C#结构体的使用结构体：相当于是我们自己定义的一种复杂的类型。常见简单类型：int...  double float bool char string 常见复杂类型：DateTime  数组类型生活中大部份的对象都是复合型的对象。如何定义结构体类型？一般来说结构体的定义要放在class的外面或class的里面，尽量不放在Main的里面。 struct 自定义类型名 {     public 变量类型  变量名;     ......;     ......;     ......;} 例如：     struct YuanGong  //自定义的数据类型。用来描述员工的信息。     {         public string NO;         public string Name;         public int Age;         public string Nation;         public bool Sex;     }如何用自定义的类型来定义变量？自定义类型名 变量 = new 自定义类型名();如何使用自定义类型的变量？ 变量.子变量 = "xxxx"; Console.WriteLine(变量名.子变量); 例如：             //定义自定义类型的变量             YuanGong zhangsan = new YuanGong();             //给变量赋值             zhangsan.NO = "Y001";             zhangsan.Name = "张三";             zhangsan.Age = 22;             zhangsan.Sex = true;             zhangsan.Nation = "汉族";             //对变量取值             Console.WriteLine(zhangsan.NO+"\t"+zhangsan.Name+"\t"+zhangsan.Age);
