都说的多明白了，非要代码才能懂么？！
            List<IntPtr> lstHandle = new List<IntPtr>();            IList<Rectangle> rectList = CalcPanelRectangle(16, groupBox2.Size);
            foreach (Rectangle rect in rectList)
            {
                Panel panel = new Panel(); 
                panel.BackColor = Color.Black;
                panel.Width = rect.Width;
                panel.Height = rect.Height;
                panel.Left = rect.X;
                panel.Top = rect.Y;
                panel.DoubleClick += new EventHandler(panel_DoubleClick);                lstHandle.Add(panel.Handle);
                groupBox2.Controls.Add(panel);
