title: ASP.net MVC Return File and Redirect
body: <p>I have a controller that returns csv file. I want to redirect to an action after this has displayed, i.e. return to the home view.
  The controller logic is shown below: </p>
  
  <pre><code>public ActionResult DownloadCSV(string fileName)
  {
      string csv;
      using (StreamReader sr = new StreamReader(fileName))
      {
          csv = sr.ReadToEnd();
      }
      return File(new System.Text.UTF8Encoding().GetBytes(csv), "text/csv", "Export.csv");
  }
  </code></pre>
