set; } 41 | 42 | [Column("name")] 43 | public string Name { get; set; } 44 | 45 | [Column("age")] 46 | public int Age { get; set; } 47 | 48 | [Column("school_id")] 49 | public string SchoolId { get; set; } 50 | 51 | [Column("birthday")] 52 | public long Birthday { get; set; } 53 | } 54 | ``` 55 | Table 标记一个表对象。如：[Table("t_student")] 代表 Student 类将映射为数据库表 t_student
Column 标记一个列对象。如：[Column("id")] 代表 Id 属性将映射为数据库列 id 56 | 57 | 58 | 59 | 60 | 创建数据库操作实例： 61 | 62 | > 参数方式创建，可设置连接池，默认开启连接池，连接池默认数量为3 63 | ```csharp 64 | IDbContext dbContext = new DbContext("127.0.0.1", "test", "root", "123456"); 65 | ``` 66 | 67 | 新增： 68 | ```csharp 69 | var result = dbContext.Insert(new Student() 70 | { 71 | Name = "zhangsan", 72 | Age = 18, 73 | SchoolId = "123" 74 | }); 75 | ``` 76 | > Insert 方法可插入一个对象，表示对 t_student 表插入一条数据。
最后被解释为 SQL 语句 ->
INSERT INTO t_student(id,name,age,school_id,birthday) VALUES(@id,@name,@age,@school_id,@birthday); 77 | 78 | 79 | 80 | 81 | 修改： 82 | ```csharp 83 | var result = dbContext.Update(x => x.Id.Contains("test_update_list"), new Student() { Age = 19 }); 84 | ``` 85 | > Update 方法表示更新操作。如：
参数1：x => x.Id.Contains("test_update_list") 被解释为 WHERE id LIKE '%test_update_list%'
参数2：new Student() { Age = 19 } 被解释为 SET age = @age
最终SQL语句为：
UPDATE t_student SET age = @age WHERE id LIKE '%test_update_list%'; 86 | 87 | 88 | 89 | 90 | 91 | 删除： 92 | ```csharp 93 | var result = dbContext.Delete(x => x.Age > 0); 94 | ``` 95 | > Delete 方法表示删除操作。最终被解释为 SQL 语句：
DELETE FROM t_student WHERE age > 0; 96 | 97 | 98 | 99 | 100 | 查询： 101 | ```csharp 102 | var list = dbContext.Query(x => x.Age == 19 103 | && x.Id.Contains("test_query_list")) 104 | .ToList(); 105 | ``` 106 | > Query => ToList 方法表示查询操作。最终被解释为 SQL 语句：
