I think the MailAddress constructor is more than sufficient for his current purposes a quick check before sending for the first time. You should also note that emails are usually delimited with semicolons, not commas. Kobi, it used to be Now only commas are accepted. FYI, using MailAddress to validate an email address isn't foolproof. It seems to allow some bad addresses that shouldn't get through like "bob.

You should only catch the exceptions that actually do mean a bad address. Your code will prevent you from seeing that one exception that says "something is horribly wrong; I hope someone sees this and does something about it; I'm going to die now; goodbye".
I knew that wouldn't be popular - but yes. Look at msdn. I guess you can always get an exotic exception say, out of memory, or something crazy like that , so I'll change it. NET isn't Java, and Microsoft gets to add exceptions over the course of time.
It would be better to fail to catch some exception that actually does imply an invalid email address, than to catch and ignore some exception that implies that something terrible is happening. I approve of your "this exception doesn't matter comment" — JJS Mar 10 at Quarkly - The opposite is true, this is the only approach that promises the email is valid in. NET, any regex you write will never be the same as this validation because eventually.
NET does it anyway. And please treat your QA's better. That one validates aman village. Points for showing your work, though. All I had to do was to change the regex. The first one in this answer is the best one I've found so far The second one is not good at all sadly.
Here this is on Regexr, looks pretty close to bullet proof? Fails on email Replace emailString, ". IgnoreCase ;. Dmitry Dmitry The first solution is straightforward, relies on a probably very well tested piece of code that all. NET programmers have access to. Good work! There are cases where library designers made a mistake and did not allow you to check for the conditions proactively. TryParse method that would have allowed you to avoid the exceptions.

IgnoreCase ; return re. AddressFamily, SocketType. Stream, ProtocolType. Tcp ; s. Connect endPt ; s. IMHO you have way too many statements inside of the "try" for you to be ignoring all exceptions with a "catch".
Any of those could fail for reasons that have nothing to do with the validity of the email address, and you won't know about it. Thanks for the heads up. John Saunders - the code is merely there as an example. I'll remove the try ChrisF: instead, think of setting a good example. You know how many people find these answers and just copy and paste code.
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. Show 4 more comments. Globalization; using System. Replace strIn, ".

Email addresses generally take a fairly standard structure e. There are, however, a wide range of other limitations. A basic email regex is built into HTML5, and uses the following expression:.
What this does is it looks for any combination of A-Z both upper and lowercase and numbers, and allowing a few specific special characters, including:. However, there are a few specific rules, including that a special character cannot appear as the first or last character in an email address, nor can it be repeated consecutively. Other special characters not included in the above list are forbidden. For this reason, we explicitly allow only a few special characters here. Below we will provide a series of methods for validating email using regex in a variety of different programming languages.
It is worth noting that PHP has a built-in method for validating email addresses. You can do this using the following:. Below is one method for handling this. Using Go, you can import a few libraries to make sure that this process happens correctly. Here is a variation on the standard regex expression that we have been using:. Java requires that you go through a few extra steps but offers a few useful features such as the ability to search for a string use a case insensitivity pattern.
