설명

이 메서드는 RegisterName를 호출 하는 편리한 방법입니다.This method is a convenience method for calling RegisterName. 구현에서는 INameScope를 구현 하는 요소를 검색 하 여 발견 되는 해당 NameScope 구현을 찾을 때까지 연속 부모 요소를 확인 합니다.The implementation will check successive parent elements until it finds the applicable NameScope implementation, which is found by finding an element that implements INameScope. 이름 범위에 대 한 자세한 내용은 WPF XAML 이름 범위를 참조 하세요.For more information about namescopes, see WPF XAML Namescopes.

호출 RegisterName 코드에서 만들 때 애플리케이션에 대 한 애니메이션 스토리 보드를 올바르게 연결 하기 위해 필요 합니다.Calling RegisterName is necessary in order to correctly hook up animation storyboards for applications when created in code. 이는 키 storyboard 속성 TargetName중 하나가 대상 요소에 대 한 참조를 가져올 수 없는 대신 런타임 이름 조회를 사용 하기 때문입니다.This is because one of the key storyboard properties, TargetName, uses a run-time name lookup instead of being able to take a reference to a target element. 이는 해당 요소를 코드의 참조로 액세스할 수 있는 경우에도 마찬가지입니다.This is true even if that element is accessible by reference from the code. 스토리 보드 대상의 이름을 등록 해야 하는 이유에 대 한 자세한 내용은 Storyboard 개요를 참조 하세요.For more information on why you need to register names for storyboard targets, see Storyboards Overview.
