（悬赏20元）使用VS 2010开发asp.net/C#，但提示 错误 "_Default"不包含"txtName"的定义，该怎么处理
Default.aspx代码如下：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>页面跳转并传递参数</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<table style="font-size: 9pt">
<tr>
<td style="width: 61px">
姓名：</td>
<td style="width: 100px">
<asp:TextBox ID="txtName" runat="server"></asp:TextBox></td>
</tr>
<tr>
<td style="width: 61px">
性别：</td>
<td style="width: 100px">
<asp:RadioButton ID="rbtnSex1" runat="server" Checked="True" Text="男" GroupName="Sex" />
<asp:RadioButton ID="rbtnSex2" runat="server" Text="女" GroupName="Sex" /></td>
</tr>
<tr>
<td style="width: 61px">
</td>
<td style="width: 100px">
<asp:Button ID="btnOK" runat="server" OnClick="btnOK_Click" Text="确定" /></td>
</tr>
</table>
</div>
</form>
</body>
</html>
