Question

所以当我的答案在TextValidation上是错误的时例如，TextValidation值=“寓言”将不起作用，并且当TextValidation值不在“寓言”中或其他任何情况下均不会发生。我试图删除语句上的else，并且TextValidation value =“ fable”再次起作用。我不知道我的代码T_T有什么问题。

public TextMeshProUGUI TextValidation;
string[] rightanswers = { "able", "alef", "bale", "blae", "feal", 
    "flab", "flea", "leaf", "fable" };

public void rightanswersButton()
{
    for (int index = 0; index < rightanswers.Length; index++)
    {
        if (finalAnswer == rightanswers[index])
        {        
            TextValidation.text = "You are correct your answer is :" + finalAnswer;
            delete();
        }
        else
        {
            TextValidation.text = "You are wrong";
            delete();
        }
    }
}

您只关心数组中是否存在用户的值，但是您正在检查每个值，因此最终将找到最多一个正确的答案和一堆错误的答案，然后打印淘汰了大量不必要的消息。

有几种方法可以解决这个问题。例如，如果找到一个值，则可以设置一个标志并尽早退出循环。

bool isFound = false;
for (int index = 0; index < rightanswers.Length; index++)
{
    if (finalAnswer == rightanswers[index])
    {        
        isFound = true;
        break;
    }
}

if (isFound)
    TextValidation.text = "You are correct your answer is :" + finalAnswer;
else
    TextValidation.text = "You are wrong";
delete();

或者，您可以使用LINQ来查找数组中的任何元素是否与您要查找的值匹配。

if (rightanswers.Any(x => x == finalAnswer))
    TextValidation.text = "You are correct your answer is :" + finalAnswer;
else
    TextValidation.text = "You are wrong";
delete();
