Definizione
Importante
Alcune informazioni sono relative alla release non definitiva del prodotto, che potrebbe subire modifiche significative prima della release definitiva. Microsoft non riconosce alcuna garanzia, espressa o implicita, in merito alle informazioni qui fornite.
Quando ne viene eseguito l'override in una classe derivata, ottiene la tabella codici del sistema operativo Windows che meglio corrisponde alla codifica corrente.

Tabella codici del sistema operativo Windows che meglio corrisponde all'oggetto Encoding corrente.
Esempio
Nell'esempio seguente viene determinata la tabella codici di Windows che corrisponde maggiormente a ogni codifica.
using namespace System;
using namespace System::Text;
int main()
{
// Print the header.
Console::Write( "CodePage identifier and name " );
Console::WriteLine( "WindowsCodePage" );
// For every encoding, get the Windows code page for it.
System::Collections::IEnumerator^ myEnum = Encoding::GetEncodings()->GetEnumerator();
while ( myEnum->MoveNext() )
{
EncodingInfo ^ ei = safe_cast<EncodingInfo ^>(myEnum->Current);
Encoding^ e = ei->GetEncoding();
Console::Write( "{0,-6} {1,-25} ", ei->CodePage, ei->Name );
Console::Write( "{0,-6} ", e->WindowsCodePage );
// Mark the ones that are different.
if ( ei->CodePage != e->WindowsCodePage )
Console::Write( "*" );
Console::WriteLine();
}
}

Questa proprietà viene fornita per la compatibilità con le API MLang (Windows Multilanguage), ad esempio, per determinare le famiglie di caratteri. Per la globalizzazione è invece consigliabile usare una delle codifiche Unicode. È inoltre consigliabile utilizzare WebName anziché WindowsCodePage per identificare la tabella codici.
