예제

다음 예제에서는 에 를 UnreferencedObjectEventHandler 추가합니다 XmlSerializer. 이벤트는 메서드에 Serializer_UnreferencedObject 의해 처리됩니다. 예제를 실행하려면 다음 XML을 잘라내어 UnrefObj.xml 파일에 붙여넣습니다.

설명

클래스에 UnreferencedObjectEventArgs 대한 자세한 내용은 의 이벤트를 참조 UnreferencedObject 하세요 XmlSerializer.

이벤트는 UnreferencedObject 메서드를 호출 Deserialize 할 때만 발생합니다.

이벤트 처리에 대한 자세한 내용은 이벤트 개요를 참조하세요.

생성자

UnreferencedObjectEventArgs(Object, String)

UnreferencedObjectEventArgs 클래스의 새 인스턴스를 초기화합니다.

속성

UnreferencedId	개체의 ID를 가져옵니다.
UnreferencedObject	역직렬화되었지만 참조되지 않은 개체를 가져옵니다.

메서드

Equals(Object)	지정된 개체가 현재 개체와 같은지 확인합니다. (다음에서 상속됨 Object)
GetHashCode()	기본 해시 함수로 작동합니다. (다음에서 상속됨 Object)
GetType()	현재 인스턴스의 Type을 가져옵니다. (다음에서 상속됨 Object)
MemberwiseClone()	현재 Object의 단순 복사본을 만듭니다. (다음에서 상속됨 Object)
ToString()	현재 개체를 나타내는 문자열을 반환합니다. (다음에서 상속됨 Object)
