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。

示例
以下示例在每个时代都调用 IsLeapYear 5 年。 示例输出中的当前时代是 Reiwa 时代。

// Checks five years in the current era.
Console::Write( "CurrentEra:" );
for ( int y = 1; y <= 5; y++ )

注解
日本日历中的 Leap 年对应于公历中的同一跃年。 公历中的一个跃年被定义为公历的公历年，该年被四个公历均匀地除以 100。 然而，被400分位的公历年是飞跃年。 普通年份有 365 天，跃年有 366 天。
