如何使我的控制台应用程序在成功运行后自动重启？

Question

在用户选择选项后,如何使此程序继续运行？这是我到目前为止的代码.

using System.Text;

namespace calculator_extended

    class Program
    {
        static void Main(string[] args)

            Console.WriteLine("Press A for addition");
            Console.WriteLine("Press S for subtraction");
            Console.WriteLine("Press M for Multiplication");
            Console.WriteLine("Press D for Divide");

            char c = Convert.ToChar(Console.ReadLine());

            int a = Convert.ToInt32(Console.ReadLine());
            int b = Convert.ToInt32(Console.ReadLine());

            switch (c)
            {
                case 'A':
                case 'a':
                    {
                        int d = add(a, b);
                        Console.WriteLine(d);
                        break;


                    }


                case 'S':
                case 's':
                    {

                        Console.WriteLine(d);
                        break;
                    }

                case 'M':

                   return a - b;
    }
               private static int mul(int a, int b)

                   return a * b;
    }
               private static int div(int a, int b)
    {

                   return a / b;

        }
    }

用你的代码包装

while(true) {
    // Your code here

    // Don't forget to add a switch case for an Exit operation
    case 'q':
        Application.Exit();
}

如果你是编程新手,你应该研究循环 - 参见清单4-2 - 这是你想要完成的一个很好的例子.

编辑:我知道你是编程新手,我不认为你应该靠自己做到这一点.由于这是一个基本问题,这是一个完整的解决方案
