Unity-Arduino wifi Communication

Hi! Im looking for some simple example code that allows sending and recieving a string between my Arduino-Mega and Unity on my PC via my home Wifi. Im very unexperienced when it comes to non-serial communication and would appreciate any information on how to choose the port, which IP to use and if there must be a server-client communication or if it can just be two way direct. Thank you in advance for your help.,Dear Forum, Im looking for a simple example code which allows for sending and recieving a string between unity3d and arduino through my home wifi.
