string url=Request.RawUrl;
(或 string url=Request.Url.PathAndQuery;)
url= /aaa/bbb.aspx?id=5&name=kelli
【3】获取 站点名+页面名：
string url=HttpContext.Current.Request.Url.AbsolutePath;
(或 string url= HttpContext.Current.Request.Path;)
url= aaa/bbb.aspx
【4】获取 域名：
string url=HttpContext.Current.Request.Url.Host;
