Esempio

L'esempio di codice seguente ottiene il valore minimo e il valore massimo del calendario.

using namespace System;
using namespace System::Globalization;

int main()
{
   // Create an instance of the calendar.
   HijriCalendar^ myCal = gcnew HijriCalendar;
   Console::WriteLine( myCal );
   
   // Create an instance of the GregorianCalendar.
   GregorianCalendar^ myGre = gcnew GregorianCalendar;
   
   // Display the MinSupportedDateTime and its equivalent in the GregorianCalendar.
   DateTime myMin = myCal->MinSupportedDateTime;
   Console::Write( "MinSupportedDateTime: {0:D2}/{1:D2}/{2:D4}", myCal->GetMonth( myMin ), myCal->GetDayOfMonth( myMin ), myCal->GetYear( myMin ) );
   Console::WriteLine( " (in Gregorian, {0:D2}/{1:D2}/{2:D4})", myGre->GetMonth( myMin ), myGre->GetDayOfMonth( myMin ), myGre->GetYear( myMin ) );
   
   // Display the MaxSupportedDateTime and its equivalent in the GregorianCalendar.
   DateTime myMax = myCal->MaxSupportedDateTime;
   Console::Write( "MaxSupportedDateTime: {0:D2}/{1:D2}/{2:D4}", myCal->GetMonth( myMax ), myCal->GetDayOfMonth( myMax ), myCal->GetYear( myMax ) );
   Console::WriteLine( " (in Gregorian, {0:D2}/{1:D2}/{2:D4})", myGre->GetMonth( myMax ), myGre->GetDayOfMonth( myMax ), myGre->GetYear( myMax ) );

Commenti

Microsoft Visual Basic rappresenta l'ora del giorno come ora specificata nella data minima supportata dal DateTime tipo, ovvero il 1° gennaio 0001 C.E. Tuttavia, il HijriCalendar tipo non supporta tale data minima. Di conseguenza, se si chiama un metodo per formattare l'ora del giorno usando il calendario corrente, ma non si specifica un identificatore di formato, la formattazione usa l'identificatore di formato del modello ISO 8601 ordinabile ("s") data/ora anziché l'identificatore di formato del modello di data/ora predefinito ("G"). Per altre informazioni, vedere Stringhe di formato data e ora standard.
