IsLeapDay(Int32, Int32, Int32)

현재 연대의 지정 된 날짜가 윤 일인지 여부를 결정 합니다.Determines whether the specified date in the current era is a leap day.

IsLeapDay(Int32, Int32, Int32, Int32)

파생된 클래스에서 재정의 되 면 지정 된 연대의 지정 된 날짜가 윤 일인지 여부를 결정 합니다.When overridden in a derived class, determines whether the specified date in the specified era is a leap day.

IsLeapDay(Int32, Int32, Int32)

Public Overridable Function IsLeapDay (year As Integer, month As Integer, day As Integer) As Boolean

Parameters

year
Int32

Exceptions

year가 달력에서 지원하는 범위 밖에 있는 경우year is outside the range supported by the calendar.

-또는--or- month가 달력에서 지원하는 범위 밖에 있는 경우month is outside the range supported by the calendar.

-또는--or- day가 달력에서 지원하는 범위 밖에 있는 경우day is outside the range supported by the calendar.

Remarks

하기 위해 달력 연도 및 지구 태양 중심으로 회전 하는 실제 시간 또는 달 지구 중심으로 회전 하는 실제 시간 간의 차이 윤년에 표준 달력 연도의 다른 기간 (일)To make up for the difference between the calendar year and the actual time that the earth rotates around the sun or the actual time that the moon rotates around the earth, a leap year has a different number of days from a standard calendar year. Calendar 구현은 윤년을 다르게 정의 합니다.Each Calendar implementation defines leap years differently.

윤 일은 윤년 에서만에서 발생 하는 일입니다.A leap day is a day that occurs only in a leap year. 예를 들어 일반 달력에서 2 월 29 일이만 윤 일 합니다.For example, in the Gregorian calendar, the 29th day of February is the only leap day.

IsLeapDay(Int32, Int32, Int32, Int32)

파생된 클래스에서 재정의 되 면 지정 된 연대의 지정 된 날짜가 윤 일인지 여부를 결정 합니다.When overridden in a derived class, determines whether the specified date in the specified era is a leap day.

public:
 abstract bool IsLeapDay(int year, int month, int day, int era);
public abstract bool IsLeapDay (int year, int month, int day, int era);
abstract member IsLeapDay : int * int * int * int -> bool
Public MustOverride Function IsLeapDay (year As Integer, month As Integer, day As Integer, era As Integer) As Boolean

Parameters

year
Int32

연도 나타내는 정수입니다.An integer that represents the year.

month
Int32

월을 나타내는 양의 정수입니다.A positive integer that represents the month.

day
Int32

일을 나타내는 양의 정수입니다.A positive integer that represents the day.

era
Int32

연대를 나타내는 정수입니다.An integer that represents the era.

Returns

Boolean

지정된 날짜가 윤일이면 true이고, 그렇지 않으면 false입니다.true if the specified day is a leap day; otherwise, false.

Exceptions

year가 달력에서 지원하는 범위 밖에 있는 경우year is outside the range supported by the calendar.

-또는--or- month가 달력에서 지원하는 범위 밖에 있는 경우month is outside the range supported by the calendar.

-또는--or- day가 달력에서 지원하는 범위 밖에 있는 경우day is outside the range supported by the calendar.

-또는--or- era가 달력에서 지원하는 범위 밖에 있는 경우era is outside the range supported by the calendar.

Notes to Implementers

파생 클래스는 era 매개 변수로 전달 될 때 CurrentEra을 지원 해야 합니다.The derived class must support CurrentEra when it is passed as the era parameter. CurrentEra를 지 원하는 한 가지 방법은 calendar [0]에 저장 된 값으로 대체 하는 것입니다 .이 값은 달력의 현재 연대의 값입니다.One way to support CurrentEra is by replacing it with the value stored in Eras[0], which is the value for the current era of the calendar.
