Is there a way to know how much space a serialized object transmitted in

Is there a way to know how much space a serialized object transmitted in a WCF netTCP binding takes?
I am getting a

The socket connection was aborted.
This could be caused by an error
processing your message or a receive

host, or an underlying network
resource issue. Local socket timeout

error and I think that it may be due to the size of the datatable I am transmitting back.
Is there a way in Windows debugger to determine how much space (bytes) the data to be transmitted back will take?

    Well, the easiest (and most accurate) option would probably be to set it to the max in the config (so it doesn’t explode) and use WireShark to measure it during transmission; in theory you could use WCF message logging/tracing, but I’ve had hit-and-miss results when using that with large messages.

    Alternatively, you could try using NetDataContractSerializer to write the data to a MemoryStream, and look at the .Length of the stream?

    Note that if you are using classes (rather than DataTable), you might find another serializer helps; it isn’t 100% scientific, but I recently compared NetDataContractSerialzier and protobuf-net.
