c# - 在两个单独的屏幕上加载两个窗口

Question

我正在尝试创建WPF演示应用程序，其中“主屏幕”上的“主窗口”将用于更新“演示窗口”上的内容，该内容需要在辅助屏幕上。我正在寻找可以帮助我做到这一点的示例或代码段。

另外，我尝试了以下操作，但不起作用:

protected override void OnStartup(StartupEventArgs e)
        {
            base.OnStartup(e);

            var screens = System.Windows.Forms.Screen.AllScreens;
            if (screens.Length > 1)
            {
                var window = new MainWindow
                {
                    WindowStartupLocation = WindowStartupLocation.Manual,
                    WindowState = WindowState.Maximized,

                    Top = screens[0].WorkingArea.Top,
                    Left = screens[0].WorkingArea.Left,
                    Topmost = true
                };
                window.Show();

                var pesentationWindow = new PresentationWindow
                {
                    WindowStartupLocation = WindowStartupLocation.Manual,
                    ShowInTaskbar = false,
                    Top = screens[1].WorkingArea.Top,
                    Left = screens[1].WorkingArea.Left,
                    Topmost = true
                };
                pesentationWindow.Show();
            }
        }

您可以通过这种方式使用Screen对象

protected override void OnStartup(StartupEventArgs e)
{
    base.OnStartup(e);

    Window1 w1 = new Window1();
    Window2 w2 = new Window2();


    Screen s1 = Screen.AllScreens[0];
    Screen s2 = Screen.AllScreens[1];

    Rectangle r1 = s1.WorkingArea;
    Rectangle r2 = s2.WorkingArea;

    w1.Top = r1.Top;
    w1.Left = r1.Left;

    w2.Top = r2.Top;
    w2.Left = r2.Left;

    w1.Show();
    w2.Show();

    w2.Owner = w1;


}
