How to get the date of the next Sunday? [duplicate]

Answer 1

        var date = DateTime.Now;
        var nextSunday = date.AddDays(7 - (int) date.DayOfWeek);    

If you need nearest sunday, code little bit different (as if you're on sunday, nearest sunday is today):

var nearestSunday = date.AddDays(7 - date.DayOfWeek == DayOfWeek.Sunday ? 7 : date.DayOfWeek);
