vb.net - multi-dimension array list

Question

I've managed to make some single dimension array lists but I can't figure out a multi dimension arraylist.

Here's what I'm trying to do:

I have a database (mdb) with 5 columns that I want each row to be in an array list.

In PHP what I'd typically do is:

$array[$field1] = array($field2,$field3,$field4,$field5);

How I do the same in vb.net so anytime I need to fetch an item for a specific for the row1 I could call it?

For a single dimension I could do the following, but I can't figure out how to add more fields to a single array row:

    Dim tmpArrayX As New ArrayList
    tmpArrayX.Add(field(0))
    tmpArrayX.Add(field(1))
    etc...

If you want to use ArrayList, just make it's items contain other ArrayLists.

Or you could use normal arrays as:

Dim multiArray(2, 2) As String
multiArray(0, 0) = "item1InRow1"
multiArray(0, 1) = "item2InRow1"
multiArray(1, 0) = "item1InRow2"
multiArray(1, 1) = "item2InRow2"

Though my personal preference would be to use List as:

Dim multiList As New List(Of List(Of String))
multiList.Add(New List(Of String))
multiList.Add(New List(Of String))

multiList(0).Add("item1InRow1")
multiList(0).Add("item2InRow1")
multiList(1).Add("item1InRow2")
multiList(1).Add("item2InRow2")

Edit: How to find row:

Dim listIWant As List(Of String) = Nothing
For Each l As List(Of String) In multiList
    If l.Contains("item1InRow2") Then
        listIWant = l
        Exit For
    End If
