Email validating regular expression
That's why I check the general syntax with a simple regular expression first and check more specific options with other functions afterwards.This may not be not the best technical solution, but this way I'm way more flexible and faster. Write(email " is incorrect"); For more info go read about it here: C# – Email Regular Expression Also, this checks for RFC validity based on email syntax, not for whether the email really exists.
Ignore Case); Why not use EF6 attribute based e-mail validation?
To fix this problem, you implement an activation system where, after registering, I am sent an email with a link I must click.
This is to verify that I actually own that email address before my account is activated.
If (like me when I first saw this) you AREN’T experienced at Regex, it takes a while to parse. The local string (the part of the email address that comes before the @) can contain any of these characters: is a valid email address. For this reason, for a time I began running any email address against the following regular expression instead: Simple, right? This is often the most I do and, when paired with a confirmation field for the email address on your registration form, can alleviate most problems with user error.
They can get ridiculously convoluted as in the case above and, according to the specification, are often too strict anyway.
