Parametri

eventData
CommandCorrelatedEventData

Informazioni contestuali sul comando e sull'esecuzione.

result
InterceptionResult<DbCommand>

Rappresenta il risultato corrente se esiste. Questo valore sarà HasResult impostato su true se un intercettatore precedente ha eliminato l'esecuzione chiamando SuppressWithResult(TResult). Questo valore viene in genere usato come valore restituito per l'implementazione di questo metodo.

Restituisce

InterceptionResult<DbCommand>

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