body: <p>My question is part of this problem:  </p>
  
  <p>I recieve a collection of id's from a form. I need to get the keys, convert them to integers and select the matching records from the DB.  </p>
  
  <pre><code>[HttpPost]
  public ActionResult Report(FormCollection collection)
  {
      var listofIDs = collection.AllKeys.ToList();  
      // List&lt;string&gt; to List&lt;int&gt;
      List&lt;Dinner&gt; dinners = new List&lt;Dinner&gt;();
      dinners= repository.GetDinners(listofIDs);
      return View(dinners);
  }
