title: FileSystem.CopyFile user actions
body: <p>I have an MVC3 C#.Net web app.  In my HTML View, I am using the standard Windows file input</p>
  
  <pre><code>&lt;input style="border:thin solid #ccc;width:270px; background-color: #FFFFFF;" type="file" name="Name" id="Name"/&gt;
  </code></pre>
  
  <p>In the Controller I am using the FileSystem.CopyFile() method found in Microsoft.VisualBasic.FileIO.  </p>
  
  <pre><code>FileSystem.CopyFile(fileName, fileDirectory +"\\" + attachments.Name, UIOption.AllDialogs);
  </code></pre>
  
  <p>It's working fine.  However, I need to know what selection the user makes on the dialog box.  How can I trap whether the user has selected "Copy &amp; Replace", "Don't Copy", "Copy and Keep both files"?</p>
