如何在C#中实现赌场游戏循环运行并持续追踪资金变量？

嘿，作为刚入门C#的新手，你写的这个小赌场游戏已经有模有样啦！要实现循环玩游戏同时保留资金变量的需求，核心就是用循环结构把游戏的核心逻辑包起来，同时调整变量的作用域。我给你梳理下具体的优化方案：

核心思路

用while循环控制游戏流程：让游戏在满足条件（比如用户还有资金，或者用户选择继续玩）时重复运行
调整变量作用域：把money、Random对象这类需要跨轮次保留的变量放在循环外面
添加基础输入验证：避免用户输入非数字、超出范围的数值导致程序崩溃
优化变量命名：把ass、shit这类不规范的变量名改成有意义的名字，提升代码可读性

修改后的完整代码

// 游戏标题
Console.WriteLine("  ___         _          ");
Console.WriteLine(" / __|__ _ __(_)_ _  ___ ");
Console.WriteLine("| (__/ _` (_< | ' |/ _ | ");
Console.WriteLine("|_______,_/__/_|_||_|___/");

Random rnd = new Random();
int money = 10; // 初始资金，放在循环外保留值
bool isPlaying = true; // 控制游戏循环的开关

// 年龄验证只需要做一次，放在循环外
Console.WriteLine("Welcome");
Console.WriteLine("Please enter age");
int age = 0;
bool validAge = false;
// 验证年龄输入合法性
while (!validAge)
{
    string ageInput = Console.ReadLine();
    if (int.TryParse(ageInput, out age))
    {
        if (age >= 18)
        {
            validAge = true;
            Console.WriteLine("Age verified, let's play!");
        }
        else
        {
            Console.WriteLine("Please come back when you are 18.");
            return; // 年龄不够直接退出程序
        }
    }
    else
    {
        Console.WriteLine("Please enter a valid number for age.");
    }
}

// 游戏主循环：只要还有资金且用户想继续就玩
while (money > 0 && isPlaying)
{
    Console.WriteLine($"\nYou have {money} dollars.");
    Console.WriteLine("Please choose an integer 1-3:");
    
    int userGuess = 0;
    bool validGuess = false;
    // 验证用户数字选择的合法性
    while (!validGuess)
    {
        string guessInput = Console.ReadLine();
        if (int.TryParse(guessInput, out userGuess) && userGuess >=1 && userGuess <=3)
        {
            validGuess = true;
        }
        else
        {
            Console.WriteLine("Invalid input! Please enter an integer between 1-3.");
        }
    }

    // 处理下注金额
    int betAmount = 0;
    bool validBet = false;
    while (!validBet)
    {
        Console.WriteLine("How much would you like to bet?");
        string betInput = Console.ReadLine();
        if (int.TryParse(betInput, out betAmount))
        {
            if (betAmount > 0 && betAmount <= money)
            {
                validBet = true;
            }
            else if (betAmount <=0)
            {
                Console.WriteLine("Bet must be a positive number!");
            }
            else
            {
                Console.WriteLine($"You can't bet more than your current balance ({money} dollars)!");
            }
        }
        else
        {
            Console.WriteLine("Please enter a valid number for your bet.");
        }
    }

    // 生成随机数（每次循环重新生成）
    int randomNumber = rnd.Next(1, 4);
    Console.WriteLine("Spinning...");

    // 判断输赢并更新资金
    if (userGuess == randomNumber)
    {
        int winnings = betAmount * 3;
        money += winnings;
        Console.WriteLine($"You Win! You earned {winnings} dollars.");
        Console.WriteLine($"Your current balance is {money} dollars.");
    }
    else
    {
        money -= betAmount;
        Console.WriteLine($"You Lose! You lost {betAmount} dollars.");
        Console.WriteLine($"Your current balance is {money} dollars.");
    }
    Console.WriteLine($"The correct number was {randomNumber}");

    // 询问用户是否继续玩
    if (money > 0)
    {
        Console.WriteLine("\nWould you like to play again? (Y/N)");
        string continueInput = Console.ReadLine()?.Trim().ToUpper();
        isPlaying = continueInput == "Y";
    }
    else
    {
        Console.WriteLine("\nYou're out of money! Game over.");
    }
