Chiamato subito prima che EF intenda chiamare RollbackAsync(CancellationToken).

Parametri

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.

Restituisce

Task<InterceptionResult>

ValueTask<InterceptionResult>

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

Implementazioni

TransactionRollingBackAsync(DbTransaction, TransactionEventData, InterceptionResult, CancellationToken)

Eccezioni

OperationCanceledException

Se CancellationToken viene annullato.
