For parsing HTML, you might want to look into the HTML Agility Pack. As for grabbing the HTML from a website, you can use WebClient.

@Aladdin Gallas if you have a specific question about using Html Agility Pack, ask it separately on SO. – NickAldwin Jun 27 '11 at 18:33
Thank you so much NickAldwin. I have to test it before and if I have issues I'll told you. – Aladdin Gallas Jun 27 '11 at 21:45

This guy wrote an article on using HtmlAgilityPack for web crawling from C#, and this is a framework for web crawling, though the project seems to be dead, you can look at them and see if they fit your needs.
