利用二维数组编写简单贪吃蛇小游戏，由于是初学C#，用的是单线程，所以蛇不会自动前进
代码及简要分析如下：
1 //定义地图,0为空，1为墙，2为蛇，3为食物
2 int[,] map = new int[15, 15]{
3 {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
4 {1,2,0,0,0,0,0,0,0,0,0,0,0,0,1},
5 {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
6 {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
7 {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
8 {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
9 {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
10 {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
11 {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
12 {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
13 {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
14 {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
15 {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
16 {1,0,0,0,0,0,0,0,0,0,0,0,0,0,1},
