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(new[] {'?'})[0];

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

仅为url名!!

好的答案也在这里找到了答案来源

Request.Url.GetLeftPart(UriPartial.Path)

this.Request.RawUrl.Substring(0, this.Request.RawUrl.IndexOf('?'))

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