53调用测试如下：
54            int y = Screen.PrimaryScreen.WorkingArea.Height - 180;
55            int x = Screen.PrimaryScreen.WorkingArea.Width - 180;
56            Point p = new Point(x, y);
57            MouseHelper.Instance.MoveMouseToPoint(p);

C#获取指定控件所在屏幕的位置

1　　　　　 int x = this.dgvList.Location.X;
2            int y = this.dgvList.Location.Y;
3            Point p = new Point(x, y);
4            Point pp = this.dgvList.PointToScreen(p);
5            MouseHelper.Instance.MoveMouseToPoint(pp);
