Get url without querystring

Question

I have a URL like this:

http://www.example.com/mypage.aspx?myvalue1=hello&myvalue2=goodbye

I want to get http://www.example.com/mypage

Answer 1

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

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:

var url = Request.Url?.AbsoluteUri.TrimQueryString()
