Private Sub btnTest_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTest.Click
    Dim dt As New DataTable("Customers")
    dt.Columns.Add("firstname", System.Type.GetType("System.String"))
    dt.Columns.Add("lastname", System.Type.GetType("System.String"))
    dt.Columns.Add("department", System.Type.GetType("System.String"))
    dt.Columns.Add("email", System.Type.GetType("System.String"))
    dt.Columns.Add("phone", System.Type.GetType("System.String"))
    Dim oReader As New IO.StreamReader("C:\Customers.txt")
    Dim oCust As String
    Dim oData() As String
    Dim Index As Int32
    Dim drItem As DataRow
    Do
        oCust = oReader.ReadLine
        oData = oCust.Split(",".ToCharArray)
        For Index = oData.GetLowerBound(0) To oData.GetUpperBound(0)
            drItem = dt.NewRow
            drItem(Index) = oData(Index).ToString
            dt.Rows.Add(drItem)
            drItem = Nothing
        Next
    Loop Until oCust Is Nothing
End Sub

Hi, I have been playing with this but am getting the following error...

---------------------

An unhandled exception of type 'System.NullReferenceException' occurred in textfiletest.exe

Additional information: Object reference not set to an instance of an object.

---------------------

The line highlighted is "oData = oCust.Split(",".ToCharArray)"

I expect its something simple but what am I doing wrong?
