Question

尝试制作一个简单的应用程序，它将询问一些问题。但是由于某种原因，我的AskQuestion函数不起作用。我计划以后再添加一个易于交换的数据库，这就是为什么我尝试采用稍微模块化的方法的原因，并且由于我是初学者，所以我不确定自己做错了什么。唯一的错误是AskQuestion类的第21行。

错误是：

期望使用CS1001标识符

CS1514 {预期

CS1513}预期

Answer 1

更改此

class void AskQuestion(Question Q)

到

void AskQuestion(Question Q)

这应该是一种方法。关键字class告诉编译器您要在out类Program

中创建一个内部类

Answer 2

Q.givenanswer.ToLower();不会使Q.givenanswer小写-它返回一个新的小写字符串，您需要将其分配给变量，或者只是`Q.givenanswer = Q.givenanswer.ToLower（）; < / p>

未知原因的预期C＃标识符
