Sending emails to multiple adresses using MvcMailer

Question

I have an emails variable that contains a list of e-mail addresses of users in a role. The list is not comma-separated. Here's the code that I have at the moment:

    public virtual MvcMailMessage AdminNotification()
    {
        var userRoles = Roles.GetUsersInRole("Admin");
        var users = new List<MembershipUser>();
        var emails = new List<String>();
        foreach (var UserName in userRoles)
        {
            var user = Membership.GetUser(UserName, false);
            users.Add(user);
            emails.Add(user.Email);
        }

        return Populate(x =>
        {
            x.Subject = "AdminNotification";
            x.ViewName = "AdminNotification";
            emails.ForEach(user => x.To.Add(user.Email));
        });
    }

I get an error stating 'string' does not contain a definition for 'Email'...

What should I use instead of x.To.Add(user.Email)?

Update #1

I'm able to send out e-mails to the intended recipients, but the message body is blank. The message body has been constructed in a View. It was working before I used the code in the answer below, how can I get it working again?

Answer 1

This is how I'd rewrite it:

public virtual MvcMailMessage AdminNotification()
{
    string[] userRoles = Roles.GetUsersInRole("Admin");

    IEnumerable<string> emails =
        userRoles.Select(userName => Membership.GetUser(userName, false))
                 .Select(user => user.Email);

    var message = new MvcMailMessage {Subject = "AdminNotification", ViewName = "AdminNotification"};

    foreach (string email in emails)
    {
        message.To.Add(email);
    }
    return message;
}

I hope it helps.
