Store multiple values into an Array

Hello,
How do you efficiently store and fetch data properties that is stored in an Array?
Public Function Customers() As IList
        Dim cust = _dataNorthwind.Customers
        Dim latt As New ArrayList()

        For Each vlist In cust
            latt.Add(vlist.CustomerId) 'how to store multiple properties here then fetch those?
        Next

        Return latt.ToArray
    End Function
