I'm still learning VB.net and I struggle with it a lot

I have done my assignment that is due Wednesday, but I there is a bit of code I have added which is an array and I want to add a list of items to the array. If that makes sense.

I have 6 classes two have arrays.

Here is the code from one of the classes

Public Function getItems() As Array
Return _LevelItems
End Function

How would I add the item list to this?
Where do I put it? Like underneath it or in the items class? That code is in the Level class.

Thanks
