Public Overrides Function GetDaysInMonth (year As Integer, month As Integer, era As Integer) As Integer

參數

year
Int32

一年。

month
Int32

從 1 到 12 的整數,表示月份。

era
Int32

一紀元。 指定 UmAlQuraCalendar.Eras[UmAlQuraCalendar.CurrentEra]UmAlQuraEra

備註

這個方法會針對一般年份和閏年,傳回指定月份中的不同天數。 例如,這個方法會傳回 Zulhijjah 的 29 或 30 (month = 12) ,視是否 year 為閏年而定。
