Email-address validation

[Mika M]

Simple question: Does Framework (1.1) contain any routine to check entered
email-address is valid ?

It's quite easy to make own code for that purpose, but why to do if
Framework (1.1) contain this kind of routine.

Thanks in advance!

Re: Email-address validation

Hi,
You can use regular expressions for that. Check out the
System.Text.Reg ularExpressions namespace in the FCL. You can get regular
expressions for various pattern and format validations from many web sites.
One such site is http://www.regexlib.com/

don't be a smart-ass herf! is it quite easy to validate email addresses no
matter what rfc you design your code after...and, 822 is the simplest. you
could have at least chosen a harder one to support your smugness.

why are you an "mvp"?

Re: Email-address validation

good attempt but not fully rfc compliant...doe sn't handle:

joe blow <jblow@abc.co m>
"super dave osborne"@abc.co m
snoozing.susan@ abc.com

etc., etc., etc.

Well, I would not consider writing the regular expression for RFC compliant
email address validation an "easy" job:

Why aren't you an MVP?

Why are you dumping on Herfried?
