Esempi

Nell'esempio seguente vengono enumerati i fusi orari trovati nel computer locale e vengono visualizzate le informazioni sulla fase di transizione per tutte le transizioni a data fissa.The following example enumerates the time zones found on the local computer and displays transition time information for all fixed-date transitions. Le informazioni sull'ora includono il giorno in cui si verifica il cambiamento di ora.The time information includes the day on which the time change occurs.

Commenti

La Day proprietà restituisce un valore valido solo se la IsFixedDateRule proprietà è true.The Day property returns a valid value only if the IsFixedDateRule property is true.

Il Day valore della proprietà corrisponde al valore day del parametro del CreateFixedDateRule metodo.The Day property value corresponds to the value of the day parameter of the CreateFixedDateRule method. Se il valore è maggiore del numero di giorni del mese della transizione, la transizione si verifica l'ultimo giorno del mese.If its value is greater than the number of days in the month of the transition, the transition occurs on the last day of the month.

La Day proprietà indica il giorno del mese in cui viene applicata una regola a data fissa, ad esempio il 15 aprile.The Day property indicates the day of the month on which a fixed-date rule is applied (for example, April 15). Al contrario, la DayOfWeek proprietà indica il giorno della settimana in cui viene applicata una regola a data mobile (ad esempio, la seconda domenica di novembre).In contrast, the DayOfWeek property indicates the day of the week on which a floating-date rule is applied (for example, the second Sunday of November).
