复制代码 代码如下:

<%@ Application Language=\"C#\" %>

<script RunAt=\"server\">
void Application_BeginRequest(object sender, EventArgs e)
{
string oldUrl = System.Web.HttpContext.Current.Request.RawUrl; //获取初始url

//~/123.aspx → ~/Index.aspx?id=123
Regex reg = new Regex(@\"^\\/\\d+\\.html\");
if (reg.IsMatch(oldUrl))
{
string id = reg.Match(oldUrl).ToString().Substring(1, reg.Match(oldUrl).ToString().LastIndexOf(\".\") - 1);
Context.RewritePath(\"~/Index.aspx?id=\" + id);
}

//~/123 → ~/Index.aspx?id=123
Regex reg1 = new Regex(@\"^\\/\\d+$\");
if (reg1.IsMatch(oldUrl))
{
string id = reg1.Match(oldUrl).ToString().Substring(1);
Context.RewritePath(\"~/Index.aspx?id=\" + id);
}

//~/index/123 → ~/Index.aspx?id=123
Regex reg3 = new Regex(@\"^\\/index\\/\\d+$\");
if (reg3.IsMatch(oldUrl))
{
string id = reg3.Match(oldUrl).ToString().Substring(7);

}
}
