Need to search a webpage for a word OR search links in it

[C# Programming]

Hey,
I'm programming a little app, and I need a code in order to search a web page for a word, and clicking on it or copying it etc.
Or if that is hard, maybe extract all the links into a file and then searching the file..

Any of these will do it.

Obviously C#..
