설명
는 ConfigurationElementCollection 구성 파일 내의 요소 컬렉션을 나타냅니다.
참고
구성 파일 내의 요소는 기본 XML 요소 또는 섹션을 참조합니다. 단순 요소는 관련 특성이 있는 XML 태그(있는 경우)입니다. 단순 요소는 섹션을 구성합니다. 복합 섹션에는 하나 이상의 간단한 요소, 요소 컬렉션 및 기타 섹션이 포함될 수 있습니다.
사용 하 여는 ConfigurationElementCollection 개체의 ConfigurationElement 컬렉션을 사용 하 여 작업 합니다. 사용자 지정 ConfigurationElement 요소의 컬렉션을 에 추가하려면 이 클래스를 ConfigurationSection구현합니다.
구현자 참고
프로그래밍 방식 또는 선언적(특성이 지정된) 코딩 모델을 사용하여 사용자 지정 구성 요소를 만들 수 있습니다.
프로그래밍 방식 모델을 사용하려면 각 요소 특성에 대해 해당 값을 가져오고 설정하는 속성을 만들고 기본 ConfigurationElement 기본 클래스의 내부 속성 모음에 추가해야 합니다.
특성 모델이라고도 하는 선언적 모델을 사용하면 속성을 사용하고 특성으로 구성하여 요소 특성을 정의할 수 있습니다. 이러한 특성은 ASP.NET 구성 시스템에 속성 형식 및 해당 기본값에 대해 지시합니다. ASP.NET 리플렉션을 사용하여 이 정보를 가져온 다음 요소 속성 개체를 만들고 필요한 초기화를 수행할 수 있습니다.
