XmlAnyElementAttribute을 컬렉션에 추가합니다.

public:
 int Add(System::Xml::Serialization::XmlAnyElementAttribute ^ attribute);

public int Add (System.Xml.Serialization.XmlAnyElementAttribute attribute);

public int Add (System.Xml.Serialization.XmlAnyElementAttribute? attribute);

member this.Add : System.Xml.Serialization.XmlAnyElementAttribute -> int

Public Function Add (attribute As XmlAnyElementAttribute) As Integer

매개 변수

attribute

XmlAnyElementAttribute

추가할 XmlAnyElementAttribute입니다.

반환

Int32

새로 추가한 XmlAnyElementAttribute의 인덱스입니다.

예제

다음 예제에서는 새로 XmlAnyElementAttribute 만들고 속성을 통해 액세스 하는 개체의 컬렉션에 XmlAnyElements 추가 합니다. 그런 다음 , XmlAttributes 를 만드는 데 사용되는 에 추가 XmlAttributeOverrides됩니다 XmlSerializer. XmlSerializer 직렬화하거나 개체를 역직렬화하는 데 사용 됩니다. 속성을 사용하는 XmlAnyElementAttributes 효과를 보려면 메서드에서 메서드 Main 를 실행 SerializeObject 하여 UnknownElements.xml XML 문서를 만듭니다. (알 수 없는) 다른 요소를 포함 하려면 결과 문서를 편집 합니다. 주석으로 처리를 SerializeObject 에서 호출 합니다 Main 메서드를에 대 한 호출을 주석 처리 제거를 DeserializeObject 이름과 알 수 없는 XML 요소의 값을 출력 하는 메서드를 합니다.
