설명

ResourceProviderFactory 전역 및 로컬 리소스 공급자를 반환 하는 개체에 대 한 기본 클래스로 사용 되는 추상 클래스입니다. 클래스에서 파생 되어야 합니다 ResourceProviderFactory 해당 기능을 구현 합니다.

생성자

ResourceProviderFactory()

파생 클래스에서 구현되면 파생 클래스의 새 인스턴스를 초기화합니다.

메서드

CreateGlobalResourceProvider(String)	파생 클래스에서 재정의되면 전역 리소스 공급자를 만듭니다.
CreateLocalResourceProvider(String)	파생 클래스에서 재정의되면 로컬 리소스 공급자를 만듭니다.
Equals(Object)	지정된 개체가 현재 개체와 같은지 확인합니다. (다음에서 상속됨 Object)
GetHashCode()	기본 해시 함수로 작동합니다. (다음에서 상속됨 Object)
GetType()	현재 인스턴스의 Type을 가져옵니다. (다음에서 상속됨 Object)
MemberwiseClone()	현재 Object의 단순 복사본을 만듭니다. (다음에서 상속됨 Object)
ToString()	현재 개체를 나타내는 문자열을 반환합니다. (다음에서 상속됨 Object)
