Send and receive text between Arduino Mega 2560 and C# via ENC28J60

Question

I'm working on an Arduino project that sends and receives text to/from a C# application via ENC28J60 in a LAN network. Whenever C# sends a request to Arduino (In text), Arduino responds to it by sending also a text. What is the best way to do this? I'm newbie in network programming (Or whatever it's called). Thanls in advance :)

You can use TCP or UDP protocols.

You can use free UDP, TCP port listener sofwares for Windows, Linux etc.. for testing your setup.
