winform无边框窗口拖动

无边框的窗口想拖动，只需要在置顶的容器上添加对应的mousedown 和 mousemove 事件就可以实现了。代码如下：

         //拖动窗口
         private Point mPoint = new Point();

         private void panel1_MouseDown(object sender, MouseEventArgs e)
         {
             mPoint.X = e.X;
             mPoint.Y = e.Y;
         }

         private void panel1_MouseMove(object sender, MouseEventArgs e)
         {
             if (e.Button == MouseButtons.Left)
             {
                 Point myPosittion = MousePosition;
                 myPosittion.Offset(-mPoint.X, -mPoint.Y);
                 Location = myPosittion;
             }
         }
