Parâmetros

command: DbCommand

O comando.

eventData: CommandEventData

Informações contextuais sobre o comando e a execução.

result: InterceptionResult<Int32>

Representa o resultado atual se houver um. Esse valor terá HasResult definido como true se algum interceptador anterior suprimisse a execução chamando SuppressWithResult(TResult). Esse valor normalmente é usado como o valor retornado para a implementação desse método.

cancellationToken: CancellationToken

Um CancellationToken a ser observado enquanto aguarda a conclusão da tarefa.

Retornos

Task<InterceptionResult<Int32>>

ValueTask<InterceptionResult<Int32>>

Se HasResult for false, o EF continuará normalmente. Se HasResult for true, o EF suprimirá a operação que estava prestes a executar e usar Result . Uma implementação desse método para qualquer interceptador que não está tentando alterar o resultado é retornar o result valor passado, muitas vezes usando FromResult<TResult>(TResult)

Exceções

OperationCanceledException

Se o padrão CancellationToken for cancelado.
