user3313: I have a project in Microsoft Visual Studio C# and I have to pass JSON data to my Arduino via Ehternet Shield.  
This is how it works:

Is it possible? How to do it?

user3930: Yes.
If you're using an Ethernet Shield, you should be able to run a webserver on the Arduino and simple do an HTTP request from your C# webservice to the Arduino.
Check this tutorial on how to write a webserver for arduino using the ethernet shield: http://arduino.cc/en/Tutorial/WebServer
Doing an HTTP request of any kind from C# should be easy enough and is not in the scope of this site.
