string url = "http://www.example.com/mypage.aspx?myvalue1=hello&myvalue2=goodbye";
    string path = url.split('?')[0];

试试这个:

urlString=Request.RawUrl.ToString.Substring(0, Request.RawUrl.ToString.IndexOf("?"))

从这里:http://www.example.com/mypage.aspx?myvalue1=hello&myvalue2=goodbye 你会得到这个:mypage.aspx

好的答案也在这里找到了答案来源

Request.Url.GetLeftPart(UriPartial.Path)

System.Uri。GetComponents，只是指定你想要的组件。

Uri uri = new Uri("http://www.example.com/mypage.aspx?myvalue1=hello&myvalue2=goodbye");
uri.GetComponents(UriComponents.SchemeAndServer | UriComponents.Path, UriFormat.UriEscaped);

输出:

http://www.example.com/mypage.aspx

    string url = "http://www.example.com/mypage.aspx?myvalue1=hello&myvalue2=goodbye";
    string path = url.split('?')[0];

Silverlight的解决方案:

string path = HtmlPage.Document.DocumentUri.GetComponents(UriComponents.SchemeAndServer, UriFormat.Unescaped);
