CSV2DataTable - Importing the data contained in a CSV file into a new DataTable

' Import the data contained in a CSV file into a new DataTable. By default the 
' values are Tab delimited, but you can use the second overload version to use 
' any other string you want.
' Example:
'    Dim table As DataTable = CSV2DataTable("D:\Users.txt")
'    DataGrid1.DataSource = table

Function CSV2DataTable(ByVal filename As String) As DataTable
    Return CSV2DataTable(filename, vbTab)
End Function
Function CSV2DataTable(ByVal filename As String, ByVal sepChar As String) As _
    Dim reader As System.IO.StreamReader
    Dim table As New DataTable
    Dim colAdded As Boolean = False

        ' open a reader for the input file, and read line by line
        reader = New System.IO.StreamReader(filename)
        Do While reader.Peek() >= 0
            ' read a line and split it into tokens, divided by the specified 
            ' separators
            Dim tokens As String() = System.Text.RegularExpressions.Regex.Split _
                (reader.ReadLine(), sepChar)
            ' add the columns if this is the first line
            If Not colAdded Then
                For Each token As String In tokens
                colAdded = True
                ' create a new empty row
                Dim row As DataRow = table.NewRow()
                ' fill the new row with the token extracted from the current 
                ' line
                For i As Integer = 0 To table.Columns.Count - 1
                    row(i) = tokens(i)
                ' add the row to the DataTable
            End If

        Return table
        If Not reader Is Nothing Then reader.Close()
    End Try
End Function
