Parsing email addresses

I need to parse a string like this :

<email@domain.com>,"first name" <email@domain.com>,"firstname lastname" <email@domain.com>, "firstname, lastname" <email@domain.com>,email2@domain.com

So basically, I need to get all emails, and of course the corresponding name if any.

The problem is in the fourth email. You see, the guy put a , in his name, so parsing using .Split(',') will not work.

I'm searching for a solution to be able to get both name and address in all cases.

Thanks  a lot!

This will work. But I will post a simpler one later

string input = "<email@domain.com>,\"first name\" <email@domain.com>,\"firstname lastname\" <email@domain.com>, \"firstname, lastname\" <email@domain.com>,email2@domain.com";
            MatchCollection matches = Regex.Matches(input, "(\"(?<name>.+?)\")*\\s*<?(?<email>[a-zA-Z][\\w\\.-_]*[a-zA-Z0-9]@[a-zA-Z0-9][\\w\\.-_]*[a-zA-Z0-9]\\.[a-zA-Z][a-zA-Z\\.]*[a-zA-Z])>?");
            foreach (Match m in matches)
            {
                Console.Write("Name: " + m.Groups["name"].Value + "       ");
                Console.WriteLine("Email: " + m.Groups["email"].Value);
            }

string input = "<email@domain.com>,\"first name\" <email@domain.com>,\"firstname lastname\" <email@domain.com>, \"firstname, lastname\" <email@domain.com>,email2@domain.com";
 MatchCollection matches = Regex.Matches(input, "(\"(?<name>.+?)\")*\\s*<?(?<email>[^<>,\"\\s]+)>?");
 foreach (Match m in matches)
 {
      Console.Write("Name: " + m.Groups["name"].Value + "       ");
      Console.WriteLine("Email: " + m.Groups["email"].Value);
  }

This is a simpler version. But previous regex will validate the email format. This one won't
