설명
Component는 IComponent의 기본 구현이며 공용 언어 런타임에서 모든 구성 요소의 기본 클래스 역할을 합니다.
컨테이너에 구성 요소를 포함시킬 수 있습니다. 여기서 포함은 시각적인 것이 아니라 논리적인 의미를 갖습니다. 시각적인 경우와 그렇지 않은 경우를 포함하는 다양한 시나리오에서 구성 요소와 컨테이너를 사용할 수 있습니다.
System.Windows.Forms.Control는 IComponent의 기본 구현인 Component에서 상속을 받습니다.
구성 요소는 주로 컨테이너에서 제공하고 컨테이너 고유의 구성 요소별 정보가 저장되는 리포지토리인 ISite를 통해 컨테이너와 상호 작용합니다.
구현자 참고 사항 구성 요소가 되기 위해 클래스는 IComponent 인터페이스를 구현하고 매개 변수를 요구하지 않거나 IContainer 형식의 단일 매개 변수를 요구하는 기본 생성자를 제공해야 합니다. IComponent 구현에 대한 자세한 내용은 구성 요소를 사용한 프로그래밍을 참조하십시오.
