以前一直都是在做MFC（俺一直都是做DSP软件的，PC上跟DSP通讯等程序一直都是用MFC做的）,最近在看C#方面的东西，感觉C#挺方便的，于是便随便写了这么个小游戏，里面主要是Timer的应用、delegate的应用和Graphics的应用等，原理很简单，操作也很简单（键盘操作用左、右键，鼠标操作只是左右操作就可以了），特此分享一下，有兴趣的可以一起探讨一下。程序的运行画面如下：          程序的主要数据结构如下：    （1）球体的数据结构 public struct Ball
        {
            public Point TopPoint;      //最上面坐标
            public Point BottomPoint;   //最下面坐标
            public Point LeftPoint;     //最左边坐标
            public Point RightPoint;    //最右边坐标
            public Brush BallBrush;     //球体颜 {MOD}
            public bool IsPassed;       //是否已经miss             //下降一次
            public void FollowOneStep(int nOneStep,ref int missBalls)
            {
                TopPoint.Y += nOneStep;
                BottomPoint.Y += nOneStep;
                LeftPoint.Y += nOneStep;
                RightPoint.Y += nOneStep;                 if (BottomPoint.Y >= MONITOR_BOTTOM_EDGE)
                {
                    IsPassed = true;                     missBalls++;
                }
            }             //检测球体是不是被平衡木触摸到,接触到则将IsPassed职位TRUE
            public bool CheckBallsPassState(Point topLeftPointOfBeam,ref int recvBalls)
            {
                if (BottomPoint.Y > topLeftPointOfBeam.Y && TopPoint.Y < topLeftPointOfBeam.Y + BEAM_WIDTH) //球体在平衡木可接触的水平线上
                {
                    if (RightPoint.X > topLeftPointOfBeam.X && LeftPoint.X < topLeftPointOfBeam.X + BEAM_LENGH)                       
                    {
                        IsPassed = true;                         recvBalls++;
                    }                   
                }                 return IsPassed;
            }
        }   （2）游戏难度数据结构    public struct DegreeOfDifcuty
        {
            public int Diffcuty;              //难度
            public int FollowOneTime;         //一次下降的像素点
            public int AddOneBallOfBreak;     //多少ms添加一个球
            public int FollowOfBreak;         //多少个Timer中断产生一次下降事件
