Using SOAP Headers in Pipeline Components

To access the SOAP header context properties in pipeline components, you use a combination of the context property name and target namespace as discussed in Using SOAP Headers in Orchestrations.

The following code example sets the request SOAP header in a send pipeline component for a property name OrigDest:

public IBaseMessage Execute(IPipelineContext pc, IBaseMessage inmsg)  
{  
   try  
      {  
       string stringVar = "<?xml version=\"1.0\"?>  
          <OrigDest xmlns=\"http://SOAPHeaderSchemas.OrigDestSOAPHeader\">  
             <Origination>Home</Origination>  
             <Destination>Work</Destination>  
          </OrigDest>";  
inmsg.Context.Write("OrigDest","http://schemas.microsoft.com/BizTalk/2003/SOAPHeader", stringVar);  
      }  
   catch (Exception ex)  
      {  
   throw new Exception("Pipeline component exception - " + ex.Message);  
      }  
return inmsg;  
}

For more information about pipeline components, see Developing Custom Pipeline Components.

Note

When you consume (call) Web services from an orchestration, the SOAP adapter only supports pass-through style receive and send pipelines. You can use a custom pipeline, but it cannot contain components that modify the body parts of the message. These components include the XML Assembler, XML Disassembler, and XML Validator components.
