Import data from CSV to sqlserver with additional field

            <td><asp:FileUpload ID="JDE_CWR_FileUpload" runat="server" />
                                    <asp:Label ID="Label1" runat="server"></asp:Label></td></tr>

string fileExt = System.IO.Path.GetExtension(JDE_CWR_FileUpload.FileName);  //Get extension

                    if (fileExt == ".csv")   //check to see if its a .csv file

                        path = Server.MapPath("App_Data/upload/");
                        JDE_CWR_FileUpload.SaveAs(path + JDE_CWR_FileUpload.FileName);

                        DataTable sourceData = new DataTable();
                        using (OleDbConnection conn =
