    Dim top As TreeNode
    Dim nod As TreeNode
    For Each top In tree.Nodes
        queue.Enqueue(top)
    Next
    While (queue.Count > 0)
        top = queue.Dequeue
        nodes.Add(top)
        For Each nod In top.Nodes
            queue.Enqueue(nod)
        Next
    End While
    FlattenBreadth = nodes
End Function
