 override bool IsLeapDay(int year, int month, int day, int era);
public override bool IsLeapDay (int year, int month, int day, int era);
override this.IsLeapDay : int * int * int * int -> bool
Public Overrides Function IsLeapDay (year As Integer, month As Integer, day As Integer, era As Integer) As Boolean

參數

year
Int32

表示年份的整數。

month
Int32

從 1 到 13 的整數，表示月份。

day
Int32

從 1 到 30 的整數，表示日期。

era
Int32

表示紀元的整數。 請指定 HebrewEra 或 HebrewCalendar.Eras[Calendar.CurrentEra]。

傳回

Boolean

如果指定的日期為閏日，則為 true，否則為 false。

例外狀況

ArgumentOutOfRangeException

year、month、day 或 era 在這個曆法所支援的範圍之外。

範例

下列程式代碼範例會在每個紀元中呼叫 IsLeapDay 第二個月的最後一天 (2 月) 5 年。

   for ( int y = 5761; y <= 5765; y++ )
      Console::Write( "\t {0}", y );
   Console::WriteLine();
   
   // Checks five years in the current era.
   Console::Write( "CurrentEra:" );
   for ( int y = 5761; y <= 5765; y++ )

      Console::Write( "\t {0}", myCal->IsLeapDay( y, 2, iLastDay, HebrewCalendar::CurrentEra ) );

   }

備註

這個類別的 HebrewCalendar 實作只會辨識公曆 (1583 到 2239 年的希伯來文年份 5343 到 5999 年) 。

在每個 19 年週期中，以 19 平均除出的年份結束，第 3、6th、8th、11th、14th、17 和 19 年都是閏年。 一般年份可以有 353 到 355 天，視假日位置而定。 閏年可以有 383 到 385 天。

閏日是只在閏年發生的一天。 在希伯來歷中，Adar Alef 的最後一天和 Adar Beit 中的所有天數都會被視為閏日。
