SampleIndoorStation samplesIndoorStation = new SampleIndoorStation();??????????? samplesIndoorStation = SamplesIndoorStationTranslater.SampleCheckInfoShowGridVOToSampleIndoor(sampleCheckInfoShowGrid, Database);??????????? samplesIndoorStation.Save(Database); var responsetemp = Database.SampleIndoorStations.First(p => p.ID == samplesIndoorStation.ID);服務(wù)器端我想先保存，然后再更新該數(shù)據(jù)的時間戳返回給客戶端，以此控制并發(fā)，可是為什么再查的數(shù)據(jù)時間戳沒有改變？是Database沒有與數(shù)據(jù)庫中的數(shù)據(jù)同步嗎？該怎么辦？
