Question

所以我正在写一些卡片游戏来学习一些C＃。这是我的第一个项目，我遇到了一些麻烦。所以游戏只会问你一些简单的问题。下一张卡是红色还是黑色，是下一张卡高于或低于前一张卡，以及下一张卡在前两张卡的内部或外部。最后，为下一张卡挑选一套西装。它的全部工作除了in out部分。我正在使用switch语句来获取userinput，然后使用if语句来提出正确的答案。如果你打开“in”它会完美运行但如果你输入“out”则不正确请帮助。此外，任何批评都会很好。谢谢你的帮助。

Answer 1

在确定卡是否在“范围之外”时，您的问题似乎与您的逻辑有关。目前，您的内部if语句基本上说：“如果卡片小于较小的卡且大于较大的卡片”，这显然是不可能的，而是您想要断言使用布尔OR（||）运算符，该卡小于较大的卡或大于较大的卡：

...
if (rorbcard.CardNumber > highLow.CardNumber)
{
    if (inOut.CardNumber > rorbcard.CardNumber) || (inOut.CardNumber < highLow.CardNumber)
    {
        Console.WriteLine("Correct give 6 drinks\n");
    }
    else
    {
        Console.WriteLine("Wrong take 6 drinks\n");
    }
}
else if (rorbcard.CardNumber < highLow.CardNumber)
{
    if (inOut.CardNumber < rorbcard.CardNumber) || (inOut.CardNumber > highLow.CardNumber)
    {
        Console.WriteLine("Correct give 6 drinks\n");
    }
    else
    {
        Console.WriteLine("Wrong take 6 drinks\n");
    }
}
break;
...

请注意，正如其他人所提到的，当AND或OR的两边都是bool类型时，您应该使用条件运算符&&和||，而不是逻辑{{ 1}}和&。

Answer 2

我注意到你的情况下有更多的括号。这可能会改变代码的行为。

纸牌游戏，为什么switch语句的一部分工作而另一部分没有？
