PackUriHelper.ResolvePartUri(Uri, Uri) 메서드

정의

지정된 소스 파트 URI와 대상 파트에 대한 상대 경로를 가진 URI에 대한 파트 URI를 반환합니다.

public:
 static Uri ^ ResolvePartUri(Uri ^ sourcePartUri, Uri ^ targetUri);
public static Uri ResolvePartUri (Uri sourcePartUri, Uri targetUri);
static member ResolvePartUri : Uri * Uri -> Uri
Public Shared Function ResolvePartUri (sourcePartUri As Uri, targetUri As Uri) As Uri

매개 변수

sourcePartUri
Uri

소스 파트의 URI 또는 Package 루트를 나타내는 "/"입니다.

targetUri
Uri

대상 파트에 대한 상대 URI입니다.

반환

Uri

지정된 SourcePartUritargetUri 매개 변수 사이에서 확인되는 대상 파트의 URI입니다.

예외

sourcePartUri 또는 targetUrinull인 경우

sourcePartUri가 올바른 파트 URI가 아닌 경우

또는

targetUri가 올바른 상대 URI가 아닌 경우
