UmAlQuraCalendar.IsLeapDay(Int32, Int32, Int32, Int32) Metodo

Definizione

Determina se la data specificata è un giorno intercalare.

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

Parametri

year
Int32

Un anno.

month
Int32

Valore intero compreso tra 1 e 12 che rappresenta un mese.

day
Int32

Valore integer compreso tra 1 e 30 che rappresenta un giorno.

era
Int32

Un'era. Specificare UmAlQuraCalendar.Eras[UmAlQuraCalendar.CurrentEra] o UmAlQuraEra.

Restituisce

true se il giorno specificato è intercalare; in caso contrario, false. Il valore restituito è sempre false perché la classe UmAlQuraCalendar non supporta i giorni intercalari.

Eccezioni

year, month, day o era non è compreso nell'intervallo supportato dalla classe UmAlQuraCalendar.

Esempio

Nell'esempio seguente viene chiamato il IsLeapDay metodo per l'ultimo giorno del secondo mese (febbraio) per cinque anni in ognuna delle era.

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();

   }
}
