利用html的自动刷新代码，不需要.net代码编程。给你一个例子，主要是这句话，
<meta http-equiv="refresh" content="5;URL=
http://www.baidu.com">
<html>
<head>
<meta http-equiv="Content-Language" content="zh-CN">
<meta HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=gb2312">
<title></title>
<meta http-equiv="refresh" content="5;URL=
http://www.baidu.com">
</head>
<body>
</body>
</html>
下面的也行是利用javascript实现的
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>正在进入</title>
</head>
<body>
<form name=loading>
<p align=center> <font color="#0066ff" size="2">正在进入，请稍等</font><font color="#0066ff" size="2" face="Arial">...</font>
<input type=text name=chart size=46 style="font-family:Arial; font-weight:bolder; color:#0066ff; background-color:#fef4d9; padding:0px; border-style:none;">
<input type=text name=percent size=47 style="color:#0066ff; text-align:center; border-width:medium; border-style:none;">
<script>
var bar=0
var line="||"
var amount="||"
count()
function count(){
bar=bar+2
amount =amount + line
document.loading.chart.value=amount
document.loading.percent.value=bar+"%"
if (bar<99)
{setTimeout("count()",100);}
else
{window.location = "
http://www.baidu.com";}
}</script>
</p>
</form>
<p align="center"> 如果您的浏览器不支持跳转,<a style="text-decoration: none" href="
http://www.baidu.com"><font color="#FF0000">请点这里</font></a>.</p>
</body>
