Answer 1

I would say that it depends on what the client expects, but JSON usually works well to concisely represent structured data.

i will convert any of above three to byte array and send it into the
stream.

If the client is a web browser, it isn’t going to know what to do with a byte array (unless it is sent as a binary type, which doesn’t seem appropriate here). Send the data as a string.

The JavaScriptSerializer or DataContractJsonSerializer are meant for serializing data to JSON.
