用图片做标题，怎么实现图标放上去可以移动窗体呢？

已搞定

private Point _mousePoint;
      private int topA(Control cc)
      {
         if (cc == null || cc == this) return 0;
         if (cc.Parent == null || cc.Parent == this)
            return cc.Top;
         else
            return topA(cc.Parent) + cc.Top;
      }
      private int leftA(Control cc)
      {
         if (cc == null || cc == this) return 0;
         if (cc.Parent == null || cc.Parent == this)
            return cc.Left;
         else
            return leftA(cc.Parent) + cc.Left;
      }
      private void pictureBox1_MouseMove(object sender, MouseEventArgs e)
      {
         if (e.Button == MouseButtons.Left)
         {
            Top = MousePosition.Y - _mousePoint.Y;
            Left = MousePosition.X - _mousePoint.X;
         }
      }
      private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
      {
         Control cc = (Control)sender;
         if (e.Button == MouseButtons.Left)
         {
            _mousePoint.X = e.X + leftA(cc);
            _mousePoint.Y = e.Y + topA(cc);
         }
      }
