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。
using namespace System;
using namespace System::Globalization;
int main()
{
// Creates and initializes a TaiwanCalendar.
TaiwanCalendar^ myCal = gcnew TaiwanCalendar;
// Displays the header.
Console::Write( "YEAR\t" );
for ( int y = 90; y <= 94; y++ )
Console::Write( "\t {0}", y );
Console::WriteLine();
// Checks five years in the current era.
Console::Write( "CurrentEra:" );
for ( int y = 90; y <= 94; y++ )
Console::Write( "\t {0}", myCal->IsLeapYear( y, TaiwanCalendar::CurrentEra ) );
Console::WriteLine();
// Checks five years in each of the eras.

for ( int y = 90; y <= 94; y++ )

注解
台湾历法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，可均匀除以 4 的公历年，除非它被 100 除。 然而，可除以 400 的公历年是闰年。 普通年份有 365 天，闰年有 366 天。
