using namespace System;
using namespace System::Globalization;
void PrintPattern( String^ myCulture )
{
   CultureInfo^ MyCI = gcnew CultureInfo( myCulture,false );
   DateTimeFormatInfo^ myDTFI = MyCI->DateTimeFormat;
   Console::WriteLine( " {0} {1}", myCulture, myDTFI->RFC1123Pattern );
}

int main()
{
   
   // Displays the values of the pattern properties.
   Console::WriteLine( " CULTURE    PROPERTY VALUE" );
   PrintPattern( "en-US" );
   PrintPattern( "ja-JP" );
   PrintPattern( "fr-FR" );
}

Commenti

La proprietà RFC1123Pattern definisce il formato specifico delle impostazioni cultura delle stringhe di data restituite dalle chiamate ai metodi DateTime.ToString e DateTimeOffset.ToString e alle stringhe di formato composite che forniscono le stringhe di formato standard "r" e "R".The RFC1123Pattern property defines the culture-specific format of date strings that are returned by calls to the DateTime.ToString and DateTimeOffset.ToString methods and by composite format strings that are supplied the "r" and "R" standard format strings.

Il modello RFC1123 riflette uno standard definito e la proprietà è di sola lettura.The RFC1123 pattern reflects a defined standard, and the property is read-only. Pertanto, è sempre lo stesso, indipendentemente dalle impostazioni cultura.Therefore, it is always the same, regardless of the culture. La stringa di formato personalizzata è "ddd, dd MMM yyyy HH':'mm':'ss 'GMT".The custom format string is "ddd, dd MMM yyyy HH':'mm':'ss 'GMT'".
