I have a few questions about a file transfer client/server app I'm writing. I can set up the socket connection between them, and get a network stream where I can send text messages back and forth using asynchronous Send and Receive (BeginSend and BeginReceive) and using callbacks, now here's my question...

I've never done file transfer before, and I noticed that .NET has a FileStream object that I'd like to use. But I need to know if I should do asynchronous or syncrhonous writing to the file.

My head just gets confused trying to imagine the flow of the program because I'd be doing a BeginRead from the socket connection that fills up the buffer, once that is full the callback would need to write that buffer full of data to a file. Should I just do a synchronous FileStream.Write to a file then go back to getting another buffer full of file from the network stream? Or should I use a FileStream.BeginWrite to write the data to the file and implement a callback that would fetch another buffer full from the network stream. I'm just curious what the performance benefits are.

Thanks in advance,
