Parametri

connection: DbConnection

Connessione.

eventData: TransactionEndEventData

Informazioni contestuali sulla connessione e sulla transazione.

result: DbTransaction

Risultato della chiamata a BeginTransactionAsync(IsolationLevel, CancellationToken). 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<DbTransaction>

ValueTask<DbTransaction>

Oggetto Task che fornisce il risultato che verrà usato da EF. Un'implementazione di questo metodo per qualsiasi intercettatore che non tenta di modificare il risultato consiste nel restituire il result valore passato, spesso usando FromResult<TResult>(TResult)

Eccezioni

OperationCanceledException

Se CancellationToken viene annullato.

Commenti

Questo metodo viene ancora chiamato se un intercettatore ha eliminato la creazione in TransactionStarting(DbConnection, TransactionStartingEventData, InterceptionResult<DbTransaction>). In questo caso, result è il risultato restituito da TransactionStarting(DbConnection, TransactionStartingEventData, InterceptionResult<DbTransaction>).
