UmAlQuraCalendar.IsLeapDay(Int32, Int32, Int32, Int32) 方法
定義
重要
部分資訊涉及發行前產品,在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊,不做任何明確或隱含的瑕疵擔保。
判斷指定的日期是否為閏日。
public:
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
一年。
- month
- Int32
從 1 到 12 的整數,表示月份。
- day
- Int32
1 到 30 的整數,表示日期。
- era
- Int32
一紀元。 指定 UmAlQuraCalendar.Eras[UmAlQuraCalendar.CurrentEra]
或 UmAlQuraEra。
傳回
如果指定的日期為閏日,則為 true
,否則為 false
。 傳回值永遠都會是 false
,因為 UmAlQuraCalendar 類別不支援閏月。
例外狀況
year
、month
、day
或 era
不在 UmAlQuraCalendar 類別支援的範圍內。
範例
下列範例 IsLeapDay 會針對第二個月的最後一天呼叫 方法, (2 月) 每一個紀元的五年。

for ( int y = 1421; y <= 1425; y++ )
Console::Write( "\t {0}", y );
Console::WriteLine();
// Checks five years in the current era.
