public:
override bool IsLeapDay(int year, int month, int day, int era);
public override bool IsLeapDay (int year, int month, int day, int era);
override this.IsLeapDay : int * int * int * int -> bool
Public Overrides Function IsLeapDay (year As Integer, month As Integer, day As Integer, era As Integer) As Boolean
Parâmetros
- year
- Int32
Um ano.A year.
- month
- Int32
Um inteiro de 1 a 12 que representa um mês.An integer from 1 through 12 that represents a month.
- day
- Int32
Um inteiro de 1 a 30 que representa um dia.An integer from 1 through 30 that represents a day.
- era
- Int32
Uma era.An era. Especifique UmAlQuraCalendar.Eras[UmAlQuraCalendar.CurrentEra] ou UmAlQuraEra.Specify UmAlQuraCalendar.Eras[UmAlQuraCalendar.CurrentEra] or UmAlQuraEra.
Retornos
true se o dia especificado for um dia bissexto; caso contrário, false.true if the specified day is a leap day; otherwise, false. O valor retornado é sempre false, pois a classe UmAlQuraCalendar não dá suporte a dias bissextos.The return value is always false because the UmAlQuraCalendar class does not support leap days.
Exceções
year, month, day ou era está fora do intervalo com suporte da classe UmAlQuraCalendar.year, month, day, or era is outside the range supported by the UmAlQuraCalendar class.
Exemplos
O exemplo a seguir chama o IsLeapDay método para o último dia do segundo mês (fevereiro) por cinco anos em cada um dos apagamentos.The following example calls the IsLeapDay method for the last day of the second month (February) for five years in each of the eras.
using namespace System;
using namespace System::Globalization;
int main()
{
// Creates and initializes a HijriCalendar.
HijriCalendar^ myCal = gcnew HijriCalendar;
// Creates a holder for the last day of the second month (February).
int iLastDay;
// 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++ )
{
iLastDay = myCal->GetDaysInMonth( y, 2, HijriCalendar::CurrentEra );
Console::Write( "\t {0}", myCal->IsLeapDay( y, 2, iLastDay, 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++ )
{
iLastDay = myCal->GetDaysInMonth( y, 2, myCal->Eras[ i ] );
Console::Write( "\t {0}", myCal->IsLeapDay( y, 2, iLastDay, myCal->Eras[ i ] ) );
}
Console::WriteLine();
}
}
