title: asp.net mvc default parameter attribute
body: <p>Is there a way to set a default value on a parameter that was not passed, for eg:</p>
  
  <pre><code>    public ActionResult Index(int? page)
      {}
  </code></pre>
  
  <p>I'd like to have <code>page=0</code> if no page was passed, so I can remove the nullable symbol. I do not want to do this in routing, just on the action itself.</p>
