            MoveMouseToPoint(centerP);

}

调用测试如下：

            int y = Screen.PrimaryScreen.WorkingArea.Height - 180;

            int x = Screen.PrimaryScreen.WorkingArea.Width - 180;

            Point p = new Point(x, y);

            MouseHelper.Instance.MoveMouseToPoint(p);

   　　　　　 int x = this.dgvList.Location.X;

            int y = this.dgvList.Location.Y;

            Point p = new Point(x, y);

            Point pp = this.dgvList.PointToScreen(p);

            MouseHelper.Instance.MoveMouseToPoint(pp);
