Définition

En cas de substitution dans une classe dérivée, détermine si un mois est un mois d’une année bissextile.When overridden in a derived class, determines whether a month is a leap month.

Surcharges

IsLeapMonth(Int32, Int32, Int32)

En cas de substitution dans une classe dérivée, détermine si le mois de l’année spécifiée dans l’ère spécifiée est un mois bissextile.When overridden in a derived class, determines whether the specified month in the specified year in the specified era is a leap month.

IsLeapMonth(Int32, Int32)

Détermine si le mois spécifié de l’année spécifiée dans l’ère en cours est un mois bissextile.Determines whether the specified month in the specified year in the current era is a leap month.

IsLeapMonth(Int32, Int32, Int32)

En cas de substitution dans une classe dérivée, détermine si le mois de l’année spécifiée dans l’ère spécifiée est un mois bissextile.When overridden in a derived class, determines whether the specified month in the specified year in the specified era is a leap month.

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

Paramètres

year
Int32

Entier qui représente l’année.An integer that represents the year.

month
Int32

Entier positif qui représente le mois.A positive integer that represents the month.

era
Int32

Entier qui représente l’ère.An integer that represents the era.

Retours

true si le mois spécifié est un mois bissextile ; sinon, false.true if the specified month is a leap month; otherwise, false.

Exceptions

year est en dehors de la plage prise en charge par le calendrier.year is outside the range supported by the calendar.

-ou--or- month est en dehors de la plage prise en charge par le calendrier.month is outside the range supported by the calendar.

-ou--or- era est en dehors de la plage prise en charge par le calendrier.era is outside the range supported by the calendar.

Remarques

Pour créer la différence entre l’année civile et l’heure réelle à laquelle la terre pivote autour du soleil ou l’heure à laquelle la lune pivote autour de la terre, une année bissextile a un nombre de jours différent d’une année civile standard.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. Chaque implémentation de Calendar définit des années bissextiles différemment.Each Calendar implementation defines leap years differently.

Un mois d’une année bissextile est un mois complet qui se produit uniquement dans une année bissextile.A leap month is an entire month that occurs only in a leap year. Par exemple, dans le calendrier hébreu, Adar Beit est le seul mois d’une année bissextile.For example, in the Hebrew calendar, Adar Beit is the only leap month.

Notes pour les responsables de l’implémentation

La classe dérivée doit prendre en charge CurrentEra lorsqu’elle est passée comme paramètre era.The derived class must support CurrentEra when it is passed as the era parameter. L’une des façons de prendre en charge CurrentEra consiste à la remplacer par la valeur stockée dans ères [0], qui est la valeur de l’ère actuelle du calendrier.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.
