【C#】透屏幕，屏幕扩展

            if (!SCREEN_STATE)
            {
                if (System.Windows.Forms.Screen.AllScreens.Count() > 1)
                {
                    System.Windows.Forms.Screen s2 = System.Windows.Forms.Screen.AllScreens[1];
                    System.Drawing.Rectangle r2 = s2.WorkingArea;
                    bigScreen = new BigScreen();

                    bigScreen.GridMainContent.Children.Clear();
                    TeamDataPage s = new TeamDataPage();
                    bigScreen.GridMainContent.Children.Add(s);

                    bigScreen.Top = r2.Top;
                    bigScreen.Left = r2.Left;
                    bigScreen.Width = r2.Width;
                    bigScreen.Height = r2.Height;
                    bigScreen.Show();
                    bigScreen.WindowState = WindowState.Maximized;
                    btn_BigScreen.Content = "    停止显示   ";
                    SCREEN_STATE = true;
                }
                else
                {
                    MessageBox.Show("找不到扩展屏幕!");
                }
            }
            else
            {
                btn_BigScreen.Content = "    大屏显示   ";
                if (bigScreen != null)
                    bigScreen.Close();

                SCREEN_STATE = false;
            }

1、根据屏幕宽度，将要透屏的内容显示在主屏幕宽度之外！
