运行 一段时间后,我的程序遇到了堆栈溢出问题。它在一段时间内工作正常,直到它不工作

My program runs into a Stack-overflow issue after some time of running. It works fine for sometime until it doesn't

我做了一个小的控制台 BlackJack 游戏。这是我使用 C# 开发的第一款游戏。游戏可以正常运行几轮,直到我收到“Whosebug”的错误消息。当我查看错误时,我发现在 DealerCardGenerator 和 PlayerCardGenerator 中变量“con”具有空值。我不明白这是为什么。任何帮助将不胜感激。

我不知道如何解决这个问题。

代码如下:

            int moneyRes = Convert.ToInt32(Console.ReadLine());

            playerMoney.TotalMoney += moneyRes;


            while (displayMenu)

您尝试使用 allCards 列表防止重复卡片的方式存在缺陷。一旦牌组用完,您的 PlayerCardGeneratorDealerCardGenerator 方法将无限递归。一般来说,这不是管理牌组的好方法(你最好将索引存储到牌中并洗牌数组以模仿洗牌),但无论哪种情况,你都需要决定 when/how 处理甲板清空。
