增加一行：
DataTable measurements = new DataTable(); measurements.Columns.Add("StationTestName", typeof(string)); measurements.Columns.Add("SerialNumber", typeof(string)); measurements.Columns.Add("MeasurementName", typeof(string)); measurements.Columns.Add("Unit", typeof(string)); measurements.Columns.Add("Value", typeof(string)); measurements.Columns.Add("LowerLimit", typeof(string)); measurements.Columns.Add("UpperLimit", typeof(string)); measurements.Rows.Add( stationTestName, serialNumber, measurementSplits[0], measurementSplits[1], measurementSplits[2], measurementSplits[3], measurementSplits[4]);
取指定的其中一列的值：
datatable1.AsEnumerable().Select(r => r.Field<string>("Name")).ToArray();
datatable1.Rows.Cast<DataRow>().Select(r => r.ItemsArray[0].ToString())
