Question

我正在尝试使用媒体元素创建一个wpf视频播放器。我的目标是为该应用程序制作多个窗口。每个窗口都会显示在不同的显示器上。就像MainWindow将获得主显示器的分辨率并调整自身以全屏显示。辅助监视器上的第二个窗口等等......

到目前为止，我已在主监视器上制作了MainWindow全屏。但我不知道如何用它的分辨率在第二台显示器上显示第二个窗口。请帮忙。

Answer 1

最简单的选择是显示它。在show（）方法之后，调整它的大小。

            // display on second window
        NewWindow win = new NewWindow();
        System.Windows.Forms.Screen s1 = System.Windows.Forms.Screen.AllScreens[2];

        System.Drawing.Rectangle r1 = s1.WorkingArea;
        win.WindowState = System.Windows.WindowState.Normal;
        win.WindowStartupLocation = System.Windows.WindowStartupLocation.Manual;
        win.Top = r1.Top;
        win.Left = r1.Left;

        win.Show();
        win.WindowState = System.Windows.WindowState.Maximized;

Answer 2

每个屏幕都有空间坐标，你实际上并没有在其他屏幕的坐标上放置一个窗口。

在这台机器上-1280,0是左侧监视器，0,0是主监视器，1280,0是右侧监视器。不知道多屏幕操作的程序通常对此没有任何问题，尽管当放置在左侧监视器上时，足够老的东西可以做一些奇怪的事情（试图阻止弹出窗口离开屏幕边缘，不知道负面坐标可见。）

您可以尝试这样的事情：

    private System.Windows.Forms.Screen findScreen(string screenName) {
        System.Windows.Forms.Screen res = System.Windows.Forms.Screen.AllScreens.FirstOrDefault(s => s.DeviceName == screenName);
        if (res == null)
            res = System.Windows.Forms.Screen.AllScreens[0];
        return res;
    }


    private void setupForms() {
        System.Windows.Forms.Screen mainScreen = findScreen(@"\\.\DISPLAY2");
        FrmMain frmMain = new FrmMain()
        {
            WindowStartupLocation = WindowStartupLocation.Manual,
            WindowState = System.Windows.WindowState.Normal,
            Left = mainScreen.WorkingArea.Left,
            Top = mainScreen.WorkingArea.Top,
            Width = mainScreen.WorkingArea.Width,
            Height = mainScreen.WorkingArea.Height
        };

        System.Windows.Forms.Screen secondaryScreen = findScreen(@"\\.\DISPLAY1");
        FrmSecondary frmSecondary = new FrmSecondary()
        {
            WindowStartupLocation = WindowStartupLocation.Manual,
            WindowState = System.Windows.WindowState.Normal,
            Left = secondaryScreen.WorkingArea.Left,
            Top = secondaryScreen.WorkingArea.Top,
            Width = secondaryScreen.WorkingArea.Width,
            Height = secondaryScreen.WorkingArea.Height
        };


    }

我将更新@romanoza的答案

private void SetupWindows()
    {
        System.Windows.Forms.Screen mainScreen = Screen.AllScreens[0]; ;
        WinLeft leftWin = new WinLeft()
        {
            WindowStartupLocation = WindowStartupLocation.Manual,
            WindowState = System.Windows.WindowState.Normal,
            Left = mainScreen.WorkingArea.Left,
            Top = mainScreen.WorkingArea.Top,
            Width = mainScreen.WorkingArea.Width,
            Height = mainScreen.WorkingArea.Height
        };           

        System.Windows.Forms.Screen secondaryScreen = Screen.AllScreens[1];
        WinRight rightWin = new WinRight()
        {
            WindowStartupLocation = WindowStartupLocation.Manual,
            WindowState = System.Windows.WindowState.Normal,
            Left = secondaryScreen.WorkingArea.Left,
            Top = secondaryScreen.WorkingArea.Top,
            Width = secondaryScreen.WorkingArea.Width,
            Height = secondaryScreen.WorkingArea.Height
        };


        leftWin.Show();
        leftWin.WindowState = WindowState.Maximized;
        rightWin.Show();
        rightWin.WindowState = WindowState.Maximized;
        rightWin.Owner = leftWin;
    }
