I have these two classes as a test, one inherited by the other. The real code that the test is based on is a DLL so I don’t want to expose every property to the users of the DLL. I would like to be able to access the child’s properties from the parent via reflection.

Public Module App
  Public Sub Main()
    Dim child As New ChildClass()
    child.Run()
  End Sub
End Module

Public MustInherit Class ParentClass
  Public Sub Run()
    [GetType].GetProperty("ProtectedProperty").GetValue(Me).ToString()
    [GetType].GetProperty("ProtectedFriendProperty").GetValue(Me).ToString()
    [GetType].GetProperty("FriendProperty").GetValue(Me).ToString()
    [GetType].GetProperty("PublicProperty").GetValue(Me).ToString()
    End
  End Sub
End Class

Public Class ChildClass
  Inherits ParentClass
  Protected Property ProtectedProperty As String = "Protected"
  Protected Friend Property ProtectedFriendProperty As String = "ProtectedFriend"
  Friend Property FriendProperty As String = "Friend"
  Public Property PublicProperty As String = "Public"
End Class

I would have expected any of the Friend properties to be accessible from the parent, but only the Public property doesn’t throw an error. Is there something I’m missing?
