Here's some VB.NET based on one of those C# examples.
ParseCSV is a test driver.
ParseLine is the routine you'd actually want to use.

    Private Shared Sub ParseCSV()
        Dim oneLine As String = _
        """quoted"",nonquoted,""comma, """"inner-quoted-comma"""", chamelean"",,after-empty"

        Dim fieldValues As String() = ParseLine(oneLine)

        For i As Integer = 0 To fieldValues.Length - 1
            Console.WriteLine(i & "  [" & fieldValues(i) & "]")
        Next
    End Sub

    Private Shared Function ParseLine(ByVal oneLine As String) As String()
        ' Returns an array containing the values of the comma-separated fields.

        ' This pattern actually recognizes the correct commas.
        ' The Regex.Split() command later gets text between the commas.
        Dim pattern As String = ",(?=(?:[^""]*""[^""]*"")*(?![^""]*""))"
        Dim r As System.Text.RegularExpressions.Regex = _
                New System.Text.RegularExpressions.Regex(pattern)

        Return r.Split(oneLine)
    End Function

Correct output:
0  ["quoted"]
1  [nonquoted]
2  ["comma, ""inner-quoted-comma"", chamelean"]
3  []
4  [after-empty]

Here's another post about multidimensional arrays -- already answered.

Here's some good stuff, especially near the bottom.

Here's a sample program for two-dimensional arrays.
Near the bottom, there's a link to a very good PowerPoint presentation, too.  Chapter8.ppt
