Dim integers = {1, 2, 3, "a"}
        Dim characters = {"a", "b", "c", 1}
        Dim newArray As New ArrayList
        Dim count As Integer = 0
        For Each item In characters
            If Not newArray.Contains(item) Then
                newArray.Add(item)
                newArray.Add(integers(count))
                count += 1
            End If
        Next

        For Each item In newArray
            MsgBox(item)
        Next
