Question

I am using RegularExpressionValidator to validate multiple email addresses seprated by a comma “,“

My below expression works fine for this requirment:

"((\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*)*([,])*)*"

Requirment is this expression should be able to handle space after comma in email addresses.

For example my current expression work file for [e-mail],[e-mail]
but what it do not do is [e-mail], [e-mail]

I understand there can be many solutions but in my snario best is to enhance this expression.

Please guide me

Answer 1

Here is my suggestion:

((\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*)*([, ])*)*

That will accept blanks between the e-mail addresses
