Guardar txt modificado en un datagridview

[karlosc]

Buenas noches, alguna idea de como guardar un txt modificado en datagridview.
Private Sub CargarToolStripMenuItem_Click(sender As System.Object, e As System.EventArgs) Handles CargarToolStripMenuItem.Click

Try
If (CargarToolStripMenuItem.Text <> String.Empty) Then

Dim leer As New StreamReader("d:\Archivos de programa\arroz\especial.dat")

Dim texto As String = ""

Dim count As Integer = 25

Dim split As String() = Nothing

While (Not texto Is Nothing)

texto = leer.ReadLine
If (Not texto Is Nothing) Then

split = texto.Split(New Char() {CChar("'"), CChar(":"), CChar(";")}, count)

DataGridView1.Rows.Add(split(1), split(1), split(2), split(3), split(4), split(5), split(6), split(7), split(8), split(9), split(10), split(11), split(12), split(13), split(14), split(15), split(16), split(17), split(18), split(19), split(20), split(21), split(22), split(23))

End If

End While
Else

MsgBox("Seleccione el archivo a cargar", MsgBoxStyle.Exclamation, "Error")

End If
Catch ex As Exception

MsgBox(ex.Message)

End Try
End Sub
