例题：二维数组打印推箱子地图

   int[,] map = new int[10, 10]    //定义一个二维数组，十行十列

            {

                {1,1,1,1,1,1,1,1,1,1},

                {1,0,0,0,0,0,1,0,0,1},

                {1,0,2,0,0,0,1,0,0,1},

                {1,0,0,0,0,0,1,0,0,1},

                {1,0,0,0,0,0,0,1,0,1},

                {1,0,0,0,0,0,0,1,0,1},

                {1,0,0,1,0,0,0,0,0,1},

                {1,1,1,1,0,0,0,0,0,1},

                {1,0,0,0,8,0,0,0,9,1},

                {1,1,1,1,1,1,1,1,1,1},

            };

    for (int i = 0; i < 10; i++)
            {
                for (int j = 0; j < 10; j++)
                {
                    if (map[i, j] == 1)
                    {
                        Console.Write("□");//墙壁
                    }
                    else if (map[i, j] == 0)
                    {
                        Console.Write("  ");
                    }
                    else if (map[i, j] == 2)
                    {
                        Console.Write("○");//箱子
                    }
                    else if (map[i,j]==9)
                    {
                        Console.Write("★");//把箱子推到的位置
                    }
                    else if (map [i,j]==8)
                    {
                        Console.Write("人");
                    }/把地图显示出来
