我的方法:

new UriBuilder(url) { Query = string.Empty }.ToString()

or

new UriBuilder(url) { Query = string.Empty }.Uri

var canonicallink = Request.Url.Scheme + "://" + Request.Url.Authority + Request.Url.AbsolutePath.ToString();

简单的例子是使用子字符串:

string your_url = "http://www.example.com/mypage.aspx?myvalue1=hello&myvalue2=goodbye";
string path_you_want = your_url .Substring(0, your_url .IndexOf("?"));

Request.RawUrl.Split('?')[0]

仅为url名!!

Request.RawUrl.Split(new[] {'?'})[0];

Silverlight的解决方案:

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