FileIOPermission.GetPathList 메서드

  • 아티클

지정된 FileIOPermissionAccess가 있는 모든 파일과 디렉터리를 가져옵니다.

네임스페이스: System.Security.Permissions
어셈블리: mscorlib(mscorlib.dll)

구문

‘선언
Public Function GetPathList ( _
    access As FileIOPermissionAccess _
) As String()
‘사용 방법
Dim instance As FileIOPermission
Dim access As FileIOPermissionAccess
Dim returnValue As String()

returnValue = instance.GetPathList(access)

public string[] GetPathList (
    FileIOPermissionAccess access
)

public:
array<String^>^ GetPathList (
    FileIOPermissionAccess access
)

public String[] GetPathList (
    FileIOPermissionAccess access
)

public function GetPathList (
    access : FileIOPermissionAccess
) : String[]

매개 변수

반환 값

access 매개 변수에서 지정한 액세스 권한이 부여되는 파일과 디렉터리의 경로를 포함하는 배열입니다.

예외

예외 형식 조건

ArgumentException

access가 유효한 FileIOPermissionAccess 값이 아닌 경우

- 또는 -

access는 두 가지 형식 이상의 파일 액세스를 나타내는 AllAccess이나 어떤 형식의 파일 액세스도 나타내지 않는 NoAccess 중 하나인 경우

설명

이 메서드를 사용하여 현재 사용 권한의 상태를 가져옵니다. Read 및 Write 액세스 권한의 상태를 모두 가져오려면 이 메서드를 두 번 호출해야 합니다.

참고

access 매개 변수는 FileIOPermissionAccess의 값으로 제한됩니다. 이 값은 한 가지 형식의 파일 액세스를 나타냅니다. 그 값은 Read, Write, Append 및 PathDiscovery입니다. NoAccess 및 AllAccess는 한 가지 형식의 파일 액세스를 나타내지 않으므로 access의 값으로 사용할 수 없습니다.
