C#代码是-

And the c# code is-

{
var style = (Style)Resources["GlassStyle"];
           this.Style = style;
       }
       private void _OnStandardChromeClicked(object sender, RoutedEventArgs e)
       {
           this.Style = null;
       }

       private void _OnGradientChromeClicked(object sender, RoutedEventArgs e)
       {
           var style = (Style)Resources["GradientStyle"];
           this.Style = style;
       }

       private void _OnGlassyChromeClicked(object sender, RoutedEventArgs e)
       {
           var style = (Style)Resources["GlassStyle"];
           this.Style = style;
       }

       private void _OnSystemCommandCloseWindow(object sender, ExecutedRoutedEventArgs e)
       {
           SystemCommands.CloseWindow((Window)e.Parameter);
       }
