매개 변수

connection
DbConnection

연결입니다.

eventData
ConnectionEventData

연결에 대한 컨텍스트 정보입니다.

result
InterceptionResult

있는 경우 현재 결과를 나타냅니다. 이전의 일부 인터셉터에서 를 호출Suppress()하여 true 실행을 억제한 경우 이 값은 로 설정됩니다IsSuppressed. 이 값은 일반적으로이 메서드의 구현에 대 한 반환 값으로 사용 합니다.

cancellationToken
CancellationToken

CancellationToken 작업이 완료 될 때까지 기다리는 동안 관찰할 입니다.

반환

Task<InterceptionResult>
ValueTask<InterceptionResult>

가 이false면 IsSuppressed EF는 정상적으로 계속됩니다. 이 true이면 IsSuppressed EF는 수행하려는 작업을 표시하지 않습니다. 작업을 억제하려고 하지 않는 모든 인터셉터에 대해 이 메서드의 구현은 전달된 값을 반환 result 하는 것입니다.

예외

OperationCanceledException

CancellationToken이 취소된 경우.
