Question

How do I write the where statement that select records with Date field between Sunday to Saturday of a given date.

Data Fields: Id, Name, Date

Answer 1

Where date is the date in question, how about:

    DateTime start = date.Date.AddDays(-(int)date.DayOfWeek), // prev sunday 00:00
        end = start.AddDays(7); // next sunday 00:00

    var qry = from record in data
              where record.Date >= start // include start
               && record.Date < end // exclude end
              select record;
