C＃Casino Program Homework

Question

下面列出的是我的程序。我应该拿两张经销商和玩家的牌，并评估谁拥有更高的牌。玩家在该赌注下投注一定数量的现金，当然，如果他赢了他赢了赌注，如果他输了，他就会丢失现金。我似乎正确地遵循了伪代码，但我一直收到错误。有人想引导我做错的事吗？请谢谢你的回复。错误后面是代码。

我将您的代码复制并粘贴到Visual Studio中。

在您担心{括号语法错误之前，您需要考虑并修复：

• 布尔更多=“是”; （没有意义）
• 随机r = new Random（）; （已经定义）
• 在DisplayCard（）中返回卡，因为它是一个无效函数
• 在Evaluate（）
