stream associate with socket; will one end block another

[Ryan Liu]

Hi,

As I remember theare are In and Out stream associate with a socket.
TcpClient seems there in only one NetworkStream to do both read and write.

Then will it be a conflicit if both side try to send data?

And when one end is sending data, if another end is not calling Recevive or
BeginReceive, will the sender be blocked? Or recevier side network hardware
will read anyway, just our high-end application has not take the data yet?

BTW, if one side use sychronous/asychronous way to receive and send, the
anthoer side does not have to be same, right?

Thanks a lot!
Ryan

TCP is a implicit stream. .Net can suface that stream with the
NetworkStream Stream class, however you don't have to use it and can use raw
read/write methods on the socket.

Not really. But it could be a problem if your application protocol does not
expect that.

No. Both sides can send or receive at same time. If one side does not take
data fast enouph, the sender could eventually block because of no more
buffer space on receive end.

Until buffer space is full.

Each side can do either or both. That is a local design choice.
