using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace Ch01_1
{
    public partial class FrmMain : Form
    {
        public FrmMain()
        {
            InitializeComponent();

添加一个Students类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Ch01_1
{
   public  class Students
    {
        public string Name { set; get; }
        public string Sex { get; set; }
        public int Age { get; set; }
        public string Hobby { get; set; }

       public static List<Students> GetStudents()
        {
            List<Students> stus = new List<Students>
            {
                new Students() {Name="张三",Age=32,Sex="男",Hobby="聊天" },
                new Students() {Name="李四",Age=23,Sex="女",Hobby="玩游戏" },
                new Students() {Name="王五",Age=32,Sex="男",Hobby="打球" },
                new Students() {Name="张例是",Age=32,Sex="女",Hobby="小说" },
                new Students() {Name="发发",Age=32,Sex="男",Hobby="写代码" },
                new Students() {Name="梵蒂冈",Age=32,Sex="男",Hobby="看书" },
            };
            return stus; 
        }
