You can use <code>System.Uri</code>

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

Or you can use <code>substring</code>

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

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

Here's an extension method using @Kolman's answer. It's marginally easier to remember to use Path() than GetLeftPart. You might want to rename Path to GetPath, at least until they add extension properties to C#.

Usage:

<pre><code>Uri uri = new Uri("http://www.somewhere.com?param1=foo&amp;param2=bar");
string path = uri.Path();
</code></pre>

The class:

<pre><code>using System;

namespace YourProject.Extensions
{
 public static class UriExtensions
 {
 public static string Path(this Uri uri)
 {
 if (uri == null)
 {
 throw new ArgumentNullException("uri");
 }
 return uri.GetLeftPart(UriPartial.Path);
 }
 }
}

I've created a simple extension, as a few of the other answers threw null exceptions if there wasn't a <code>QueryString</code> to start with:

<pre><code>public static string TrimQueryString(this string source)
{ 
 if (string.IsNullOrEmpty(source))
 return source;

 var hasQueryString = source.IndexOf('?') != -1;

 if (!hasQueryString)
 return source;

 var result = source.Substring(0, source.IndexOf('?'));

 return result;
}

Usage:

<pre><code>var url = Request.Url?.AbsoluteUri.TrimQueryString()
