title: Call UrlHelper in models in ASP.NET MVC
body: <p>I need to generate some URLs in a model in ASP.NET MVC. I'd like to call something like UrlHelper.Action() which uses the routes to generate the URL. I don't mind filling the usual blanks, like the hostname, scheme and so on.</p>
  
  <p>Is there any method I can call for that? Is there a way to construct an UrlHelper?</p>
