[C#] MDB(Access) 파일을 읽어 Excel에 넣고 Excel 실행 예제 [출처] MDB(Access) 파일을 읽어 Excel에 넣고 Excel 실행 예제

student.mdb 파일은 Student라는 테이블이 있으며 그 내용은 다음과 같습니다.

id        name        addr        tel
1        가길동        서울        11-2222
2        나기롱        울산        222-3333
3        다길동        부산        444-5555

이를 통해 만들어진 student.xls 파일은 다음과 같이 생겼습니다...
위의 mdb 파일과 내용이 같겠죠^^;;;

id        name        addr        tel
1        가길동        서울        11-2222
2        나기롱        울산        222-3333
3        다길동        부산        444-5555

소스 코드는 다음과 같습니다.
