설명

일시적 인리스트먼트를 사용하여 트랜잭션에 대한 결과 정보를 가져오는 대신 이 이벤트에 등록할 수 있습니다. 대리자에게 TransactionCompletedEventHandler 전달된 매개 변수는 Transaction instance. 그런 다음 특정 instance 속성을 쿼리 TransactionInformation 하여 또는 값이 있는 트랜잭션 CommittedAborted 의 TransactionInformationStatus 상태 포함하는 의 instance 가져올 수 있습니다.

주의 이 이벤트에 등록하면 연결된 트랜잭션의 성능에 부정적인 영향을 줍니다.
