一、登录界面设置
<body>
<form id="form1" runat="server" target="_top">
<div>
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Login"
Width="115px" />
<asp:Image runat="server" ImageUrl="~/ValidateImage.ashx" />
</div>
</form>
</body>
二、退出代码
string url = Request.ApplicationPath + "/Login.aspx";
//Utility.Jscript.alert("本次登录已经超时，请重新登录系统");
Response.Write(" <script>top.location='" + url + "' ;</script>");
Response.End();
