    copied!<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>
