title: Passing querystrings to RedirectToRouteResult (beside controller and action)
body: <p>I have the following code:</p>
  
  <pre><code>var routeDictionary = new RouteValueDictionary {{"action", "Login"}, {"controller", "Persons"}};
  filterContext.Result = new RedirectToRouteResult(routeDictionary);
  </code></pre>
  
  <p>That will produce "<code>/Persons/Login</code>"</p>
  
  <p>How can I pass an aditional querystring to the previous code? so that it produces "<code>/Persons/Login/?someQuerystring=someValue</code>"</p>
