下面是展示的是几种导航方式：
我们来具体看下xaml文件

} private void button1_Click(object sender, RoutedEventArgs e)
{
//本地话操作，通过方法来跳转
Page2 page = new Page2();

ns.Navigate(page);
} private void button2_Click(object sender, RoutedEventArgs e)
{
//适合游览器，通过属性的方式，uri指向
NavigationService ns = NavigationService.GetNavigationService(this);
ns.Source = new Uri("Page2.xaml", UriKind.Relative);
} private void button3_Click(object sender, RoutedEventArgs e)
{ NavigationService ns = NavigationService.GetNavigationService(this);
ns.Content = new Page2();
}
}
}
