图片拖动问题

以前项目里面的例子

  static string strDown = @" AAACAAEAICAAAAsACQAwAQAAFgAAACgAAAAgAAAAQAAAAAEAAQAAAAAAAAIAAAAA

        Cursor curUp = new Cursor(new System.IO.MemoryStream(Convert.FromBase64String(strUp)));

        }

        private void pictureEdit1_MouseUp(object sender, MouseEventArgs e)

        }

        private void pictureEdit1_MouseMove(object sender, MouseEventArgs e)
        {
            if (bDragging)
            {
                Point oMoveToPoint;
                oMoveToPoint = this.PointToClient(pictureBox1.PointToScreen(new Point(e.X, e.Y)));

            }
        }

这些字符串是什么意思？
如果我想拖动不是图片，而是lable 用这种方法可以吗？

这些文字表示图片的二进制，他会将他们转为可用的格式

Cursor curUp = new Cursor(new System.IO.MemoryStream(Convert.FromBase64String(strUp))); Cursor curDown = new Cursor(new System.IO.MemoryStream(Convert.FromBase64String(strDown))); strup是base64编码过的byte数组。 我说这不是麻烦吗？为么不直接用byte[] ？

[winnowc]

strDown和strUp是两个鼠标的样式，相当于.cur格式的文件base64下。自己做拖动基本就是这个样子，MouseDown/MouseMove/MouseUp，只要和控件本身对鼠标事件的处理不冲突，都能这样拖。
