Before sending the data send a datatype maybe as a enumerated type, integer or string. Maybe create a struct that has a datatype field? Just some ideas... HTH Luke

You should search CodeProject. There is lots of examples and topics regarding socket programming. How do you know the data types? You're the one sending and receiving them, so you dictate what those structures are. If you didn't create these structures for either the client or the server, then you need to consult the documentation for the socket client or server that you're trying to talk to. As far as sending files, you just send them using a buffer (a Byte[] array) as is. For strings and XML, just send the character data using the proper encoding (see System.Text.Encoding for more information). You get the Byte[] array for the characters based on an agreed encoding between client and server. You can either assume a single encoding between the two, or send data (much like HTTP, SMTP/MIME, etc.) using an encoding that one dictates.
