Login.aspx文件中，代码如下：

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

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</head>

<body>

<asp:Label ID="Label7" runat="server" Font-Size="XX-Large" ForeColor="Maroon"

Height="35px" style="margin-left: 186px" Text="请登录" Width="103px"></asp:Label>

<br />

<asp:Label ID="Label2" runat="server" Font-Size="X-Large" ForeColor="#CC00CC"

Height="27px" style="margin-left: 90px" Text="用户：" Width="90px"></asp:Label>

<asp:TextBox ID="TextBox1" runat="server" Height="21px"></asp:TextBox>

<asp:RequiredFieldValidator ID = "RequiredFieldValidator1"

ControlToValidate = "TextBox1"

Display = "Dynamic"

ErrorMessage = "不能为空"

runat = "server" />

<br />

<asp:Label ID="Label3" runat="server" Font-Size="X-Large" ForeColor="#CC3399"

Height="27px" style="margin-left: 90px" Text="密码：" Width="87px"></asp:Label>

<asp:TextBox ID="TextBox2" runat="server" style="margin-left: 2px"></asp:TextBox>

<asp:RequiredFieldValidator ID = "RequiredFieldValidator2"

ControlToValidate = "TextBox2"

ErrorMessage = "密码不能为空"

runat = "server" />

<br />

<asp:CheckBox ID="Persist" runat="server" style="margin-left: 172px"

Text="记住密码" Width="120px" oncheckedchanged="Persist_CheckedChanged" />

<br />

<asp:Button ID="Submit1" OnClick="Login_Click" runat="server" Text="登陆"

Font-Names="黑体" Font-Size="X-Large" Height="42px" style="margin-left: 83px"

Width="76px" />

<asp:Label ID="Label4" runat="server" style="margin-left: 35px" Width="200px"></asp:Label>

</div>

</form>

</body>

</html>

Login.aspx.cs文件中，代码如下：

using System;

using System.Collections;

using System.Configuration;

using System.Data;

using System.Linq;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.HtmlControls;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Xml.Linq;

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

{

protected void Page_Load(object sender, EventArgs e)

{

}

protected void Login_Click(object sender, EventArgs e)

{

if ((TextBox1.Text == "sa") && (TextBox2.Text == "sa"))

{

FormsAuthentication.RedirectFromLoginPage(TextBox1.Text, Persist.Checked);

}

else{

Label4.Text = "验证不成功，请再试一次";

}

代码参考如上，测试过应该没什么问题，当然了，之前还要在web.config中写入如下代码：

<authentication mode="Forms">

<forms loginUrl="Login.aspx" name=".aspsafetest">

</forms>

</authentication>

<authorization>

<deny users="?"/>

</authorization>

然后把更改页面的form id，如上文中已经加上了form id="form1"的字样，个人认为这表示的是程序执行时的登录顺序。
