방법: 격리된 스토리지의 파일 및 디렉터리 삭제

  • 아티클

격리된 스토리지 파일 내에서 디렉터리 및 파일을 삭제할 수 있습니다. 저장소 내에서 파일 및 디렉터리 이름은 운영 체제에 종속적이며 가상 파일 시스템의 루트와 관련하여 지정됩니다. Windows 운영 체제에서는 대/소문자를 구분하지 않습니다.

System.IO.IsolatedStorage.IsolatedStorageFile 클래스는 DeleteDirectory 및 DeleteFile이라는 두 가지 메서드를 제공하여 디렉터리와 파일을 삭제합니다. 존재하지 않는 파일 또는 디렉터리를 삭제하려고 하면 IsolatedStorageException 예외가 throw됩니다. 이름에 와일드 카드 문자를 포함하는 경우 DeleteDirectory는 IsolatedStorageException 예외를 throw하고, DeleteFile은 ArgumentException 예외를 throw합니다.

디렉터리에 파일 또는 하위 디렉터리가 포함된 경우에는 DeleteDirectory 메서드가 실패합니다. GetFileNames 및 GetDirectoryNames 메서드를 사용하여 기존 파일 및 디렉터리를 검색할 수 있습니다. 저장소의 가상 파일 시스템을 검색하는 방법에 대한 자세한 내용은 방법: 격리된 스토리지의 기존 파일 및 디렉터리 찾기를 참조하세요.

예시

다음 코드 예제에서는 여러 디렉터리 및 파일을 생성한 후 삭제합니다.
