Parametri

transaction: DbTransaction

Transazione.

eventData: TransactionEventData

Informazioni contestuali sulla connessione e sulla transazione.

result: InterceptionResult

Rappresenta il risultato corrente se esiste. Questo valore sarà IsSuppressed impostato su true se un intercettatore precedente 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.

Restituisce

Task<InterceptionResult>

ValueTask<InterceptionResult>

Se IsSuppressed è false, EF continuerà come normale. Se IsSuppressed è true, EF elimina l'operazione che sta per eseguire. Un'implementazione di questo metodo per qualsiasi intercettatore che non tenta di eliminare l'operazione consiste nel restituire il result valore passato.

Eccezioni

OperationCanceledException

Se CancellationToken viene annullato.
