SoapClientMessage.OneWay Property
Assembly: System.Web.Services (in system.web.services.dll)
A SoapDocumentMethodAttribute or SoapRpcMethodAttribute applied to an XML Web service method or XML Web service client can specify whether the XML Web service method is one way by setting the OneWay property of the attribute.
The OneWay property can be accessed during any SoapMessageStage.
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 particular fragment outputs to that log file a phrase stating the XML Web service method is one-way, when the OneWay property is true.
