示例1: GetFittedMeasurements

		private static Task<IEnumerable<Measurement>> GetFittedMeasurements(
			DataConnection Connection, int SensorId, DateTime StartTime, DateTime EndTime,
			int MaxMeasurementCount)
		{
			if (EndTime < StartTime)
				throw new ArgumentException($"{nameof(StartTime)} was greater than {nameof(EndTime)}");

			var timeSpan = EndTime - StartTime;
			if (timeSpan.TotalMinutes <= MaxMeasurementCount)
			{
				// Assume that one measurement was made per minute.
				// This assumption may not _always_ prove to be correct,
				// but we'd like to keep database chatter to a minimum.
				return Connection.GetMeasurementsAsync(SensorId, StartTime, EndTime);
			}
			else if (timeSpan.TotalHours <= MaxMeasurementCount)
			{
				return Connection.GetHourAveragesAsync(
					SensorId, MeasurementAggregation.Quantize(StartTime, TimeSpan.FromHours(1)),
