Get url without querystring

Question

Here's a simpler solution:

var uri = new Uri("http://www.example.com/mypage.aspx?myvalue1=hello&myvalue2=goodbye");
string path = uri.GetLeftPart(UriPartial.Path);

Borrowed from here: Truncating Query String & Returning Clean URL C# ASP.net

You can use System.Uri

Uri url = new Uri("http://www.example.com/mypage.aspx?myvalue1=hello&myvalue2=goodbye");
string path = String.Format("{0}{1}{2}{3}", url.Scheme, 
    Uri.SchemeDelimiter, url.Authority, url.AbsolutePath);

Or you can use substring

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

EDIT: Modifying the first solution to reflect brillyfresh's suggestion in the comments.

This is my solution:

Request.Url.AbsoluteUri.Replace(Request.Url.Query, String.Empty);

Good answer also found here source of answer

Request.Url.GetLeftPart(UriPartial.Path)

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

My way:

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

or

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