Answer 2

Point p=this.PointToClient(txtTemp.PointToScreen(Point.Empty));
这种更好点

Answer 3

如果不知道有多个父容器,就需要遍历....把坐标加起来.....      Point po = new Point(0, 0);
      private void GetCtlLocation(Control ctl,bool )
      {
        if ()
        {
          po = new Point(ctl.Location.X, ctl.Location.Y);
        }
        if (ctl != null)
        {
          if (ctl.Parent != null)
          {
            po.X += ctl.Parent.Location.X;
            po.Y += ctl.Parent.Location.Y;
            GetCtlLocation(ctl.Parent, false);
          }
        }
      }
