How to create an object with array

Dear Sergey: thanks for the reply. I'm sorry that my questions is not clear.

Let me try to explain better.

I easily can create a structure and use REDIM to create the required array:

Something like this:

Public Class clsBufferClass
Public Structure Traydef
Dim ChipSerialNumber() As String
End Structure
End class

DIM Buffer(10) As clsBufferClass.BufferDef

For intI As Integer = 0 To 10
Buffer(intI) = New clsBufferClass.BufferDef
'Reallocate storage space for tray array
ReDim Buffer(intI).Tray(10)
For intJ As Integer = 0 To 10
'Reallocate storage space for chips serial number
ReDim Buffer(intI).Tray(intJ).ChipSerialNumber(99)
Next intJ
Next intI


Now, I can easily reference to a given buffer (4), tray (10) and chip (99).

Buffer(4).Tray(10).Cell(99).SerialNumber

I would like to create something similar using classes. With a class I could for example use INotifyPropertyChanged.

Any ideas? Thank you.
