title: what is the use of RouteValueDictonary routeValues in Html.BeginForm()
body: <pre><code>@{
      ViewBag.Title = "About Us";
  }
  
  @using (Html.BeginForm(new RouteValueDictionary { {"Action","Index"}}))
  {
  &lt;input type="submit" value="submit"/&gt;
  }
  </code></pre>
  
  <p>When I render </p>
  
  <pre><code>&lt;form action="/Home/Index" method="post"&gt;&lt;input type="submit" value="submit"/&gt;
  </code></pre>
  
  <p>Is this the actual use of RouteValueDictonary. If so I can do this do by HTML.BeginForm("About","Home")</p>
  
  <p>Can some one explain the actual use of RouteValueDictonary.
  Any help will be appreciated.</p>
