title: String URL to RouteValueDictionary
body: <p>Is there as easy way to convert string URL to RouteValueDictionary collection? Some method like <code>UrlToRouteValueDictionary(string url)</code>.</p>
  
  <p>I need such method because I want to 'parse' URL according to my routes settings, modify some route values and using urlHelper.RouteUrl() generate string URL according to modified RouteValueDictionary  collection.</p>
  
  <p>Thanks.</p>
