title: Can an Action Filter have access to a private object in the Controller?
body: <p>I have </p>
  
  <pre><code>public class FundController 
  {
      private Site _site;
      public ViewResult Fund()
      {
      }
  }
  </code></pre>
  
  <p>I'd like to add an Action Filter to this Fund method:</p>
  
  <pre><code>public class FundController 
  {
      private Site _site;
  
      [MyFilter]
      public ViewResult Fund()
      {
      }
  }
  </code></pre>
  
  <p>but the Action Filter needs access to <code>_site</code>. Is this possible? If so, how?</p>
