1. 用法

student类

using System.ComponentModel;

namespace WindowsFormsApplication1
{
    public class Student
    {
        public string Id { get; set; }
        [DisplayName("姓名")]
        public string Name { get; set; }
        [DisplayName("性别")]

        public string Gender { get; set; }


        [DisplayName("年级")]
        public string Grade { get; set; }

        [DisplayName("班级")]
        public string Grade111 { get; set; }

    }
}

应用

using System;
using System.Collections.Generic;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            List<Student> data = new List<Student>();
            Student s1 = new Student() { Id = Guid.NewGuid().ToString(), Gender = "男", Grade = "一年级", Name = "小王" };
            data.Add(s1);
            List<string> hideList = new List<string>();
            hideList.Add("Id");
            this.wDataGridView1.MyDataList = data;
            this.wDataGridView1.MyHideList = hideList;
            this.wDataGridView1.MyType = typeof(Student);
            this.wDataGridView1.Repaint();
            Student entity = this.wDataGridView1.GetSelect0BindItem() as Student;
            MessageBox.Show(entity.Name);
        }
    }
}
