C#에서 파일 동기화 프로그램을 만드는 동안 copy의 LocalFileItem 클래스에서 이 인 System.IO.File.Copy(destination.Path, Path, true) 메서드를 사용하는 클래스를 만들려고했습니다.
이 코드를 대상으로 실행 한 후 Path = "C:\\Test2" 및 this.Path = "C:\\Test\\F1.txt" 나는 예외 내가 C에서이 작업을 수행하는 데 필요한 파일 권한이없는 것을 말하는 얻을 : \ 테스트하지만 C : \ 테스트 자신에 (현재 사용자)가 소유하고 있습니다.
아무도 무슨 일이 일어나고 있는지 또는이 문제를 해결하는 방법을 알고 있습니까?C#의 파일 권한 정보
여기에 원본 코드가 있습니다.
