How to validate multiple email id's?

Question

I am working on sending email using smtp in mvc. I am able to validate single email address. But i want to validate multiple email addresses separated by semicolon (;). Here is regular expression which i am using

@"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}" +
                            @"\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\" +
                            @".)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$"

Instead of creating an even more complex regex (a proper email validating regex is already far complex enough), why not just split the string and validate each address individually? For example:

bool isValid = true;
foreach (email in stringOfEmails.Split(';'))
{
    // validate the individual email address
    // if any fails, set `isValid` to `false` and break
}

You can wrap that up into a method on a utility class, or create an extension, if you prefer.
