What is the best regular expression for validating email addresses?

I'm using a form which ask for email address. I used regular expression for it as

.*@.*\..*

But it is not working fine for some of my test email id like

dsrasdf@@@[email protected]

Any one provide me regular expression for the email validation in asp.net or can i use any other method for it.

Please give your suggestions.

Answer 1

Best to rely on the framework for this kind of stuff.

try {
    address = new MailAddress(address).Address;
} catch(FormatException) {
    //address is invalid
}

Answer 2

I am using the following regular expression for my email validations (case insensitive):

^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$

I do not know about asp, but i think that you can use it like this.
