SoapUnknownHeader.Element 속성

정의

네임스페이스:

System.Web.Services.Protocols

어셈블리:

System.Web.Services.dll

SOAP 요청 또는 응답에 대한 XML 헤더 요소를 가져오거나 설정합니다.

public:
 property System::Xml::XmlElement ^ Element { System::Xml::XmlElement ^ get(); void set(System::Xml::XmlElement ^ value); };

public System.Xml.XmlElement Element { get; set; }

member this.Element : System.Xml.XmlElement with get, set

Public Property Element As XmlElement

속성 값

XmlElement

SOAP 헤더의 원시 XML을 나타내는 XmlElement입니다.

예제

다음 MyWebService 이외의 비롯 하 여 모든 SOAP 헤더를 수신 하는 XML 웹 서비스는 MyHeader SOAP 헤더를 인식 합니다. MyWebMethod XML 웹 서비스 메서드에 문자열로 전달 된 마지막 알 수 없는 SOAP 헤더의 XML 특성을 클라이언트에 반환 합니다.

설명

경우는 XML 웹 서비스 메서드를 알지 못합니다에 대 한 XML 웹 서비스는 작성 당시 SOAP 헤더를 처리 하려는 것을 처리할 수는 XmlElement SOAP 헤더의 원시 XML을 나타내는 클래스입니다.
