求解控制台的输入一个整数，再以倒数输出

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Please input a number:");
            try
            {

                Single s = Convert.ToSingle(Console.ReadLine());
                Console.WriteLine("The output should be:1/" + s);
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
            Console.ReadLine();
        }
    }
}
仅供参考

谢谢！！
