c# - Regular expression for multiple email destinations delimited by semicolon -

i succeed regular expression single email this:

private readonly regex _regex = new regex(@"^[_a-za-z0-9-\\+]+(\\.[_a-za-z0-9-]+)*@"                                           + "[a-za-z0-9-]+(\\.[a-za-z0-9]+)*(\\.[a-za-z]{2,})$"); 

now, need make regular expression more 1 email, , delimited semicolon

test@gmail.com;test2@yahoo.com;test3@gmail.com 

i found regular expression:

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

but problem regular expression "receive" string:

h@kj.com;asds@gmail 

how can that?

thanks

let's not build regular expression more 1 because 1 complex enough, validate them individually:

foreach (var email in emaillist.split(new char[] { ';' },     stringsplitoptions.removeemptyentries)) {     // validate email } 

further, regular expressions aren't suited because user have put space, more 1 space, before or after semicolon - gets messy - , emails messy enough already.
