How to change gtk theme in GTK# on Windows?

问题

I need to change GUI theme in GTK#. I tried something, but it is still far from ideal. Here is my 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 ();

Output:

That's ok, but not what I expected(some elements don't look like in original theme).

Can you tell me how I can change GUI theme in GTK# on windows? Thanks!
