将一整数逆序，如987654321变为123456789。

        static void Main(string[] args)
        {

            int[] numbers = new int[] { 9, 8, 7, 6, 5, 4, 3, 2, 1 };
            for (int i = numbers.Length - 1; i >= 0; i--)
            {
                var dd = numbers[i];
                Console.WriteLine(dd);
            }

            int[] newArrary = numbers.Reverse().ToArray();

            foreach (var n in newArrary)
            {
                Console.WriteLine(n);
            }
            Console.ReadLine();
        }
