C#程序定义结构图的方式如下:

public struct student  //结构体名
{
        //没有public 修饰的成员变量 不能被访问
	 public string Name;
         public string Sex;
	 public int Age;
         public  student(string name, string sex, int age)
         {
               this.Name = name;
               this.Sex = sex;
               this.Age = age;
          }          
}

如果结构体内定义了静态成员或者函数, 则调用时只会被初始化一次, 如:

static student()
{
             Console.WriteLine("我是静态函数");
} 

student boy1 = new Student("小明","男", 18); 
student boy2 = boy1;
