【C#】透屏幕，屏幕扩展

             if (!SCREEN_STATE)
             {
                 if (System.Windows.Forms.Screen.AllScreens.Count() > )
                 {
                     System.Windows.Forms.Screen s2 = System.Windows.Forms.Screen.AllScreens[];
                     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！
