List (of T) Works in VS2005 but not in VS2003

I have an application that runs on Compact Framework (VB.NET) developed under visual studio 2005 (CF2). I have a requirement to recompile this code using visual studio 2003 (CF1.1)  however the List (of T) (from  System.Collections.Generic List(T) Class) command is not supported. Is there an equivalent syntax/command I can use for an array of objects. (The code that fails is enclosed : Public items As List(Of Item)) - Many thanks.
Public Class item

    Public uid As String

    Public suspend As String

    Public success As String

    Public msg_text As String

    Public msg_result As String
 

    Public result_selcted As Boolean
 

    Public Sub New()

        uid = ""

        suspend = ""

        success = ""

        msg_text = ""

        msg_result = ""

    End Sub

End Class
 

Public Class question

    Public dbref As String

    Public uid As String

    Public type As String

    Public suspend As String

    Public success As String

    Public items As List(Of Item)
 

    Public Sub New()

        dbref = ""

        uid = ""

        type = ""

        suspend = ""

        success = ""

        items = New List(Of item)

    End Sub

End Class

Open in new window

this feature is called Generics and was new in VS2005.

you will need to remove the (of T) but you will loose all type checking at the same time.

Many thanks for help so far - List on it's own does not appear to be supported either.... (Type 'List' is not defined') I can define it as an array but would I still be able to store an object in it? (Part of the application havily depends on being able to address each object / properties)

In VB.Net 2003 (and below) an ArrayList would suffice:

you could use a Array or a Collection (it would be better since less modification would be required)

Have opted for the Collection and I am using CType to use type checking. Many thanks for all your help.
