var  ReportList = (from l in ExampleTable.Enumerable()
                                                            where l["TEST_SET_IDENTIFICATION"] == testIdentificationList &&
                                                            l["SERIAL_NUMBER"] == serialList &&
                                                            l["DATA_WRITE_TIME"] == dateWriteTime &&
                                                            select l).ToList();
