title: How to change gtk theme in GTK# on Windows?
body: <p>I need to change GUI theme in GTK#. I tried something, but it is still far from ideal. Here is my code:</p>
  
  <pre><code>        string Resource_File = "Black-Diamond\\gtk-2.0\\gtkrc";
          Application.Init ();
          if (System.IO.File.Exists (Resource_File)) {
              Gtk.Rc.AddDefaultFile (Resource_File);
              Gtk.Rc.Parse (Resource_File);
          } else {
              ;
          }
          MainWindow win = new MainWindow ();
          win.Show ();
          Application.Run ();
  </code></pre>
  
  <p>Output:</p>

  <p>That's ok, but not what I expected(some elements don't look like in <a href="http://gnome-look.org/content/show.php/Black-Diamond?content=94653" rel="nofollow noreferrer">original theme</a>). </p>
  
  <p>Can you tell me how I can change GUI theme in GTK# on windows?
  Thanks!</p>
