다음보기 모델에 바인딩 된 ASP.Net MVC 폼이 있습니다. 이 양식을 통해 한 제출자는 그의 전화 번호와 약속 유형과 함께 새로운 직원 기록을 삽입 할 수 있습니다. LINQ to SQL을 사용하는 컨트롤러 [HttpPost] 작업은 EContactInfo 및 AppointmentType 테이블을 제외한 People (직원) 테이블 과 연결된 테이블에 단일 레코드 삽입을 수행 할 수 있습니다. _StaffSerivce.Add()는 단순히 데이터 저장소에서 해당 엔티티의 InsertOnSubmit()을 실행합니다. 모든 새 레코드가 추가 된 후 데이터 저장소의 SubmitChanges()가 실행되는 _Service.Save()가 호출됩니다. 그 때 "이미 사용중인 키가있는 엔티티를 추가 할 수 없습니다."이라는 오류가 나타납니다. 첫 번째 전화 번호 또는 약속 유형을 삽입 할 때 오류가 발생하면 첫 번째 레코드가 각 테이블에 삽입 된 후 해당 테이블의 기본 키가 변경되지 않습니다. 일괄 적으로 많은 레코드를 하나의 테이블에 삽입 할 수 있습니까? 감사.ASP.Net LINQ 일괄 처리 테이블에 레코드 삽입

오류는 Entity Framework에서 가져온 것이므로이 태그를 추가했습니다. _service.Save 메소드에 대한 코드를 추가하십시오. 오류가 스택에서 발생하는 곳입니다 (가정합니다). – kingdango
의견을 주셔서 감사합니다. EF가 아닌 SQL에 LINQ를 사용하고 있습니다. 원래 게시물에 save() 메소드를 추가했습니다. – user266909
사과드립니다. 나는 총을 뛰어 넘었습니다. :-) – kingdango
