Parâmetros

command: DbCommand

O comando.

eventData: CommandExecutedEventData

Informações contextuais sobre o comando e a execução.

result: Object

O resultado da chamada para ExecuteScalarAsync(). 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<Object>

ValueTask<Object>

Um Task que fornece o resultado que o EF usará. Uma implementação desse método para qualquer interceptador que não esteja tentando alterar o resultado é retornar o result valor passado, muitas vezes usando FromResult<TResult>(TResult)

Exceções

OperationCanceledException

Se o padrão CancellationToken for cancelado.

Comentários

Esse método ainda será chamado se um interceptador suprimiu a execução de um comando em ScalarExecutingAsync(DbCommand, CommandEventData, InterceptionResult<Object>, CancellationToken). Nesse caso, result é o resultado retornado por ScalarExecutingAsync(DbCommand, CommandEventData, InterceptionResult<Object>, CancellationToken).
