UnreferencedObjectEventArgs 클래스의 새 인스턴스를 초기화합니다.

public:
 UnreferencedObjectEventArgs(System::Object ^ o, System::String ^ id);

public UnreferencedObjectEventArgs (object? o, string? id);

public UnreferencedObjectEventArgs (object o, string id);

new System.Xml.Serialization.UnreferencedObjectEventArgs : obj * string -> System.Xml.Serialization.UnreferencedObjectEventArgs

Public Sub New (o As Object, id As String)

매개 변수

o: Object

참조되지 않은 개체입니다.

id: String

참조되지 않은 개체를 식별하는 데 사용되는 고유 문자열입니다.

예제

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