课后作业09 -- 定义一个三维数组并输出

            int[, ,] arr3 = new int[3, 2, 4] {{{1,2,3,4},{5,6,7,8}},
            {{9,10,11,12},{13,14,15,16}},{{17,18,19,20},{21,22,23,24}}};
            //使用foreach语句
            Console.WriteLine("使用foreach语句遍历数组：");
            foreach (int i in arr3)
                Console.Write(i + " ");
            //使用for循环
            Console.WriteLine("\n使用for循环遍历数组：");
            for (int i = 0; i < 3; i++)
            {
                for (int j = 0; j < 2; j++)
                {
                    for (int k = 0; k < 4; k++)
                    {
                        Console.Write(arr3[i, j, k] + " ");
                    }
                }
            }
            Console.ReadLine();
