解析C#中如何把控件的边框角画为圆弧

以下是对C#中把控件的边框角画为圆弧的实现代码进行了介绍，需要的朋友可以参考下
 
复制代码 代码如下:

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);
