Finding the monitor ordering

Question

As shown in the picture. I can find the primary monitor with the Screen library. But once I would also like to find the ordering of the monitor. What I'm trying to make is something like a screensaver.

At first the 1 monitor(which is the primary monitor) will be at the left and the 2nd monitor will be at right. But if I change the order 2 -> 1 .. the primary monitor will be at the right. And the form that I made will go in other unexpected points. Is there anyway to detect this change of order???? Right now my code is this.

private void ResizeScreen()
    {
        // 전체 화면으로 사이즈 설정
        int form_width = 0;
        int form_height = 0;
        int form_x = 0;
        int form_y = 0;
        int sub_screen_width = 0;
        int sub_screen_height = 0;
        foreach (Screen screen in Screen.AllScreens)
        {
            form_width += screen.Bounds.Width;
            NLog.LogManager.GetCurrentClassLogger().Trace("form_width : " + form_width);
            form_height += screen.Bounds.Height;
            NLog.LogManager.GetCurrentClassLogger().Trace("form_height : " + form_height);
            if (form_x > screen.Bounds.X)
                form_x = screen.Bounds.X;
            if (form_y > screen.Bounds.Y)
                form_y = screen.Bounds.Y;

            //form_x = Math.Abs(form_x);
            NLog.LogManager.GetCurrentClassLogger().Trace("form_x : " + screen.Bounds.X);
            NLog.LogManager.GetCurrentClassLogger().Trace("form_y : " + screen.Bounds.Y);

            if (screen.Bounds.X < 0)
                sub_screen_width += screen.Bounds.Width;
            if (screen.Bounds.Y < 0)
                sub_screen_height += screen.Bounds.Height;
        }
        this.Width = form_width;
        this.Height = form_height;
        this.CenterToScreen();
        this.Location = new Point(form_x, form_y);
