来自那篇文章的评论:

The SaveFileDialogWithEncoding example is great. However, the look and feel are "old style" -- in other words, the buttons and controls don't have the new "XP look" (i.e. rounded buttons, etc.). It's probably a flag setting in one of the fields in the OPENFILENAME structure and I'm looking into that. I was just wondering if you (or anyone else) had any insight to solving that problem.

Never mind -- figured it out. Before you instantiate the form object you need to call Application.EnableVisualStyles() like so:

[STAThread]
static void Main() 
{
  Application.EnableVisualStyles();
  Application.Run(new Form1());
}
