C# Winform 双屏显示

双屏显示1

// 利用WinForm中的Screen类，即可比较方便地实现多窗体分别在多个屏幕上显示。

        //•获取当前系统连接的屏幕数量： Screen.AllScreens.Count();

        //•获取当前屏幕的名称：string CurrentScreenName = Screen.FromControl(this).DeviceName;

        //•获取当前屏幕对象：Screen CurrentScreen = Screen.FromControl(this);

        //•获取当前鼠标所在的屏幕：Screen CurrentScreen = Screen.FromPoint(new Point(Cursor.Position.X, Cursor.Position.Y));

        //•让窗体在第2个屏幕上显示：

        //this.Left = ((Screen.AllScreens[1].Bounds.Width - this.Width) / 2);

        //this.Top = ((Screen.AllScreens[1].Bounds.Height - this.Height) / 2);

        private void showOnMonitor(int showOnMonitor)

        {

            Screen[] sc;

            sc = Screen.AllScreens;

            if (showOnMonitor >= sc.Length)

            {

                showOnMonitor = ;

            }

            this.FormBorderStyle = FormBorderStyle.None; //无边框全屏显示

            this.StartPosition = FormStartPosition.Manual;

            this.Location = new Point(sc[showOnMonitor].Bounds.Left, sc[showOnMonitor].Bounds.Top);

            //this.Location = new Point(((sc[showOnMonitor].Bounds.Width-this.Width)/2), ((sc[showOnMonitor].Bounds.Height-this.Height)/2));

            // If you intend the form to be maximized, change it to normal then maximized.

            //this.WindowState = FormWindowState.Normal;

            this.WindowState = FormWindowState.Maximized;//最大化窗口

        }

如果接双显卡时showOnMonitor 参数等于0为主屏，1为扩展屏

双屏显示1

双屏显示2

 private void showOnMonitor2()

        {

            Screen[] sc;

            sc = Screen.AllScreens;

            //get all the screen width and heights

            Form1 f = new Form1();

            f.FormBorderStyle = FormBorderStyle.None;

            f.Left = sc[].Bounds.Width;

            f.Top = sc[].Bounds.Height;

            f.StartPosition = FormStartPosition.Manual;

            f.Location = sc[].Bounds.Location;

            Point p = new Point(sc[].Bounds.Location.X, sc[].Bounds.Location.Y);

            f.Location = p;

            f.WindowState = FormWindowState.Maximized;

            f.Show();

        }

接入双显卡时sc[]为主屏、sc[]扩展屏

  this.Location = new Point(,);

            Screen[] sc;

            sc = Screen.AllScreens;

            this.Width = (sc[].Bounds.Width + sc[].Bounds.Width);//+20;

            this.Height = (sc[].Bounds.Height); //+200;

            this.FormBorderStyle = FormBorderStyle.None; //边框样式

            webBrowser1.Width = sc[].Bounds.Width;

            webBrowser1.Height = sc[].Bounds.Height;

            webBrowser1.Location = new Point(sc[].Bounds.Location.X, sc[].Bounds.Location.Y);

            webBrowser1.Url = new Uri("http://www.google.com.hk");

            webBrowser2.Width = sc[].Bounds.Width;

            webBrowser2.Height = sc[].Bounds.Height;

            webBrowser2.Location = new Point(sc[].Bounds.Location.X, sc[].Bounds.Location.Y);

            webBrowser2.Url = new Uri("http://www.baidu.com");
