I Want to Know How To search files that are saved on the Driive ??

For starters, check this Daniweb thread to search for files.

[Codefiva]

I will suggest you to go for winform instead of console application.

I agree with Codefiva, but if you insist on using a console app, perhaps have a look at this codesnippet. Also avoid us names as n for your methods use a meaningfull name.
