hello abdalla use following code: public static Tuple , double > GetAverageForMonth(List entries, int year, int month) { if (entries == null || entries.Count return null ; double Aveg = 0.0; var lst = entries.Where(s => s.dateTime.Year == year && s.dateTime.Month == year).ToList(); Aveg = lst.Sum(s=>s.Actual_mean_temp) / DateTime.DaysInMonth(year, month); return new Tuple }

There are two logic to get the number of days in any month and year. 1. No. of days = Row Count available in the table for that month and year 2. You can also get the number of days as shown below in C# int month; int year; int totalDays = DateTime.DaysInMonth(year, month);
