1.先创建一个名为Customer的实体类,代码如下:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;namespace Cdm.LinqToXml
{public class Customer{public int ID { set; get; }public string Name { set; get; }public string Address { set; get; }public int Age { set; get; }}
}

2.在默认页面中添加GridView控件,代码如下:

<form id="form1" runat="server"><div><asp:GridView ID="MyGv" runat="server" AutoGenerateColumns="False" DataKeyNames="ID" onrowcommand="MyGv_RowCommand"><Columns><asp:CommandField CausesValidation="false" ShowSelectButton="true" ButtonType="Image"  SelectImageUrl="~/right.gif"/><asp:BoundField DataField="ID" HeaderText="ID" /><asp:BoundField DataField="Name" HeaderText="Name" /><asp:BoundField DataField="Address" HeaderText="Address" /><asp:BoundField DataField="Age" HeaderText="Age" /></Columns></asp:GridView></div></form>

注意在这里得写了一个得到当前行的主键的事件

onrowcommand="MyGv_RowCommand"

3.后到代码将给Customer这个实体类赋值,代码如下所示:

protected void Page_Load(object sender, EventArgs e){List<Customer> list = new List<Customer>();list.Add(new Customer{ID = 1,Name = "caodaiming",Address = "四川",Age = 23});list.Add(new Customer{ID = 2,Name = "caodaiming",Address = "四川",Age = 23});list.Add(new Customer{ID = 4,Name = "caodaiming",Address = "四川",Age = 23});MyGv.DataSource = list;MyGv.DataBind();}

4.添加得到当前行的主键事件代码如下:

protected void MyGv_RowCommand(object sender, GridViewCommandEventArgs e){object s = MyGv.DataKeys[int.Parse(e.CommandArgument.ToString())].Value;Response.Write(s.ToString());}

5.运行的效果如下图所示:
