Question

I need to write simple TCP listener that will be able to listen TCP ( receive packages ) on one thread and in case i need to send some package i will be able to do it on some other thread

How can i do it ?

Answer 1

You could use the TcpListener class. It has asynchronous versions of the methods such as BeginAcceptTcpClient which will in turn give you an instance of a TcpClient on which you could call GetStream to reach the underlying stream and from there on continue using the asynchronous versions on this stream to BeginRead and BeginWrite.
