SoapHeaderAttribute Class
This attribute is applied to an XML Web service method or an XML Web service client to specify a SOAP header that the XML Web service method or XML Web service client can process. This class cannot be inherited.
Assembly: System.Web.Services (in System.Web.Services.dll)
The basic steps to receiving and processing a SOAP header are:
Create a class deriving from SoapHeader representing the data passed in the SOAP header.
Add a member to the XML Web service class or XML Web service client proxy class of the type created in step 1.
Apply a SoapHeaderAttribute to the XML Web service method or the corresponding method in the proxy class, specifying the member created in step 2 in the MemberName property.
Within the XML Web service method or XML Web service client code, access the MemberName property to process the data sent in the SOAP header.
For more details, see the MemberName property.
The following MyWebService XML Web service defines one SoapHeader of type MyHeader. The Hello XML Web service method requires the client to invoke the XML Web service method with this SoapHeader. The Hello XML Web service also catches any SOAP headers other than MyHeader.
