1.先声明一个Studnet类

class Student
    {
        public string Name { get; set; }
        public int Age { get; set; }
    }

2.准备数据和绑定数据

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace List绑定DataGridView
{
    public partial class Form1 : Form
    {
        List<Student> list = new List<Student>();
        Dictionary<string,Student> studic = new Dictionary<string,Student>();
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            dataGridView1.AutoGenerateColumns = false;
            //准备数据
            //Cocl();
            cocl();
            //绑定数据
            //prepareDate();
            prepareDateSoure();
        }
        public void Cocl ()
        {
            Student stu = new Student();
            stu.Name = "张三";
            stu.Age = 10;
            Student stu2 = new Student();
            stu2.Name = "李四";
            stu2.Age = 12;
            Student stu3 = new Student();
            stu3.Name = "王五";
            stu3.Age = 20;
            list.Add(stu);
            list.Add(stu2);
            list.Add(stu3);

        }
        public void prepareDate()
        {
            dataGridView1.DataSource = new BindingList<Student>(list);
        }
        public void cocl()
        {
            Student stu = new Student();
            stu.Name = "张三";
            stu.Age = 10;
            Student stu2 = new Student();
            stu2.Name = "李四";
            stu2.Age = 12;
            Student stu3 = new Student();
            stu3.Name = "王五";
            stu3.Age = 20;
            studic.Add(stu.Name, stu);
            studic.Add(stu2.Name, stu2);
            studic.Add(stu3.Name, stu3);

        }
        public void prepareDateSoure()
        {
            dataGridView1.DataSource = new BindingList<Student>(studic.Values.ToList());


        }
