StorageFolder.DeleteAsync 메서드

정의

네임스페이스:

Windows.Storage

오버로드

DeleteAsync()	현재 폴더를 삭제합니다.
DeleteAsync(StorageDeleteOption)	현재 폴더를 삭제합니다. 이 메서드는 폴더를 영구적으로 삭제할지 여부도 지정합니다.

DeleteAsync()

현재 폴더를 삭제합니다.

 virtual IAsyncAction ^ DeleteAsync() = DeleteAsync;

/// [Windows.Foundation.Metadata.Overload("DeleteAsyncOverloadDefaultOptions")]
/// [Windows.Foundation.Metadata.RemoteAsync]

UnauthorizedAccessException

지정된 폴더를 삭제할 수 있는 권한이 없습니다.

예제

다음 예제에서는 DeleteAsync(StorageDeleteOption) 오버로드된 메서드를 호출하여 현재 폴더를 삭제하는 방법을 보여 줍니다. 이 예제에서는 파일을 영구적으로 삭제하는 옵션 의 값을 명시적으로 지정합니다.
