I've created an object (called cMyBindingList) that inherits from
BindingList. I can serialize it and it's child items with no problem.
However, I've also created a public variable in cMyBindingList that I set
when I first create it. This variable, even though it is public, does not
serialize to the XML. What is the reason for this? Is it possible to do it?
TIA for any light you can shed. Here's the sample code (from a form with a
single button on it):

Imports System.ComponentModel

Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
        Dim oList1 As New cMyBindingList(15) '<-- note that iType is
specified
        For i As Integer = 1 To 5 'Load up list
            Dim oItem As New cMyItem
            oItem.Value1 = i.ToString
            oItem.Value2 = i.ToString
            oList1.Add(oItem)
        Next
        Dim oSerializer As New
Xml.Serialization.XmlSerializer(GetType(cMyBindingList))
        Dim myWriter As System.IO.StreamWriter = New
System.IO.StreamWriter("C:\MyTest.xml")
        oSerializer.Serialize(myWriter, oList1)
    End Sub
End Class

<Serializable()> <System.Runtime.InteropServices.ComVisible(False)> _
Public Class cMyBindingList
    Inherits BindingList(Of cMyItem)
    Public miMyType As Integer  '<-- THIS DOES NOT SERIALIZE!
    Public Sub New() 'this parameterless constructor required for
deserialization
    End Sub
    Public Sub New(ByVal iType As Integer)
        miMyType = iType
    End Sub
End Class

<Serializable()> <System.Runtime.InteropServices.ComVisible(False)> _
Public Class cMyItem
    Private msValue1 As String
    Private msValue2 As String
    Public Property Value1() As String
        Get
            Return msValue2
        End Get
        Set(ByVal value As String)
            msValue2 = value
        End Set
    End Property
    Public Property Value2() As String
        Get
            Return msValue1
        End Get
        Set(ByVal value As String)
            msValue1 = value
        End Set
    End Property
End Class

Hello Monty,

BindingList class will be serialized as an array, its properties won't be
serialized. You may create a new class, add all customized properties in
this class, and then and cMyBindingList as a property of this new class.

Thanks for the response. Are there any collection-type objects that will
serialize both public properties on the container and the object's child
items?

I have to say there is a limitation here. The work around is to create a
parent class and move all public properties into the parent class.
