Hi... I am very new in programming. Trying to learn from google search. I am trying to make a simple web browser through vs 2013 which will have random user-agent option.

My idea is.... there will be a text file where I will keep all different user-agent strings.
The browser will take UA from there randomly with each request. I got this idea from a firefox addon (Random Agent Spoofer).

I made a simple browser...but can't find any tutorial out there about this. can anyone please help me?
