Getting the Virtual Path of a Request in c#

This simple bit of code will get you the Virtual Path of your current request.

public static string GetVirtualPath(string url)
{
    if (HttpContext.Current.Request.ApplicationPath == "/")
    {
        return "~" + url;
    }

    return Regex.Replace(url, "^" + 
                   HttpContext.Current.Request.ApplicationPath + "(.+)$", "~$1");
}

Example Usage

 // the Url is http://www.GeekZilla.co.uk/DemoApp/default.aspx
 // and in my instance, DemoApp is the root of the application

 string myVirtualPath = GetVirtualPath(HttpContext.Current.Request.Raw));

 // the result would be ~/default.aspx

Notes

Don't forget to include:

using System.Text.RegularExpressions;
