判斷指定紀元中指定的年份是否為閏年。

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

參數

year
Int32

表示年份的整數。

era
Int32

表示紀元的整數。

傳回

Boolean

如果指定的年份是閏年，則為 true，否則為 false。

例外狀況

ArgumentOutOfRangeException

year 不在曆法支援的範圍內。

-或-

era 不在曆法支援的範圍內。

範例

下列範例會在每個紀元中呼叫 IsLeapYear 五年。 範例輸出中的目前紀元是 Reiwa 紀元。

   Console::WriteLine();

備註

日曆中的閏年對應至公曆中的相同閏年。 公曆中的閏年會定義為公曆的公曆年，此年會平均除以四，除非以100除。 不過，由 400 除的公曆年是閏年。 一般年份有 365 天，而閏年有 366 天。
