Are you using the ESP with an Arduino or stand-alone? – Majenko♦ Aug 25 '17 at 10:37

There are many options. What exactly do you want to do? – Johnny Mopp Aug 25 '17 at 13:22

Either use TCP or UDP to communicate. With TCP one end will be the server and will open a socket (your choice) and the other end will connect to it (much like communicating with a web server). With UDP both ends will open a socket and send discrete packets backwards and forwards.
How you would do either of those in C# is outside the scope of this website.
The ESP8266 has AT commands that perform the task for you - chiefly AT+CIPSTART.
The simplest to understand is probably TCP communication where you can just follow any of the myriad of website based examples. However instead of communicating with a website using HTTP you will be communicating with your own server software written in C# using your own custom designed protocol.
A simpler option may be to use a real web server as a "man in the middle" to which both the ESP8266 and your C# program communicate. That website could become a database back-end for your program.
Of course, what you decide to do depends entirely on how complex your program is and what data it is you want to transfer.

I just want to send a simple string from esp8266 to my C# application. I do not want to go for a web server. Can we do this like we do with serial port and arduino. Can you send me some useful links – Ans Bilal Aug 25 '17 at 12:46

you can use a serial port, but a web server would be much simpler to deploy as it would not require client drivers. – dandavis Aug 27 '17 at 22:48
