MySQL でテーブルをセットアップし、サーバー エクスプローラーで接続を追加し、正しいアセンブリを追加し、適切な ADO.NET エンティティ モデルを作成し、正しい app.config ファイルを確保しました。データベースに保存するときに、次のコードを実行しています。
MySQLEntity MySQLDB= new MySQLEntity();
mysqlspectra DBSPectra = new mysqlspectra();
DBSPectra.DateTime = DateTime.Now;
DBSPectra.Name = null;
DBSPectra.Version = spectra.Info.Version;
DBSPectra.SerialHighNumber = spectra.Info.SerialHighNumber;
DBSPectra.SerialLowNumber = spectra.Info.SerialLowNumber;
DBSPectra.Completed = spectra.Info.Completed;
DBSPectra.SpectrometerID = spectra.Info.SpectrometerID;
DBSPectra.GasCellID = spectra.Info.GasCellID;
DBSPectra.Format = (short)spectra.Info.Format;
DBSPectra.Apodization = (short)spectra.Info.Apodization;
DBSPectra.PhaseApodization = (short)spectra.Info.PhaseApodization;
DBSPectra.Temperature = spectra.Info.Temperature;
DBSPectra.Pressure = spectra.Info.Pressure;
DBSPectra.NumScans = spectra.Info.NumScans;
DBSPectra.Resolution = spectra.Info.Resolution;
DBSPectra.Gain = spectra.Info.Gain;
DBSPectra.PathLength = spectra.Info.PathLength;
DBSPectra.FirstPoint = spectra.Info.FirstPoint;
DBSPectra.LastPoint = spectra.Info.LastPoint;
DBSPectra.MaxFrequency = spectra.Info.MaxFrequency;
DBSPectra.MaxLocPoint = spectra.Info.MaxLocPoint;
DBSPectra.MinLocPoint = spectra.Info.MinLocPoint;
DBSPectra.NumDataPoints = spectra.Info.NumDataPoints;
DBSPectra.NumDataPhase = spectra.Info.NumDataPhase;
DBSPectra.Step = spectra.Info.Step;
DBSPectra.IgramType = (short)spectra.Info.IgramType;
DBSPectra.DataPoints = GetBytes(spectra.DataPoints);
MySQLDB.mysqlspectras.AddObject(DBSPectra);
MySQLDB.SaveChanges();
