private void Draw(Graphics graphics, Control control)        {            float X = float.Parse(control.Width.ToString()) - 1;            float Y = float.Parse(control.Height.ToString()) - 1;            PointF[] pointfs = {                new PointF(2,     0),                new PointF(X-2,   0),                new PointF(X-1,   1),                new PointF(X,     2),                new PointF(X,     Y-2),                new PointF(X-1,   Y-1),                new PointF(X-2,   Y),                new PointF(2,     Y),                new PointF(1,     Y-1),                new PointF(0,     Y-2),                new PointF(0,     2),                new PointF(1,     1)                };            GraphicsPath path = new GraphicsPath();            path.AddLines(pointfs);            Pen pen = new Pen(Color.FromArgb(150, Color.Blue), 1);            pen.DashStyle = DashStyle.Solid;            graphics.DrawPath(pen, path);        }

首先要把控件注册一个事件：控件名称.Paint+=事件名称,然后把以上函数进行传参，如：Draw(e.Graphics, this.control);
