C# - Sending and Receiving a TCP/IP message to an IP Address and Port

Question

I have the following code to send a TCP/IP message to a specific IP Address and Port:

public bool sendTCPMessage(string ip_address, string port, string trans         


        

Answer 1

You'd need a TcpListener object to act as the server. The TcpListener object would listen for incoming connections on the specified port. You can use the .AcceptTcpClient method to establish a new connection. (If you wanted multiple clients you'd have to look into multithreading)

Also as a side note using Port 1 would be bad practice, low port numbers are usually reserved for system stuff or standard protocols such as telnet, ftp, http etc.
