1.在OnNavigateTo 裡，設定是否顯示Back Button

SystemNavigationManager.GetForCurrentView().AppViewBackButtonVisibility = frame.CanGoBack ? AppViewBackButtonVisibility.Visible : AppViewBackButtonVisibility.Collapsed;

2. 註冊BackRequested事件

SystemNavigationManager.GetForCurrentView().BackRequested += View_BackRequested

C#:

 public static class NavigationManager
    {
        static NavigationManager()
        {
            SystemNavigationManager.GetForCurrentView().BackRequested += View_BackRequested;
        }

        private static void View_BackRequested(object sender, BackRequestedEventArgs e)
        {
            var frame = Window.Current.Content as Frame;

            if (frame == null)
            {
                return;
            }

            if (!frame.CanGoBack)
            {
                return;
            }

            if (e.Handled)
            {
                return;
            }

            e.Handled = true;

            frame.GoBack();
        }

        public static void ShowBackButtonIfNeeded()
        {
            var frame = Window.Current.Content as Frame;

            if (frame == null)
            {
                return;
            }

            SystemNavigationManager.GetForCurrentView().AppViewBackButtonVisibility = frame.CanGoBack ? AppViewBackButtonVisibility.Visible : AppViewBackButtonVisibility.Collapsed;
        }
    }
