MessageQueues that pass an object with another object in it.

[UJ]

I have an object I'm using to pass around data using a messagequeue. It has
a small header in it and then a reference to a variable of type object. I do
this so that I can have a generic message that everybody uses. My message
router looks at the object, sees who it needs to go to and forwards it
along. The recipient knows how to decode it.

Problem is, when I make the object a class of my own creation, I get an
error. It says "There was an error generating the XML document.".

Anybody have any ideas? I guess I could use the objects directly and stick
in it who it is going to.

TIA - Jeff.

You need to serialize the objects and assign them to the Message Body, and
then deserialize ("unwrap") your outer class for routing, then at the
receiving end, the inner payload class. Try using the
BinaryMessageFormatter, its more efficient than Xml which generates a larger
payload.

What I do is use the BinaryFormatter to serialize the inner class to byte[]
and assign this to the Payload property of the outer "Routing" message.
