.net - 字符串数组需要声明吗？

Question

我在这个简单的代码中遇到了以下问题:

Public Class BookStoreDatabase

Public publicationArray(0 To 3) As String

publicationArray(0) = "Stories to Scare People With"
End Class

“publicationArray(0) 等”位告诉我需要声明“publicationArray”。这似乎不应该发生。

Answer 1

您不能在Class级别分配数组元素。如果您需要在 BookStoreDatabase 类本身实例化后立即对其进行赋值，则必须使用构造函数:

Public Class BookStoreDatabase

    Public Sub New()
        publicationArray(0) = "Stories to Scare People With"
    End Sub

    Public publicationArray(0 To 3) As String

End Class
