title: MVC - Passing Data with RedirectToAction()
body: <p>I'd like to take data entered in an MVC user form and display it in a different view.</p>
  
  <p>The class has the following private variable:</p>
  
  <pre><code>IList&lt;string&gt; _pagecontent = new List&lt;string&gt;();
  </code></pre>
  
  <p>The following action accepts a FormCollection object, validates it, and passes it on to the "Preview" view as a List:</p>
  
  <pre><code>[Authorize(Roles = "Admins")]
  [ValidateInput(false)]
  [AcceptVerbs(HttpVerbs.Post)]
  public ActionResult UpdateContent(FormCollection collection)
  {
      if (ModelState.IsValid)
      {
          string PageToInsert = collection["PageToInsert"];
          string PageHeader = collection["PageHeader"];
          string PageBody = collection["PageBody"];
  
          //validate, excluded...
  
          _pagecontent.Add(PageToInsert);
          _pagecontent.Add(PageHeader);
          _pagecontent.Add(PageBody);
  
      }
      return RedirectToAction("Preview", _pagecontent);
  }
  </code></pre>
  
  <p>The Preview view has the following Page Directive for passing a strongly typed object List:</p>
  
  <pre><code>&lt;%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Template.Master" Inherits="System.Web.Mvc.ViewPage&lt;List&lt;string&gt;&gt;" %&gt;
  </code></pre>
  
  <p>I would expect to be able to use the Model object to get my data, but alas I cannot.  At the following line, I get an <code>error index out of bounds</code> exception, stating the index must be non-negative and less than the size of the collection:</p>
  
  <pre><code>&lt;% if (Model[0].ToString() == "0") { %&gt;
  </code></pre>
  
  <p>And some strange parameters have been added to the URL, as it resolves to 
  <code>http://localhost:1894/Admin/Preview?Capacity=4&amp;Count=3</code></p>
  
  <p>So I have two questions:</p>
  
  <ol>
  <li>When I call RedirectToAction and pass it my List, why is it inaccessible in the view's Model object?  </li>
  <li>What is the proper way to go about doing what I'm trying to do, namely pass a collection of strings to a view for display there?</li>
  </ol>
