PowerPoint 프레젠테이션에 C#

Question

의 슬라이드 추가 C# 추가 기능을 사용하면 PowerPoint에 단추를 추가하려고하는데 단추를 클릭하면 현재 프레젠테이션에 새 슬라이드가 추가됩니다.

나는 실제로 내가하고 싶은 일과 비슷하지만 ... 다른 PowerPoint 파일을 열고 슬라이드를 추가하기위한 것입니다. this solution입니다. 하지만 현재 프레젠테이션에 슬라이드를 추가하고 싶습니다.

주어진 코드를 수정하려고했지만 성공하지 못했습니다.

나는 문제가 있다고 생각 코드로이 질문에 삽입 시작과 코드
