Beispiele

Im folgenden Codebeispiel wird IsLeapYear in jeder der Zeiträume fünf Jahre lang aufgerufen.The following code example calls IsLeapYear for five years in each of the eras.

using namespace System;
using namespace System::Globalization;
int main()
{
   
   // Creates and initializes a GregorianCalendar.
   GregorianCalendar^ myCal = gcnew GregorianCalendar;
   
   // Displays the header.
   Console::Write( "YEAR\t" );
   for ( int y = 2001; y <= 2005; y++ )
      Console::Write( "\t {0}", y );
   Console::WriteLine();
   
   // Checks five years in the current era.
   Console::Write( "CurrentEra:" );
   for ( int y = 2001; y <= 2005; y++ )
      Console::Write( "\t {0}", myCal->IsLeapYear( y, GregorianCalendar::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 = 2001; y <= 2005; y++ )
         Console::Write( "\t {0}", myCal->IsLeapYear( y, myCal->Eras[ i ] ) );
      Console::WriteLine();

   }
}

Hinweise

Ein Schaltjahr im gregorianischen Kalender wird als Jahr definiert, das durch vier gleichmäßig teilbar ist, es sei denn, es ist durch 100 teilbar.A leap year in the Gregorian calendar is defined as a year that is evenly divisible by four, except if it is divisible by 100. Jahre, die durch 400 teilbar sind, sind jedoch Schaltjahre.However, years that are divisible by 400 are leap years. Beispielsweise war das Jahr 1900 kein Schaltjahr, aber das Jahr 2000 war.For example, the year 1900 was not a leap year, but the year 2000 was. Ein gemeinsames Jahr hat 365 Tage und ein Schaltjahr 366 Tage.A common year has 365 days and a leap year has 366 days.
