Custom pipeline functoid/komponent
Lägg DLL i C:\Program Files (x86)\Microsoft BizTalk Server\Pipeline Components (eller GAC:a)
Högerklicka på Biztalk Pipeline Components toolbox menyn i Visual Studio för att lägga till den

BodyPart stream to string
Stream originalStream = pInMsg.BodyPart.GetOriginalDataStream();
originalStream.Position = 0;
using (StreamReader reader = new StreamReader(originalStream, Encoding.UTF8))
{
    xmlString = reader.ReadToEnd();
}

String back to stream
return new MemoryStream(Encoding.UTF8.GetBytes(newString ?? ""));

Skriv över context värde / promote:a context värde
pInMsg.Context.Write("Username", "", reader["CurrentId"]);
pInMsg.Context.Promote("Username", "", reader["CurrentId"]);

Klona message Context
msg.Context = PipelineUtil.CloneMessageContext(sourceContext);
