项目结构

一、绑定数据方式

通过DataTable绑定

DataTable table =new DataTable();dgv.DataSource = table;

通过ArrayList绑定

class Book{    public string ID { get; set; }    public string No { get; set; }    public string Name { get; set; }}private void InitByDataTable(){    List
    
      list = new List
     
      ();    for (int i = 0; i < 10; i++)    {        list.Add(new Book() {ID = i.ToString(),No = i.ToString(), Name = "Book"+i });    }       dgv.DataSource = list;    //设置可见性    dgv.Columns[0].Visible = false;    //设置列标题    dgv.Columns[1].HeaderText = "编码";    dgv.Columns[2].HeaderText = "名称";    //设置类宽    dgv.Columns[2].Width = 100;}
     
    

通过Dictionary绑定

private void InitByDictionary(){    Dictionary
    
      dictionary = new Dictionary
     
      ();    for (int i = 0; i < 10; i++)    {        dictionary.Add(i.ToString(), "Book" + i);    }    dgv.DataSource = (from v in dictionary                      select new                      {                          ID = v.Key,                          Key = v.Key,                          Value = v.Value                      }).ToArray();}
