Whats the best way to format a message to a server, at moment I'm serilising an object using the binaryformatter and then sending it to the server.

At the server end its listening in an async fashion and then when the buffer size recieved is not 100% it assumes that the transfer has complete.

This is working and the moment, and I can deserialise the object at the other end, I'm just concerned that if I start sending async this method will fail has message's could be blurred.

I know that I need to mark the message somehow as to say that's the end of message one, this other bit belongs to message 2, but I'm unsure of the correct way to do this.

Could anyone point me in the right direction and maybe give me some examples?

Thanks
