EF가 를 호출한 직후 호출 ExecuteScalarAsync()합니다.

매개 변수

command
DbCommand

명령입니다.

eventData
CommandExecutedEventData

명령 및 실행에 대한 컨텍스트 정보입니다.

result
Object

에 대한 호출의 결과입니다 ExecuteScalarAsync(). 이 값은 일반적으로이 메서드의 구현에 대 한 반환 값으로 사용 합니다.

cancellationToken
CancellationToken

CancellationToken 작업이 완료 될 때까지 기다리는 동안 관찰할 입니다.

반환

Task<Object>
ValueTask<Object>

Task EF에서 사용할 결과를 제공하는 입니다. 결과를 변경하려고 하지 않는 인터셉터에 대해 이 메서드를 구현하는 것은 전달된 값을 반환 result 하는 것입니다( 종종 사용). FromResult<TResult>(TResult)

예외

OperationCanceledException

CancellationToken이 취소된 경우.

설명

이 메서드는 인터셉터에서 에서 명령 실행을 억제한 경우에도 여전히 호출됩니다 ScalarExecutingAsync(DbCommand, CommandEventData, InterceptionResult<Object>, CancellationToken). 이 경우 는 result 에서 반환 ScalarExecutingAsync(DbCommand, CommandEventData, InterceptionResult<Object>, CancellationToken)된 결과입니다.
