我尝试过：

I need when the ball passes from the board then show a defeat`Game Over.I don't know how to write that code.Please help me.
Thanks.

What I have tried:

class Ball
    {
        public int x;
        public int y;
        public int vx = 3;
        public int vy = 3;
        public int r;
        public Graphics gf;
        public Game game;
        public SolidBrush myColor;
        public Ball(int x,int y,int vx,int vy,int r,Graphics gf,Game game) 
        {
            this.x = x;
            this.y = y;
            this.vx = vx;
            this.vy = vy;
            this.r = r;
            this.gf = gf;
            this.game = game;
            myColor = new SolidBrush(Color.IndianRed);
        }
        public void Draw()
        {
            this.gf.FillEllipse(myColor, x, y, r, r);
        }
        public void Move()
        {
            this.x += this.vx;
            this.y += this.vy;

                SolidBrush guyn = new SolidBrush(Color.FromArgb(255, r, g, b));
                this.myColor = guyn;

这看起来有点陈旧，但是也许它对你有用：如何建立一个具有动画和声音的突破风格游戏。 [ ^ ]

另请参阅此处的答案：制作突破游戏 [ ^ ]



你知道 board.w 和 board.h ，所以只需检查球的位置是否大于这些值。还要检查球的位置是否小于 board.x 和 board.y 。



如果你想要一个'游戏结束'屏幕，那么只需创建一个新表格并将背景图像属性设置为图片，这可以是.jpg，.gif或.png图像。

请参阅： Control.BackgroundImage属性（System.Windows.Forms） [ ^ ]

This looks a bit dated, but maybe it will be useful to you: How to build a breakout style game with animation and sound.[^]
Also see the answer here: Making breakout game[^]

You know the board.w and board.h, so simply check if the ball position is greater than these values. Also check if the ball position is less than board.x and board.y.

If you want a 'Game Over' screen, then just create a new Form and set the background image property to a picture, this can be a .jpg, .gif or .png image.
