이 확장 메서드는 중첩 된 어셈블리를 포함하여 모든 참조 된 어셈블리를 재귀 적으로 가져옵니다.
를 사용할 ReflectionOnlyLoad
때 별도의 AppDomain에 어셈블리를로드하므로 JIT 프로세스를 방해하지 않는다는 장점이 있습니다.
또한 MyGetMissingAssembliesRecursive
. 이를 사용하여 참조되었지만 어떤 이유로 현재 디렉터리에 존재하지 않는 누락 된 어셈블리를 검색 할 수 있습니다. 이것은 MEF를 사용할 때 매우 유용합니다 . 반환 목록은 누락 된 어셈블리와 소유자 (부모)를 모두 제공합니다.
