Regular expression for email authentication.

Question

Possible duplicate:
What is the best regular expression for checking email addresses?

I am using a form that requests an email address. I used regex for it as

.*@.*\..*

But it does not work fine for my test email id, e.g.

dsrasdf @@@ [e-mail]

Any of them provides me with a regular expression for checking email in asp.net or I can use some other method for this.

Please give your suggestions.
