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！

 

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());
    }

}
