- transaction
- DbTransaction
Transazione.
- eventData
- TransactionEventData
Informazioni contestuali sulla connessione e sulla transazione.
- result
- InterceptionResult
Rappresenta il risultato corrente, se presente.
Questo valore sarà IsSuppressed impostato su true se un precedente intercettore ha eliminato l'esecuzione chiamando Suppress().
Questo valore viene in genere usato come valore restituito per l'implementazione di questo metodo.
- cancellationToken
- CancellationToken
Oggetto CancellationToken da osservare durante l'attesa del completamento dell'attività.
Valori restituiti
Se IsSuppressed è false, Entity Framework continuerà come di consueto.
Se IsSuppressed è true, Entity Framework elimina l'operazione che sta per eseguire.
Un'implementazione di questo metodo per qualsiasi intercettore che non tenta di eliminare l'operazione consiste nel restituire il result valore passato.
Eccezioni
Se l'oggetto CancellationToken viene annullato.
