array of objects

Why won't this work?

VB Code:

<Serializable()> Friend Class ExportObject
    Friend Groups() As [b]New[/b] Group
 
    Friend Class Group
        Friend GroupName As String
        Friend Members() As Member
 
        Friend Sub AddMember(ByVal Name As String, ByVal ID As String)
            'make the members object array big enough
            ReDim Members(Members.GetUpperBound(0) + 1)
 
            Members(Members.GetUpperBound(0)).MemberName = Name
            Members(Members.GetUpperBound(0)).MemberID = ID
        End Sub
    End Class
 
    Friend Class Member
        Friend MemberName As String
        Friend MemberID As String
    End Class
 
    Friend Sub AddGroup(ByVal GroupName As String)
        Try
            'resize the group object array
            ReDim Groups(Groups.GetUpperBound(0) + 1)
            Groups(Groups.GetUpperBound(0)).GroupName = GroupName
        Catch ex As System.NullReferenceException
            'if this happens, the group object has not yet been initialized
            ReDim Groups(0)
            Groups(0).GroupName = GroupName
        End Try
    End Sub
End Class

It tells me that arrays can not be declared using "new"

How am I supposed to make an object array from one of my classes?

Thanks in advance,

You will have to loop through each element and instantiate it.

And how do I do this if I do not know how many groups I will be creating?

Is there a way to create the element and instantiate it at the same time?

I would suggest that you use a collection class of some sort when you have an unknown number of elements.

Then you would just instantiate the element as you are adding it (or you can, anyway)

VB Code:

MyGroupCollection.Add(New Group())

So I have to define the group as being a collection?

Could you demonstrate this for me... I'm not quite following what it is that you're trying to convey to me.

....

use the code I posted if you want... nothing fancy, just to give me an idea of what I need to do

Thanks again,
