How I can get screen orientation?

问题:

I'm entering number of screen on which I want to show the form. And I must get screen orientation. Does anybody know how to do that?

 public UIManager(int screenIndex)
    {
        this.ScreenIndex = screenIndex;            

        try
        {
            Screen[] all_screens;
            all_screens = Screen.AllScreens;

            if (all_screens.Length >= ScreenIndex)
            {
                this.customer_form.Left = all_screens[this.ScreenIndex].Bounds.Width;
                this.customer_form.Top = all_screens[this.ScreenIndex].Bounds.Height;                    
                this.customer_form.Show();
            }
        }
        catch
        {
            //Do nothing
        }
    }

You can use the value from the Windows.Graphics.Display.DisplayInformation class, returned by DisplayInformation.getForCurrentView() and its currentOrientation property:

 DisplayOrientations currentOrientation = Windows.Graphics.Display.DisplayProperties.CurrentOrientation;

From the official doc:
