1.1///先声明一个单列集合
    
      public List<SE> list = new List<SE>();
    
    1.2///初始化三个对象
    
      private void FrmMain_Load(object sender, EventArgs e)
            {
    
                    SE s1 = new SE();
                    s1.id = 20161000;
                    s1.name = "张三";
                    s1.age = 20;
                    s1.gender = "男";
    
                    SE s2 = new SE();
                    s2.id = 20161002;
                    s2.name = "李四";
                    s2.age = 18;
                    s2.gender = "男";
    
                    SE s3 = new SE();
                    s3.id = 20161004;
                    s3.name = "凤姐";
                    s3.age = 20;
                    s3.gender = "女";
    
    1.3//把数据添加到集合中并用dgvList加载出来
    
                    list.Add(s1);
                    list.Add(s2);
                    list.Add(s3);
