how i can send data using TcpListener?

May 9 2018 1:11 PM
I want to be able to send data by using TcpListener how can i achieve this form this socks5 proxy project that listen to many connections using TcpListener.
i want to be able send data using only TcpListener from this 2 codes samples i am able to listen to many connections but i am not able to send data any help?
the link to whole project https://github.com/ThrDev/Socks5
