[2005] loop through arraylist [resolved]

[texas]

this should be simple enough... what is the correct way to loop through an arraylist?

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim CorpGroups As ArrayList = Groups.GetGroupNums

        PrintValues(CorpGroups)

        With Me.DataGridView1
            .DataSource = CorpGroups
        End With

    End Sub

    Public Shared Sub PrintValues(ByVal myList As IEnumerable)
        Dim myEnumerator As System.Collections.IEnumerator = myList.GetEnumerator()

        While myEnumerator.MoveNext()
            Console.Write(ControlChars.Tab + "{0}", myEnumerator.Current)
        End While

        Console.WriteLine()

    End Sub

Console.Write outputs this:
GroupReportsFolderCreator.Groups

but the GridView has the correct info:

corp_num  group_num
123            1586
123            1587
