Commenti

Per ottenere l'oggetto Configuration per una risorsa, il codice deve disporre dei privilegi di lettura per tutti i file di configurazione da cui eredita le impostazioni. Per aggiornare un file di configurazione, il codice deve inoltre disporre dei privilegi di scrittura sia per il file di configurazione che per la directory in cui esiste.

Questo metodo viene usato per accedere a un file di configurazione usando la rappresentazione.

Per ottenere l'oggetto Configuration per una risorsa remota, il codice deve disporre di privilegi amministrativi nel computer remoto.

Potrebbe essere necessario eseguire ASP.NET iis Registration Tool (Aspnet_regiis.exe) con l'opzione -config+ per abilitare l'accesso ai file di configurazione nel computer remoto.
