c＃：窗口进入第二个监视器然后跳回主监视器

Question

下面是简化代码，奇怪的是窗口在一秒钟内停留在第二台显示器上，然后返回第一台主显示器。必须有一个窗口设置或外部程序导致它。因为相同的代码适用于具有双屏幕的另一台计算机。我确定并仔细检查第二个监视器是否在索引1中：showOnMonitor（1，Q）;

 Q = new queue(); 
 showOnMonitor(1, Q);
 Q.Show();

public static void showOnMonitor(int monitor, Window w2)
        {
            Screen[] sc;
            sc = Screen.AllScreens;

            if ( monitor >= sc.Length )
            {
                monitor = 0;
            }


            w2.WindowStartupLocation = WindowStartupLocation.Manual;

            var workingArea = sc[monitor].WorkingArea;
            w2.Left = workingArea.Left;
            w2.Top = workingArea.Top;
            w2.Width = workingArea.Width;
            w2.Height = workingArea.Height;

        }

Answer 1

好的，我不知道为什么会这样。但这是解决方案。

Q = new queue();
Q.Show();
Thread.Sleep( 100 ); //need to delay first before moving the position
showOnMonitor(1, Q);

public static void showOnMonitor(int monitor, Window w2)
        {
            Screen[] sc;
            sc = Screen.AllScreens;

            if ( monitor >= sc.Length )
            {
                monitor = 0;
            }


            w2.WindowStartupLocation = WindowStartupLocation.Manual;

            var workingArea = sc[monitor].WorkingArea;
            w2.Left = workingArea.Left;
            w2.Top = workingArea.Top;
            w2.Width = workingArea.Width;
            w2.Height = workingArea.Height;

        }
