@(编程)

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); 
        } 
    } 
}
