创建数组对象以及调用方法

 class Class1
    {
       public int dh;          //电话
       public String name;   //名称
        public int  mima;  //密码
        public String sfz;  //身份证
        public int yue;  //余额

 

    }
 
 
 
 
 对象
  Class1[] ss = new Class1[3];
            ss[0] = new Class1();   实例化数组0空间
            ss[0].dh = 1722222;
            ss[0].name = "胡";
            ss[0].mima = 1234;
            ss[0].sfz = "41161246187461";
            ss[0].yue = 6999;

 
            ss[1] = new Class1();    实例化数组1空间
            ss[1]. name = "安";
            ss[1].dh = 32132222;
            ss[1].mima = 1234;
            ss[1].sfz = "51161246187461";
            ss[1].yue = 61999;

            ss[2] = new Class1();  实例化数组元素2 空间
            ss[2].name = "民";
            ss[2].dh = 62132222;
            ss[2].mima = 1234;
            ss[2].sfz = "551161246187461";
            ss[2].yue = 21999;

            foreach (Class1 nn in ss)   遍历数组
            {          
                if (nn.name.Equals("胡"))  判断遍历数组有没有此元素
                {
                    Console.WriteLine("存在");
                }
                else
                {
                    Console.WriteLine("不纯在");
                }

            }
   
   也可以在类方法里创建对象并且赋值   上方法是在main方法里  赋值    一般情况都是在  类方法里
   便于修改
