PackageStore.GetPackage(Uri) 메서드

정의

네임스페이스:

System.IO.Packaging

어셈블리:

PresentationCore.dll

저장소에서 지정된 URI의 Package를 반환합니다.

public:
 static System::IO::Packaging::Package ^ GetPackage(Uri ^ uri);

public static System.IO.Packaging.Package GetPackage (Uri uri);

static member GetPackage : Uri -> System.IO.Packaging.Package

Public Shared Function GetPackage (uri As Uri) As Package

매개 변수

uri

Uri

반환할 패키지의 URI(Uniform Resource Identifier)입니다.

반환

Package

지정된 packageUri의 패키지입니다. 지정된 packageUri의 패키지가 저장소에 없으면 null을 반환합니다.

예외

ArgumentNullException

packageUri이(가) null인 경우

ArgumentException

packageUri가 잘못된 패키지 URI인 경우

설명

packageUri 는 메서드 호출에 지정된 URI와 AddPackage 일치합니다.

보안 참고 사항 이 메서드는 EnvironmentPermission 모든 사용자 지정 Package (비ZipPackage) 형식을 요구합니다.

추가 정보

• AddPackage(Uri, Package)
• RemovePackage(Uri)
