SoapExtension::ChainStream Method
When overridden in a derived class, allows a SOAP extension access to the memory buffer containing the SOAP request or response.
Assembly: System.Web.Services (in System.Web.Services.dll)
Parameters
- stream
- Type: System.IO::Stream
A memory buffer containing the SOAP request or response.
Return Value
Type: System.IO::StreamA Stream representing a new memory buffer that this SOAP extension can modify.
ChainStream ensures that SOAP extensions with the highest priority can modify the actual data closest to the SOAP message sent or returned over the wire.
SOAP extensions should save references of the Stream passed into ChainStream and the Stream returned from ChainStream. If the SOAP extension is configured to run with a XML Web service method, the Stream passed into ChainStream contains the serialized SOAP request at the BeforeDeserialize SoapMessageStage. Similarily, the Stream reference returned from ChainStream is written into when the serialization occurs and thus contains the serialized SOAP response in the AfterSerialize SoapMessageStage.
