컬렉션에 추가 XmlAnyElementAttribute 합니다.

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 개체입니다 XmlAnyElementAttribute .

반품

Int32

새로 추가 XmlAnyElementAttribute된 인덱스입니다.

예제

다음 예제에서는 새로 XmlAnyElementAttribute 만들고 속성을 통해 액세스 하는 개체의 컬렉션에 XmlAnyElements 추가 합니다. 그런 다음 , XmlAttributes 를 만드는 XmlSerializer데 사용되는 에 추가XmlAttributeOverrides됩니다. 개체 XmlSerializer 를 직렬화하거나 역직렬화하는 데 사용됩니다. 속성을 사용하는 XmlAnyElementAttributes 효과를 보려면 메서드에서 메서드 Main 를 실행 SerializeObject 하여 UnknownElements.xml XML 문서를 만듭니다. 결과 문서를 편집하여 다른(알 수 없는) 요소를 포함합니다. 메서드에서 호출을 SerializeObjectMain 주석 처리하고 알 수 없는 XML 요소의 이름과 값을 출력하는 메서드 호출의 주석 DeserializeObject 처리를 제거합니다.
