title: How to retrieve form values from HTTPPOST, dictionary or?
body: <p>I have an MVC controller that has this Action Method:</p>
  
  <pre><code>[HttpPost]
  public ActionResult SubmitAction()
  {
       // Get Post Params Here
   ... return something ...
  }
  </code></pre>
  
  <p>The form is a non-trivial form with a simple textbox.</p>
  
  <p><strong>Question</strong> </p>
  
  <p>How I access the parameter values? </p>
  
  <p>I am not posting from a View, the post is coming externally. I'm assuming there is a collection of key/value pairs I have access to. </p>
  
  <p>I tried <code>Request.Params.Get("simpleTextBox");</code> but it returns error "Sorry, an error occurred while processing your request.".</p>
