System.Net.Mail.MailAddress send to multiple emails with one parameter

Question

I've just switched from the deprecated System.Web.Mail.MailAddress to System.Net.Mail.MailAddress, but it doesn't seem to be particularly flexible when passing in a parameter holding multiple addresses when using the new System.Net.Mail.MailAddress.To.Add.

string emailAdd= "[email protected]; [email protected]";

System.Net.Mail.MailAddress.To.Add(emailAdd);

In the above example, [email protected] is emailed successfully, but [email protected] is not. I really need a way to do this since my addresses are defined in another class and passed to an email() method via a parameter. I'm simply not passing five parameters for 5 separate emails. Or indeed one and splicing on my end, .Web version is proving to be way more versatile.

This question is not a duplicate of the suggested one. The answer to the "duplicate" is add them individually, I want to add multiple addresses simultaneously. Since there is a way to do this, this question is more relevant than the one I'm accused of duplicating.

Answer 1

According to MSDN, the .Add() method accepts a string of comma-delimited addresses, rather than semicolon-delimited.

Therefore either changing the parameter that you are passing in to a comma-delimited string, if possible, or adding functionality to your email method to replace the semicolons with commas should resolve the issue.
