L’exemple suivant définit une ChangeCalendar méthode qui modifie le calendrier actuel d’une culture en un calendrier spécifié, sauf s’il s’agit déjà du calendrier actuel ou s’il n’est pas pris en charge par la culture.The following example defines a ChangeCalendar method that changes a culture's current calendar to a specified calendar unless it is already the current calendar or if it is not supported by the culture. Le code qui appelle la méthode instancie un CultureInfo objet qui représente la culture arabe (Égypte) et tente d’abord de remplacer son calendrier par le calendrier japonais.The code that calls the method instantiates a CultureInfo object that represents the Arabic (Egypt) culture and first attempts to change its calendar to the Japanese calendar. Étant donné que le calendrier japonais n’est pas pris en charge, la méthode ne modifie pas le calendrier de la culture.Because the Japanese calendar is not supported, the method makes not change the culture's calendar. Toutefois, étant donné que le calendrier Um al-Qura est membre de CultureInfo.OptionalCalendars la collection, la méthode parvient à en faire le calendrier actuel pour la culture ar-eg.However, because the Umm al-Qura calendar is a member of the CultureInfo.OptionalCalendars collection, the method does succeed in making it the current calendar for the ar-EG culture.
