//NavigationService.GetNavigationService(this).Navigate(new Uri("Page1.xaml", UriKind.Absolute));
//NavigationService.GetNavigationService(this).GoForward();向后转
//NavigationService.GetNavigationService(this).GoBack(); 向前转
//NavigationService.GetNavigationService(this).Navigate(new Uri("Page1.xaml", UriKind.Relative));
//NavigationService.GetNavigationService(this).GoForward();向后转
//NavigationService.GetNavigationService(this).GoBack(); 向前转
//另外还可以以实现windows跳转到page:相对路径
// NavigationWindow window = new NavigationWindow();
//window.Source = new Uri("Page1.xaml", UriKind.Relative);
//window.Show();
//绝对路径
NavigationWindow window = new NavigationWindow();
window.Source = new Uri(path, UriKind.Absolute);
window.Show();
