Esempio

Il MyWebService servizio Web XML accetta ed elabora l'intestazione MyHeader SOAP inviata con qualsiasi chiamata al metodo del MyWebMethod servizio Web XML. Riceve inoltre MyWebMethod tutte le intestazioni SOAP diverse dall'intestazione MyHeader SOAP.

// Define a SOAP header by deriving from the SoapHeader base class.

public class MyHeader : SoapHeader {
    public string MyValue;
}

public class MyWebService {

    public MyHeader myHeader;
    // Receive all SOAP headers besides the MyHeader SOAP header.
    public SoapUnknownHeader[] unknownHeaders;
 
    [WebMethod]
    [SoapHeader("myHeader", Direction=SoapHeaderDirection.InOut)]

    //Receive any SOAP headers other than MyHeader.
    [SoapHeader("unknownHeaders")]

    public string MyWebMethod() {

    string unknownHeaderAttributes = String.Empty;

        // Set myHeader.MyValue to some value.
         
       foreach (SoapUnknownHeader header in unknownHeaders) {
           // Perform some processing on the header.
           foreach (XmlAttribute attribute in header.Element.Attributes) {
              unknownHeaderAttributes = unknownHeaderAttributes + attribute.Name + ":" + attribute.Value + ";";            
           }
           // For those headers that cannot be 
           // processed, set the DidUnderstand property to false.

Commenti

Un client SOAP potrebbe richiamare un servizio Web XML con dati aggiuntivi oltre i parametri obbligatori sotto forma di intestazione SOAP. Un servizio Web XML creato utilizzando ASP.NET o un client del servizio Web XML può visualizzare tutte le intestazioni SOAP relative al momento in cui il servizio Web XML è stato scritto applicando un SoapHeaderAttribute oggetto con una MemberName proprietà di una matrice di SoapHeader, SoapHeaderSoapUnknownHeader o una matrice di SoapUnknownHeader al metodo del servizio Web XML. La specifica Type di SoapUnknownHeaderconsente al servizio Web XML di visualizzare il contenuto dell'intestazione SOAP sotto forma di .XmlElement
