설명
Component 기본 구현 IComponent 및 공용 언어 런타임에서 모든 구성 요소에 대 한 기본 클래스로 사용 됩니다.
컨테이너의 구성 요소를 포함할 수 있습니다. 이 컨텍스트에서 포함 하지 visual 포함 논리적인을 가리킵니다. 구성 요소 및 다양 한 시각적와 그렇지 않은 경우에에서는 컨테이너를 사용할 수 있습니다.
System.Windows.Forms.Control 상속 Component, 기본 구현의 IComponent합니다.
구성 요소에서 제공 하 고 컨테이너를 통해 기본적으로 컨테이너의 상호 작용 ISite, 컨테이너별 각 구성 요소에 대 한 정보의 저장소는 합니다.
구현자 참고
클래스는 구성 요소가 되도록 구현 해야 합니다 IComponent 인터페이스 및 매개 변수 없이 또는 형식의 단일 매개 변수를 필요로 하는 기본 생성자를 제공 IContainer합니다.
속성
Site |
ISite와 연결된 IComponent를 가져오거나 설정합니다. |
메서드
Dispose() |
관리되지 않는 리소스의 확보, 해제 또는 다시 설정과 관련된 애플리케이션 정의 작업을 수행합니다. (다음에서 상속됨 IDisposable) |
이벤트
Disposed |
구성 요소의 Disposed 이벤트를 처리하는 메서드를 나타냅니다. |
