SSIS Team Blog에서 다음 코드를 가져와 AcquireConnection() 메서드에서 사용할 수 있도록 OLEDB 연결 유형을 형 변환합니다. 이제는 Dts.Connections 파트가 작동하지 않는 이유가 확실하지 않습니다. 나는 그것을 작동하게 만들기 위해 추가해야 할 라이브러리를 모른다. 나는 Dts.RuntimeWrap을 포함하여 가장 중요한 것들을 추가했다. 질문에 대한 자세한 정보가 필요하면 알려주십시오.OLEDB 연결 유형을 참조하는 누락 된 라이브러리

어떤 오류가 발생합니까? 내가 지적한 코드를 테스트 한 결과 올바른 것으로 보입니다. – Chopin
Oledb 연결을 사용하여 비슷한 문제가 발생했습니다. 포기하고 방금 ADO.net 연결을 사용하여 이러한 문제가 발생하지 않습니다. 비록 당신의 사건에 가능성이 있는지는 모르겠지만 ... – cfrag
@Chopin. 오류 메시지가 나타납니다. "오류 \t 1 형식 또는 네임 스페이스 이름 'Connections'이 (가) 네임 스페이스 'AOC.SqlServer.Dts'에 없습니다 (어셈블리 참조가 누락 되었습니까?)"모든 참조 및 내용을 확인했지만 내가 뭘 놓치고 있는지 모르겠다. – rvphx
