EnvironmentPermission.SetPathList(EnvironmentPermissionAccess, String) 메서드

정의

네임스페이스:

System.Security.Permissions

어셈블리:

System.Security.Permissions.dll

어셈블리:

mscorlib.dll

지정된 환경 변수에 대한 지정된 액세스 권한을 사용 권한의 기존 상태로 설정합니다.

public:
 void SetPathList(System::Security::Permissions::EnvironmentPermissionAccess flag, System::String ^ pathList);

public void SetPathList (System.Security.Permissions.EnvironmentPermissionAccess flag, string pathList);

member this.SetPathList : System.Security.Permissions.EnvironmentPermissionAccess * string -> unit

Public Sub SetPathList (flag As EnvironmentPermissionAccess, pathList As String)

매개 변수

flag

EnvironmentPermissionAccess

EnvironmentPermissionAccess 값 중 하나입니다.

pathList

String

환경 변수 목록(세미콜론으로 구분)입니다.

예외

ArgumentNullException

pathList 매개 변수가 null인 경우

ArgumentException

flag 매개 변수가 EnvironmentPermissionAccess의 유효한 값이 아닙니다.
