c#程序控制台一个整数。在逆序输出!如123,输出则是321!写的越简单越好,一看就懂

   程序代码:
程序代码:    class Program
    {
        static void Main(string[] args)
        {
            int a = 123;
            int b = 0;
            while (a > 0)
            {
                b = b * 10 + a % 10;
                a /= 10;
            }
            Console.WriteLine(b);
        }
    }

 程序代码:
程序代码:using System;
using System.Collections.Generic;
class Program
{
    static void Main(string[] args)
    {
        int a = 1234567;
        char[] b = a.ToString().ToCharArray();
        Array.Reverse(b);
        string c = new string(b);
        Console.WriteLine(c);
    }
}
如果不知道Array.Reverse()的用法,那么还可以这么做 程序代码:
程序代码:using System;
class Program
{
    static void Main(string[] args)
    {
        int a = 1234567;
        char[] b = a.ToString().ToCharArray();
        int c = b.Length / 2;
        for (int i = 0; i < c; i++)
        {
            char tmp = b[i];
            int d = b.Length - i - 1;
            b[i] = b[d];
            b[d] = tmp;
        }
        string e = new string(b);
        Console.WriteLine(e);
    }
}
