Body = email Header "\n" email Body; //send the message Smtp Client smtp = new Smtp Client(Server Address); smtp. So when I try to send an email using this code, I get the exception: "The specified string is not in the form required for an e-mail address." Is there any way to validate the comma delimited email addresses? There does not appear to be a good way to validate email addresses.

Now the problem is that, in case of multiple comma delimited addresses, one or two of them might be of the wrong email address format. You know it's just an example, and I know it's just an example, but many of them don't read before they copy and paste.

Send(mail); Now the "to Address" string that my function recieves might contain a single address, or it might have many, comma delimited addresses. You know how many people find these answers and just copy and paste code.

This is to verify that I actually own that email address before my account is activated.

Trying to match these restrictions is a complex task, often resulting in long regular expressions. NET Framework regular expression classes are part of the base class library and can be used with any language or tool that targets the common language runtime, including ASP. The following C# source code shows how to validate an email address with the help of regular expressions.

Here’s a fairly common code sample from Rails Applications with some sort of authentication system: If you’re experienced at Regex, this seems simple. Sections 3.2.4 and 3.4.1 of the RFC go into the requirements on how an email address needs to be formatted and, well, there’s not much you can’t do in your email address when quotes or backslashes are involved.

At this point, why keep parsing email addresses for their format?

The result of sending an email to a badly formatted email address would be the same: it’ll get bounced. If you really want to do checking of email addresses right on the signup page, include a confirmation field so they have to type it twice.

What I'm looking for is a regular expression that I can use in my C# code that is definitive.
