title: Get form data specifying the key on Webapis using MultipartFormDataStreamProvider
body: <p>I am currently using this code to get my form data using web apis and MultipartFormDataStreamProvider</p>
  
  <pre><code>   await Request.Content.ReadAsMultipartAsync(provider);
  
              // This illustrates how to get the form data.
              foreach (var key in provider.FormData.AllKeys)
              {
                  foreach (var val in provider.FormData.GetValues(key))
                  {
                      sb.Append(string.Format("{0}: {1}\n", key, val));
                  }
              }
  </code></pre>
  
  <p>Is it possible to get the form data not using the foreach loops but specifing the key? Using something like this var name = Form["txtFormValue"];</p>
  
  <p>I already tried  string r = provider.FormData.("form-email"); but it returns null.</p>
