I have a form posting to an action with MVC. I want to pull the selected drop down list item from the FormCollection in the action. How do I do it?

My Html form:

<% using (Html.BeginForm())
    {%>
    <select name="Content List">
    <% foreach (String name in (ViewData["names"] as IQueryable<String>)) { %>
          <option value="<%= name %>"><%= name%></option>
    <% } %>
    </select>
    <p><input type="submit" value="Save" /></p>
<% } %>

My Action:

[HttpPost]
public ActionResult Index(FormCollection collection)
{
    //how do I get the selected drop down list value?
    String name = collection.AllKeys.Single();
    return RedirectToAction("Details", name);
}
