추가 정보

적용 대상

GetDaysInMonth(Int32, Int32, Int32)

파생 클래스에 재정의될 때 지정된 월, 연도 및 연대의 일 수를 반환합니다.

매개 변수

year
Int32

연도를 나타내는 정수입니다.

month
Int32

월을 나타내는 양의 정수입니다.

era
Int32

연대를 나타내는 정수입니다.

반환

지정된 연대의 지정된 연도에 있는 지정된 월의 날짜 수입니다.

예외

year가 달력에서 지원하는 범위 밖에 있는 경우

또는

구현자 참고

파생 클래스는 매개 변수로 era 전달될 때 를 지원 CurrentEra 해야 합니다. 지원하는 CurrentEra 한 가지 방법은 달력의 현재 시대에 대한 값인 에 Eras[0]저장된 값으로 바꾸는 것입니다.
