Question

I am trying to understand this document .

But I do not understand how to implement it in my previous code, which I did in accordance with this link .

Can anyone provide me some sample code to continue.

The C # library that you use in your "previous code" is a wrapper around the Google Contacts API protocol, which is the document you are trying to understand. More precisely, this is a wrapper around the Google Data API that Google Contacts provides.

A protocol is actually REST calls that return ATOM and / or JSON channels to you. You can implement this in C # using WebRequest and WebResponse, and analyze the result using something like XMLReader, but why do you do it if you already have a library that does this for you?
