(u => u.Id != 1); 80 | person = cn.GetList(u => u.Name.Contains("1")); //Like查询 81 | person = cn.GetList(u => u.Name.StartsWith("1")); //Like查询 82 | person = cn.GetList(u => u.Name.EndsWith("1")); //Like查询 83 | 84 | List valueList = new List() { "1", "2", "3" }; 85 | person = cn.GetList(u => valueList.Contains(u.Name)); //in查询 86 | person = cn.GetList(u => !valueList.Contains(u.Name)); //not in查询 87 | 88 | person = cn.GetList(u => u.Id == 1 || (u.Id == 2 && u.Name.Contains("1"))); //复合查询 89 | cn.Close(); 90 | } 91 | ``` 92 | #### 基于Predicate查询 93 | ```c# 94 | using (SqlConnection cn = new SqlConnection(_connectionString)) 95 | { 96 | cn.Open(); 97 | var predicate = Predicates.Field(p => p.Name, Operator.Like, "李%"); 98 | IEnumerable list = cn.GetList(predicate); 99 | cn.Close(); 100 | } 101 | ``` 102 | ##### 构建查询条件（基于MySQL） 103 | * 简单查询，包括大于，等于，Like等，生成：(`User`.`Name` LIKE @Name_0) 104 | ```c# 105 | Predicates.Field(p => p.Name, Operator.Like, "李%"); 106 | ``` 107 | * in查询，生成：(`User`.`Name` IN (@Name_0, @Name_1, @Name_2)) 108 | ```c# 109 | List valueList = new List() { "1", "2", "3" }; 110 | Predicates.Field(p => p.Name, Operator.Eq, valueList); 111 | ``` 112 | * between查询，生成：(`User`.`Name` NOT BETWEEN @Name_0 AND @Name_1) 113 | ```c# 114 | Predicates.Between(p => p.Name, new BetweenValues { Value1 = 1, Value2 = 10 }, true); 115 | ``` 116 | * exist查询，生成：(NOT EXISTS (SELECT 1 FROM `User` WHERE (`User`.`Name` LIKE @Name_0))) 117 | ```c# 118 | IFieldPredicate nameFieldPredicate = Predicates.Field(p => p.Name, Operator.Like, "李%"); 119 | Predicates.Exists(nameFieldPredicate, true); 120 | ``` 121 | * 组合查询，生成：(((`User`.`Name` LIKE @Name_0) AND (`User`.`Name` NOT BETWEEN @Name_1 AND @Name_2)) OR (`User`.`Name` LIKE @Name_3)) 122 | ```c# 123 | IList predList = new List(); 124 | predList.Add(Predicates.Field(p => p.Name, Operator.Like, "李%")); 125 | predList.Add(Predicates.Field(p => p.Name, Operator.Eq, valueList)); 126 | IPredicateGroup predGroup1 = Predicates.Group(GroupOperator.And, predList.ToArray()); 127 | 128 | IList predList2 = new List(); 129 | predList2.Add(predGroup1); 130 | predList2.Add(Predicates.Field(p => p.Name, Operator.Like, "张%")); 131 | IPredicateGroup predGroup2 = Predicates.Group(GroupOperator.Or, predList2.ToArray());
