Question

我是c＃的初学者，我无法获得以下代码的输出。有人请帮帮我。运行代码时，结果未显示。我确定这里所犯的错误是非常愚蠢的，但我无法识别它。

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

namespace test2
{
    class Program
    {
        static void Main(string[] args)
        {
            float num, result;
            int opt;
            Console.Write("\t Enter your salary:");
            num = float.Parse(Console.ReadLine());
            Console.Write("\t Enter your option:");
            opt = Convert.ToInt32(Console.ReadLine());
            switch (opt)
            {
                case 1:
                    result = num * (5 / 100);
                    Console.Write("\t You have to pay the tax of rupees: {0}", result);
                    break;
                case 2:
                    result = num * (8 / 100);
                    Console.Write("\t You have to pay the tax of rupees: {0}", result);
                    break;
                case 3:
                    result = num * (5 / 100);
                    Console.Write("\t You have to pay the tax of rupees: {0}", result);
                    break;
                default:
                    Console.WriteLine("Invalid Option...Please try again.");
                    break;
            }
            Console.ReadLine();
        }
    }
}

尝试下面的代码，它的所有关于括号只是改变序列，你将得到我在VS 2012中尝试过的输出： -

        float num, result;
        int opt;
        Console.Write("\t Enter your salary:");
        num = float.Parse(Console.ReadLine());
        Console.Write("\t Enter your option:");
        opt = Convert.ToInt32(Console.ReadLine());
        switch (opt)
        {
            case 1:
                result = (num * 5) / 100;
                Console.Write("\t You have to pay the tax of rupees: {0}", result);
                break;
            case 2:
                result = (num * 8) / 100;
                Console.Write("\t You have to pay the tax of rupees: {0}", result);
                break;
            case 3:
                result = (num * 5) / 100;
                Console.Write("\t You have to pay the tax of rupees: {0}", result);
                break;
            default:
                Console.WriteLine("Invalid Option...Please try again.");
                break;
        }
        Console.ReadLine();
