Examples

The following code fragment is part of a SOAP extension that logs the SOAP messages sent and received by an XML Web service client. This specific fragment processes the SoapClientMessage passed into the SoapExtension.ProcessMessage method of the SOAP extension by writing properties of the SoapClientMessage to the log file.

// Process the SOAP message received and write to a log file.
void ProcessMessage( SoapMessage^ message )

   switch ( message->Stage )

         break;
      case SoapMessageStage::BeforeDeserialize:
         WriteInput( dynamic_cast<SoapClientMessage^>(message) );
         break;
      case SoapMessageStage::AfterDeserialize:
         break;
      default:
         throw gcnew Exception( "invalid stage" );
   }
}

// Write the contents of the outgoing SOAP message to the log file.

      FileAccess::Write );

      "================================== Request at {0}", DateTime::Now );

Properties

Action	Gets the `SOAPAction` HTTP request header field for the SOAP request or SOAP response.
Client	Gets an instance of the client proxy class, which derives from SoapHttpClientProtocol.
ContentEncoding	Gets or sets the contents of the `Content-Encoding` HTTP header. (Inherited from SoapMessage)
ContentType	Gets or sets the HTTP `Content-Type` of the SOAP request or SOAP response. (Inherited from SoapMessage)
Exception	Gets the SoapException from the call to the XML Web service method. (Inherited from SoapMessage)
Headers	A collection of the SOAP headers applied to the current SOAP request or SOAP response. (Inherited from SoapMessage)
MethodInfo	Gets a representation of the method prototype of the XML Web service method for which the SOAP request is intended.
OneWay	Gets a value indicating whether the client waits for the server to finish processing an XML Web service method.
SoapVersion	Gets the version of the SOAP protocol used to communicate with the XML Web service.
SoapVersion	Gets the version of the SOAP protocol used to communicate with the XML Web service. (Inherited from SoapMessage)
Stage	Gets the SoapMessageStage of the SoapMessage. (Inherited from SoapMessage)
Stream	Gets the data representing the SOAP request or SOAP response in the form of a Stream. (Inherited from SoapMessage)
Url	Gets the URL of the XML Web service.

Methods

EnsureInStage()	When overridden in a derived class, asserts that the current SoapMessageStage is a stage where in parameters are available. (Inherited from SoapMessage)
EnsureOutStage()	When overridden in a derived class, asserts that the current SoapMessageStage stage is a stage where out parameters are available. (Inherited from SoapMessage)
EnsureStage(SoapMessageStage)	Ensures that the SoapMessageStage of the call to the XML Web service method is the stage or stages passed in. If the current processing stage is not one of the stages passed in, an exception is thrown. (Inherited from SoapMessage)
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetInParameterValue(Int32)	Gets the parameter passed into the XML Web service method at the specified index. (Inherited from SoapMessage)
GetOutParameterValue(Int32)	Gets the out parameter passed into the XML Web service method at the specified index. (Inherited from SoapMessage)
GetReturnValue()	Gets the return value of an XML Web service method. (Inherited from SoapMessage)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
