“我有一个代码,但出现了错误(在标题中说明)
Module Module1
Dim direction As String = ""
Sub Main()
Console.WriteLine("As you step into the dugeon you realise you are stuck. At the end of the path it converges into 3 paths.")
While direction <> "Left" And direction <> "right" And direction <> "Middle"
*direction = Console.WriteLine("Do you want to go left, right, or straight up?")*
End While
Console.ReadLine()
End Sub
End Module
你知道我可以解决它吗?它之间有星星的代码是不起作用的,所以我只需要正确的代码作为答案,然后我就可以为它欢呼。
答案 0 :(得分:0)
direction = Console.WriteLine(..)
没有意义:写!=阅读。
错误是因为WriteLine
有一个 void 结果类型,“不是一个值”。 void type表示没有任何值,不能用于表达式(包括赋值)。
代码应该使用WriteLine
显示文本,然后使用ReadLine
来返回字符串,以读取一些输入。还要考虑规范化输入(例如,在读取字符串上使用ToLower/Trim
)并匹配条件检查中使用的大小写。
