DataGridView 控件绑定List<T>

DataGridView 控件绑定List<T>示例：

虽然最终只需要几行简单的代码就可完成绑定，可是由于一些小问题搞了半天才显示出来。

有一点注意，要显示的数据结构中，指向对象的属性，必须是属性，而不能字段！即使是public也不行！

代码

using System;
using System.Windows.Forms;

public class DataBind : Form
{
private DataGridView dataGridView1 = new DataGridView();
private BindingSource bindingSource1 = new BindingSource();

public DataBind ()
{
this.Load += new System.EventHandler(DataBind _Load);
}

private void DataBind _Load(object sender, System.EventArgs e)
{

DataGridViewTextBoxColumn col1 = new DataGridViewTextBoxColumn();
col1.HeaderText = "ID";
col1.DataPropertyName = "ID";
col1.Name = "ID";
DataGridViewTextBoxColumn col2 = new DataGridViewTextBoxColumn();
col2.HeaderText = "姓名";
col2.DataPropertyName = "Name";
col2.Name = "Name";
this.dataGridView1.Columns.Add(col1);
this.dataGridView1.Columns.Add(col2);

IList<UserData> list = new List<UserData>();
list.Add(new UserData("001", "tom"));
list.Add(new UserData("002", "bill"));
this.dataGridView1.DataSource = list;

}

#region "business object"
public class UserData
{
private string _ID;
private string _Name;
public string ID;
//public string ID
//{
//    get { return _ID; }
//    set { _ID = value; }
//}

public string Name
{
get { return _Name; }
set { _Name = value; }
}

public UserData(string id, string name)
{
_ID = id;
_Name = name;
}

#endregion

[STAThread]
public static void Main()
{
Application.Run(new DataBind());
}

}
