C# 当我不'；我不希望它出现在我的'；游戏选择'；程序

所以我再次陷入困境，我创建了一个“游戏选择”程序，允许用户选择他们的“技能”水平。我已经写了所有的代码，但是第24行的do循环引起了问题。当我选择高于4的技能等级或在“这是你想要的吗（y/n）”中键入“n”时，它将不会循环。代码如下：

class Program
{
    static void Main(string[] args)
    {
        string name;
        int one = 1, two = 2, three = 3, four = 4;
        int answer;
        int tripalarm = 0;
        string verification;



        Console.WriteLine("What is your name?");
        name = Convert.ToString(Console.ReadLine());

        Console.WriteLine(name + ", there are 4 skill levels in this game:");
        Console.WriteLine("1. Advanced" + Environment.NewLine + "2. Experienced" + Environment.NewLine + "3. Average" 
            + Environment.NewLine + "4. Novice");

        do
        {
            answer = 0;

            Console.WriteLine("Which skill level do you choose?");
            answer = Convert.ToInt32(Console.ReadLine());


            if (answer >= 5)
            {
                Console.WriteLine("Sorry " + name + " you should choose between 1 and 4:");
            }
            else if (answer <= 4)
            {
                if (answer == one)
                {
                    Console.WriteLine("Thank you " + name + ", you have choosen level one");
                    Console.WriteLine("Is this what you want? (y/n)");
                    verification = Convert.ToString(Console.ReadLine());
                    if (verification == "y")
                    {
                        Console.WriteLine("Good " + name + " you have chosen level one you can now start the game!");
                    }
                    else 
                    {
                        tripalarm++;
                    }
                }
                else if (answer == two)
                {
                    Console.WriteLine("Thank you " + name + ", you have choosen level two");
                    Console.WriteLine("Is this what you want? (y/n)");
                    verification = Convert.ToString(Console.ReadLine());
                    if (verification == "y")
                    {
                        Console.WriteLine("Good " + name + " you have chosen level two you can now start the game!");
                    }
                    else
                    {
                        tripalarm++;
                    }
                }
                else if (answer == three)
                {
                    Console.WriteLine("Thank you " + name + ", you have choosen level three");
                    Console.WriteLine("Is this what you want? (y/n)");
                    verification = Convert.ToString(Console.ReadLine());
                    if (verification == "y")
                    {
                        Console.WriteLine("Good " + name + " you have chosen level three you can now start the game!");
                    }
                    else
                    {
                        tripalarm++;
                    }
                }
                else if (answer == four)
                {
                    Console.WriteLine("Thank you " + name + ", you have choosen level four");
                    Console.WriteLine("Is this what you want? (y/n)");
                    verification = Convert.ToString(Console.ReadLine());
                    if (verification == "y")
                    {
                        Console.WriteLine("Good " + name + " you have chosen level four you can now start the game!");
                    }
                    else
                    {
                        tripalarm++;
                    }
                }

            }

        } while (tripalarm == 0);



    }
}

类程序
{
静态void Main（字符串[]参数）
{
字符串名；
int一=1，二=2，三=3，四=4；
int答案；
int tripalarm=0；
字符串验证；
你叫什么名字；
name=Convert.ToString（Console.ReadLine（））；
Console.WriteLine（name+），游戏中有4个技能等级：”；
Console.WriteLine（“1.高级”+Environment.NewLine+“2.经验丰富”+Environment.NewLine+“3.一般”
+Environment.NewLine+“4.新手”）；
做
{
答案=0；
Console.WriteLine（“您选择哪种技能级别？”）；
answer=Convert.ToInt32（Console.ReadLine（））；
如果（答案>=5）
{
WriteLine（“对不起”+name+”您应该在1和4之间选择：”；
}
else if（answer这将稍微简化您的代码，并应纠正错误：

static void Main(string[] args)
{
    var levelSelected = false;
    var answer = 0;

    Console.WriteLine("What is your name?");

    string name = Console.ReadLine();

    Console.WriteLine($"{name}, there are 4 skill levels in this game:");
    Console.WriteLine("1. Advanced");
    Console.WriteLine("2. Experienced");
    Console.WriteLine("3. Average");
    Console.WriteLine("4. Novice");

    while (!levelSelected)
    {
        Console.WriteLine("Which skill level do you choose?");
        answer = Convert.ToInt32(Console.ReadLine());

        switch (answer)
        {
            case 1:
            case 2:
            case 3:
            case 4:
                Console.WriteLine($"Thank you {name}, you have choosen level {answer}");
                Console.WriteLine("Is this what you want? (y/n)");
                levelSelected = Console.ReadLine() == "y";
                break;
            default:
                Console.WriteLine($"Sorry {name} you should choose between 1 and 4:");
                break;
        }
    }

    Console.WriteLine($"Good {name} you have chosen level {answer} you can now start the game!");         
    var x = Console.ReadLine();
}

注意，它仍然不会检查用户是否输入了级别的整数（如果他们不输入，则会导致错误），并且任何其他“y”都被视为“n”.
我尝试了几乎所有的事情
都在使用调试器—您尝试过什么？是的，它没有检测到任何错误。我建议使用Switch语句而不是else ifsYeah，这不是调试器所做的—它允许您在代码执行时观察代码，甚至与代码交互，以便您可以删除错误（因此得名为debug）好的，现在我来试试，谢谢。非常感谢，我现在了解了开关函数的工作原理。
