C# if语句中的2个值不起作用-石头剪纸游戏C

因此，我陷入了一种困境，我无法使我的if语句正确工作，它们在屏幕上什么也不显示，有趣的是，当计算机和用户在石头-布-剪刀游戏中绘图时，只有最上面的if语句工作

以下是方法中无法正常工作的代码：

我尝试了不同的方法使“draw”一下面的if语句能够工作，方法是去掉两个“&&”，只使用一个。顺便说一下，这没有任何作用，我想不出任何其他方法来解决这个问题。

问题可能就在这里。您可以在Console.WriteLine中分配而不是连接

 if (playerChoice == STONE && compChoice == PAPER)
 {
     Console.WriteLine(name = "WINS AS STONE BEATS PAPER");
 }

但是通过一堆if语句来计算胜利者的想法通常是不好的

您从未设置字符串的值。 纸

也考虑使用枚举，如果在代码中使用其他，则 我们需要了解如何分配playerChoice和compChoice，以及纸/石头/剪刀的值。另外，如果玩家选择了他们不会输的石头，你需要显示代码，而不是描述它们。我无法通过电话游戏看出你的问题。你不需要发布全部代码，只需发布与你的问题相关的代码。尤其是竖起大拇指和微笑不太可能帮助任何人。@Himbrombere为自己说话，这让我很开心@泽山-诺恩疯了。供将来参考：虽然代码是一个问题，但它几乎肯定不是整个问题的原因。这可能只是许多问题中的一个。我对C允许赋值表达式感到惊讶和失望。它们是C/C++中经常出现错误的原因。@bufjape你还能怎么做a=b=C=5？我也解决了这个问题，非常感谢你给出的明确答案！虽然这可以通过调试来解决。。。为了扩展，您没有点击任何语句，因为您正在将播放器输入与其他内容进行比较。OK，我将更改此设置。谢谢您的帮助，现在可以使用了。不客气。但是看看另一个回答，因为它指出了另一个错误。
