Regarding the Hashtable class, ht.Items.Add(x)

Public ReadOnly Property Items As ListItemCollection

What is the relationship between the above property and the public class ListItemCollection.
The below code is a simple class using a property to access another.
ca.Items.Add - Does this create a new instance of ClassB wihtin ClassA, I'm not sure
because with the HashTable class "Items" is a property and "Add" is a method of the type that Items refers to. The relation to HashTable is I have a dropdownlist control called c1. Now the statement c1.Items.Add(listItem) called X times. Wouldn't an instance of ListItemCollection be associated with dropdownlist c1.

Thanks.


<script runat="server">



  Public Class ClassB



    private count As Integer = 0



    Sub Add()

      count = count + 1

    End Sub



    Function getCount

      return count

    End Function



  End Class



  Public class ClassA



    Public ReadOnly Property Counter As ClassB

      Get

        return new ClassB

      End Get

    End Property



  End Class



  Sub Page_Load

    Dim ca As New ClassA

    ca.Counter.Add

    Response.Write(ca.Counter.getCount)

  End Sub
