我在计数器变量时遇到问题。每次离开每个方法时，count都会重新初始化为0.我还没有完成Stay()方法正在查杀Hit()方法。每次击中后我都需要显示所有用户的牌。我不知道该怎么做。必须有一种更有效的方式。我认为我的所有问题都来自Count变量的问题。
感谢您的帮助。 以下是我的主要课程。下面是我的Deck课程。 我遗漏了卡片，套装和等级课程。

答案 0 :(得分：0)
看看这段代码
public static int Hit(int count, int playerHand, Deck d)
{
count += 1;
您正在传递 count的副本并递增副本。您传入的原始值永远不会受到影响。直截了当的修复包括
ref int count传递次数。 更好的方法是将逻辑封装在类中，并使count成为该类的字段或属性，以便类方法可以查看和更改它。
