I have this two classes.
Public Class Class1
    Private names As List(Of String)
    Private _class2 As New Class2
    Public Sub AddName(ByVal name As String)
    End Sub
    Public ReadOnly Property AddAge(ByVal name As String) As Class2
            _class2.index = names.IndexOf(name)
            Return _class2
        End Get
    End Property
    Public Sub Clear()
    End Sub
    Public Class Class2
        Private _age As List(Of Integer)
        Protected Friend index As Integer
        Public Property Age() As Integer
                Return _age(index)
            End Get
            Set(ByVal value As Integer)
                _age(index) = value
            End Set
        End Property
        Public Sub Add()
        End Sub
        Public Sub Clear()
        End Sub
    End Class
End Class
How can I hide ,Sub Clear and Sub Add on class2, so they'll only be visible on
on Class1, like;
'This Sub is on Class1
Public Sub Clear()
    _class2.Clear() '<<<<<<<<<<
End Sub
I want they do not be visible on Sub Main(), like they are below.
Sub Main()
    Dim person As New Class1
                        'Those Subs (Clear an Add) are on Class2.
    person.AddAge("kid").Clear() '<<<<<<<<<<
    person.AddAge("kid").Add() '<<<<<<<<<<

End Sub
If I put Protected, class1 cannot access it. If I put Protected Friend, Sub Main() can still access them. Thanks for your help and time.

Used this from other forum:

Trust in .NET follows assembly boundaries. If you get two classes in one assembly then there are two programmers that know how to find each other if there's a problem. The only way to get what you want is to put these classes in a separate class library project. Which then lets you use Friend. And whomever writes that Main method doesn't have to be friendly.

I don't understand what is for class2 (as nested class). Can you explain it?
