Manually Check Email Address Validity

I am validating an online form, and naturally one of the fields to validate is an email address.

Does anybody have a function available that checks the validay of a string to be a valid email address?

Unfortunately I need a bit more flexibility than is provided by the RegularExpressionValidator object - unless I can somehow call it without hard binding it (if that makes sense).

I can see that the following is used by this control as the Email format:

\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*

Any ideas?

What is the additional flexibility that you need? Are you trying to limit domains or something like that?

No, I just want to be able to check from within a code block. Like if strXYZ is aValidEmail then do suchandsuch .... i don't actually want to validate a text box...

You would just use a System.Text.RegularExpressions.Regex object with the same regular expression.

cool... thanks. i had never seen that before and was just what i was after....

ps.... takes another aussie to solve my prob. cheers mate!

My ex-wife actually went to the same school as Micheal Hutchence. He's practically my brother. :D I don't know Kevin Bacon though.

Why you shouldn't use RegEx to validate email addresses :)

And here is the RFC 822 standard for email addresses, although it doesn't provide an implementation of validating them.

It's actually quite a complex operation, as this thread will attest.

Anyway, HTH :)


Edit: I don't know what fool decided to put acronyms in the word filter, but in the last link, replace the asterisk'ed letters with W, T, and F, in that order ;)
