你可以自己拖好一个窗体,必要时候show出来不就好了

比较简单的方法是先做个 Page
然后用 window.Content = page;

NavigationWindow w = new NavigationWindow();
w.ShowsNavigationUI = false; // <-- 不显示导航栏
// w.Navigate(new Uri("pages/helloworld.xaml", UriKind.Relative)); // <-- 自定义的 page
w.Navigate(new Uri("http://www.google.com"));
w.Show();
