How to pass a variable (string array) to nested classes?

I have an inner class that needs a variable from an upper class.  The variable is actually a string array.  I tried using Friend believing that it would make the variable available to the nested classes below the class that I used it in.  This did not work.  So I created a property to pass the variable but I am convinced that there must be a way to do this without writing a property to pass this variable for every nested class its needed.

You can pass it into inner class in the constructor.

Can you provide the structure of your parent and child classes?

Thanks for your time.  I should have included this in my first post.  

Public Class OneClass
    Private _Equation As String
    Private equ() As String

    Public Function Start(ByVal Equation As String) As ArrayList
        _Equation = Equation
        equ = _Equation.Split("=") 'splits the equation into right and left expressions.
    End Function
End Class

Class AnotherClass
    Friend Property A As Array
        Get
            Return equ
        End Get
        Set(value As Array)
            equ = value
        End Set
    End Property

    Private ReadOnly Property B As String
        Get
            Return equ(0)
        End Get
    End Property

    Private ReadOnly Property C As String
        Get
            Return equ(1)
        End Get
    End Property

    Class Simplify
        Public ReadOnly Property D() As ArrayList
            Get
                Return equ(0)
            End Get
        End Property

        Public ReadOnly Property E() As ArrayList
            Get
                Return equ(1)
            End Get
        End Property
    End Class
End Class

Will arraylist work for you?

NevSoFlyAuthor Commented:
It would work.  I just thought it was easier to do a simple array as it was all I needed.

Actually, Arraylist are so simple and ease of use.

Dim ar as New ArrayList
ar.Add("1")
ar.Add("2")

Using a loop, you can load a list inside, and you can identify them by index.

Exactly how would this help my original problem?

Maybe it would help if I restated my desire.

I have an outer class with a variable (Private equ() as string) that I want to make available to inner classes (somestring = equ(0)).  I have tried private, public, shared and friend, all give me the error "'equ' is not declared. It may be inaccessible due to its protection level.".  

I have also included the  outer class when calling the variable (Outerclass.equ(0)).  This gives me the error "'equ' is not a member of 'WindowsApplication1.Expression'.".

Would a Structure work better?

I'm obviously missing something very basic.  Non of my searches has given me a glue as to how to fix it.

Please help.

I would prefer not to do it that way but it could work for some instances.
