Question

Is there an easy way of comparing weeks in two dates like this…

var times = (from d in db.TimeSet
             where d.EventDate.Week) == DateTime.ThisWeek &&                         
             d.Employee.Username == username
             select d).ToList();

Answer 1

public static int GetWeekNumber(DateTime date)
{
        CultureInfo ci = CultureInfo.CurrentCulture;
        int weekNum = ci.Calendar.GetWeekOfYear(date, CalendarWeekRule.FirstFourDayWeek, DayOfWeek.Monday);
        return weekNum;
}

and

var times = (from d in db.TimeSet
             where GetWeekNumber(d.EventDate) == GetWeekNumber(DateTime.Now) &&                         
             d.Employee.Username == username
             select d).ToList();

You might want to look into CalendarWeekRule to pick the one that fits your needs.
