復制代碼 代碼如下:

if(!Page.IsPostBack)
{
ReUrl = Page.Request.UrlReferrer.ToString().Split('?')[0].ToString() + HttpUtility.UrlEncode(Page.Request.UrlReferrer.Query,System.Text.Encoding.GetEncoding("GB2312"));
if (ReUrl == null || ReUrl == "")
{
ReUrl = HttpContext.Current.Request.Url.PathAndQuery ;
}
ViewState["ReUrl"] = ReUrl;
}

復制代碼 代碼如下:

try
{
string strTemp = Request.UrlReferrer.PathAndQuery ;
}
catch
{
throw new Exception("你不能修改參數!") ;
}
