How to determine the request & response packet size of a Web Service

[AesopTurtle]

Hi there, Is it possible to determine the request and response packet size of a Web Service? Say... I would like to create a progress bar on my application to determine how many percentage the web service has performed. My idea is first to determine the packet size of the xml document sent/received by the web service. Then update the progress bar every, say... 10 kb, as the web service performs. So anyone please tell me how to determine the packet size using C#. If there is a better approach, please do not hesitate to suggest me. Thank you very much. KiT
