Question

由于历史原因，我们需要通过COM接口公开.NET中的字符串常量。

我们设法暴露了ENUM，但我们找不到公开字符串const的方法。

我们尝试以下代码：

<ComClass(ComClass1.ClassId, ComClass1.InterfaceId, ComClass1.EventsId)> _
Public Class ComClass1

#Region "COM GUIDs"
    ' These  GUIDs provide the COM identity for this class 
    ' and its COM interfaces. If you change them, existing 
    ' clients will no longer be able to access the class.
    Public Const ClassId As String = "608c6545-977e-4260-a3cf-11545c82906a"
    Public Const InterfaceId As String = "12b8a6c7-e7f6-4022-becd-2efd8b3a756e"
    Public Const EventsId As String = "05a2856f-d877-4673-8ea8-20f5a9f268d5"
#End Region

    ' A creatable COM class must have a Public Sub New() 
    ' with no parameters, otherwise, the class will not be 
    ' registered in the COM registry and cannot be created 
    ' via CreateObject.
    Public Sub New()
        MyBase.New()
    End Sub

    Public Const chaine As String = "TEST"

    Public Sub Method()

    End Sub

End Class

但是当我们查看OLE对象查看器时，我们只看到该方法。

有人有想法吗？

谢谢，

如果你遇到常量问题，你总是可以声明一个只读的getter来返回每个常量。
