설명

일반적으로 메서드를 CheckBoxList.GetItemStyle 사용하여 개체에서 항목 CheckBoxList 의 스타일을 검색해야 합니다.

IRepeatInfoUser.GetItemStyle 메서드는 명시적 인터페이스 멤버 구현 합니다. CheckBoxList 인스턴스가 IRepeatInfoUser 인터페이스로 캐스팅된 경우에만 사용할 수 있습니다.

상속자 참고

개체에서 항목의 스타일을 검색하기 위한 사용자 지정 구현을 CheckBoxList 정의하려면 멤버를 재정의합니다 GetItemStyle(ListItemType, Int32) . 명시적 인터페이스 구현은 메서드를 GetItemStyle(ListItemType, Int32) 호출하여 항목의 스타일을 검색합니다.
