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 -> bool
Public 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
下面的代码示例在每个纪元中调用 IsLeapYear
方法五年。
using namespace System;
using namespace System::Globalization;
int main()
{
// Creates and initializes a HijriCalendar.
HijriCalendar^ myCal = gcnew HijriCalendar;
// Displays the header.
Console::Write( "YEAR\t" );
for ( int y = 1421; y <= 1425; y++ )
Console::Write( "\t {0}", y );
Console::WriteLine();
// Checks five years in the current era.
Console::Write( "CurrentEra:" );
for ( int y = 1421; y <= 1425; y++ )
Console::Write( "\t {0}", myCal->IsLeapYear( y, HijriCalendar::CurrentEra ) );
Console::WriteLine();
// Checks five years in each of the eras.
for ( int i = 0; i < myCal->Eras->Length; i++ )
{
Console::Write( "Era {0}:\t", myCal->Eras[ i ] );
for ( int y = 1421; y <= 1425; y++ )
Console::Write( "\t {0}", myCal->IsLeapYear( y, myCal->Eras[ i ] ) );
Console::WriteLine();
}
