代码如下：

<% @ Page Language = " C# " AutoEventWireup = " true " CodeFile = " Default.aspx.cs " Inherits = " _Default " %>

cs代码：

using System;

using System.Data;

using System.Configuration;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

public partial class _Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

}

protected void Button1_Click(object sender, EventArgs e)

{

//System.Threading.Thread.Sleep(3000);

int j = 0;

for (int i = 0; i < 100000000; i++)

{

j = i+j;

}

if (TextBox1.Text.Equals(TextBox2.Text))

{

Response.Redirect("/login.aspx");

}

else

{

Response.Redirect("/error.aspx");

}

将表单代码去掉替换如下：
<iframe scrolling="no" frameborder="0" marginwidth="0" marginheight="0" src="bar.htm" /></iframe>

可见还需要一个bar.htm。这样我们就建个：
