title: Is it possible to set FolderBrowserDialog.RootFolder to an arbitrary path from a string?
body: <p>I'm trying to do this</p>
  
  <pre><code>FolderBrowserDialog dlg = new FolderBrowserDialog();
  dlg.RootFolder = "C:\SomeUserSelectedFolder";
  </code></pre>
  
  <p>But <code>RootFolder</code> is a <code>System.Environment.SpecialFolder</code>.</p>
  
  <p>Does this mean I can only set that to places like MyDocuments or the Desktop?!?</p>
