i am using \w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)* regex to validate email id in my
asp.net web application and this regular expression is provided by visual studio 2010
in their regular expression validator but if i entered 99@99.com then it is not showing any
error message.
so i just want to confirm that is it a valid email id?
Yes, it’s valid. RFC5321 and 5322 (section 3.4.1 specifically) define the local and domain parts of the email address, and both of them allow digits in any position.
Wikipedia has some more details.
