JapaneseCalendar.IsLeapYear(Int32, Int32) 方法
定义
重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
确定指定纪元中的指定年份是否为闰年。
public:
override bool IsLeapYear(int year, int era);public override bool IsLeapYear (int year, int era);override this.IsLeapYear : int * int -> boolPublic Overrides Function IsLeapYear (year As Integer, era As Integer) As Boolean参数
- year
- Int32
一个整数，用于表示年份。
- era
- Int32
一个整数，用于表示纪元。
返回
如果指定的年份是闰年，则为 true；否则为 false。
例外
示例
以下示例在每个纪元中调用 IsLeapYear 五年。 示例输出中的当前纪元是 Reiwa 纪元。

注解
日本历中的闰年对应于公历中的同一闰年。 公历中的闰年定义为公历的公历年，除可被 100 整除外，公历年可被 4 均匀地整除。 然而，被400整除的公历年是闰年。 普通年份有 365 天，闰年有 366 天。
