从窗体C#的边缘反弹

我目前正在尝试让3个球在表单中反弹并使其工作，问题是我的代码的这一部分（使球从表单的边缘反弹）看起来非常笨拙，我觉得它可以以某种方式浓缩。有什么方法可以清理吗

public void Move(int width, int height)
        {
            if ((position.X >= 0) && (position.X + size <= width)) //Within X Bounds
            {
                if (XBounce)
                {
                    position.X -= speed;
                }
                else
                {
                    position.X += speed;
                }
            }
            else
            {
                if (!XBounce)
                {
                    position.X -= size / 2;
                }
                else
                {
                    position.X += size / 2;
                }
                XBounce = !XBounce;
            }
            if ((position.Y >= 0) && (position.Y + size <= height)) //Within Y Bounds
            {
                if (YBounce)
                {
                    position.Y -= speed;
                }
                else
                {
                    position.Y += speed;
                }
            }
            else
            {
                if (!YBounce)
                {
                    position.Y -= size / 2;
                }
                else
                {
                    position.Y += size / 2;
                }
                YBounce = !YBounce;
            }
        }

public void Move(int width, int height)
    {
        if ((position.X >= 0) && (position.X + size <= width)) //Within X Bounds
        {
            position.X -= XBounce * speed;
        }
        else
        {
            XBounce = -XBounce;
            position.X -= XBounce * size / 2;
        }
        if ((position.Y >= 0) && (position.Y + size <= height)) //Within Y Bounds
        {
                position.Y -= YBounce * speed;
        }
        else
        {
            YBounce = -YBounce;
            position.Y -= YBounce * size / 2;
        }
    }
