설명

컨테이너는 0개 이상의 구성 요소를 캡슐화하고 추적하는 개체입니다. 이 컨텍스트에서 포함은 시각적 포함이 아닌 논리적 포함을 나타냅니다. 시각적 개체가 아닌 시나리오를 포함하여 다양한 시나리오에서 구성 요소 및 컨테이너를 사용할 수 있습니다.

구현자 참고

컨테이너가 되려면 클래스는 구성 요소를 추가, 제거 및 검색하는 메서드를 지원하는 인터페이스를 구현 IContainer 해야 합니다.

속성

Name	Description
Components	의 모든 구성 요소를 IContainer가져옵니다.

메서드

Name	Description
Add(IComponent, String)	목록의 끝에 지정된 IComponent IContainer 값을 추가하고 구성 요소에 이름을 할당합니다.
Add(IComponent)	목록의 끝에 지정된 IComponent IContainer 값을 추가합니다.
Dispose()	관리되지 않는 리소스의 해제, 해제 또는 재설정과 관련된 애플리케이션 정의 작업을 수행합니다. (다음에서 상속됨 IDisposable)
Remove(IComponent)	에서 구성 요소를 IContainer제거합니다.
