新建
初始界面
在工具箱中找到 Timer，拖拽使用，将Name改为dt，Interval（单位：毫秒）改为500
Timer
然后编写代码
 string key_name = "start";   //记录键盘状态        Label[] l_b = new Label[30];   //贪吃蛇身体数组        Random r = new Random();    //随机数        int a = 0, b = 0;           //变量，记录坐标        public Form1()        {            InitializeComponent();
