Açıklamalar

Bu yöntem, parametresini yılın son gününe ayarlayarak time yıl içindeki hafta sayısını belirlemek için kullanılabilir.

CultureInfo.DateTimeFormatve firstDayOfWeek parametreleri için kullanılabilecek kültüre rule özgü değerler içerir.

FirstDayOfWeek özelliği, özelliğinde CultureInfo.DateTimeFormatCultureInfo.DateTimeFormatCalendar belirtilen takvimi kullanarak belirli bir kültür için haftanın ilk gününü temsil eden varsayılan DayOfWeek değeri içerir.

CalendarWeekRule özelliği, özelliğinde CultureInfo.DateTimeFormatCalendar belirtilen takvimi kullanarak belirli bir kültür için takvim haftasını CultureInfo.DateTimeFormattanımlayan varsayılan CalendarWeekRule değeri içerir.

Örneğin, GregorianCalendariçinde GetWeekOfYear , 1 Ocak için 1 döndürür.
