c# - 程序不退出

Question

刚开始使用 C#，这可能只是一个简单的修复，但我似乎看不到它。一旦程序第一次执行(添加两个数字之后)，系统会提示用户输入是或否作为退出条件。当我输入“否”时，程序将再次循环。

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

namespace BasicCalculator
{
    class Program
    {
        static void Main(string[] args)
        {
            bool again = false;
            while (!again)
            {
                Console.WriteLine("C# Basic Calcuator");
                Console.WriteLine("Please enter two numbers to be added: ");
                Console.WriteLine("Number 1: ");

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


                Console.WriteLine("Number 2: ");
                int b = Convert.ToInt32(Console.ReadLine());

                Console.WriteLine("Result: ");
                result = a + b;

                //print result
                Console.WriteLine(result);

                //potential exit condition
                Console.WriteLine("Would you like to calculate again?");
                if(Console.ReadLine() == "no")
                {
                    again = false;
                }
                else
                {
                    again = true;
                }

            }



        }
    }
}

非常感谢任何帮助!

将前两行更改为以下内容:

bool again = true;
while (again)
