How can I include multiple recipients in a gmail email message?

I've got this working code to send an email using my gmail account:

public static void SendEmail(string fullName, string toEmail, string HH, string HHEmailAddr)
{
    var fromAddress = new MailAddress(FROM_EMAIL, FROM_EMAIL_NAME);
    var toAddress = new MailAddress(toEmail, fullName);
    var toAddressHH = new MailAddress(HHEmailAddr, HH);
    string fromPassword = GMAIL_PASSWORD;

    List<String> htmlBody = new List<string>
    {
        "<html><body>",
        . . .
        "</body></html>"
    };
    var body = string.Join("", htmlBody.ToArray());

    var smtp = new SmtpClient
    {
        Host = "smtp.gmail.com",
        Port = 587,
        EnableSsl = true,
        DeliveryMethod = SmtpDeliveryMethod.Network,
        UseDefaultCredentials = false,
        Credentials = new NetworkCredential(fromAddress.Address, fromPassword)
    };
    using (var message = new MailMessage(fromAddress, toAddress)
    {
        Subject = subject,
        Body = body,
        IsBodyHtml = true
    })
    {
        smtp.Send(message);
    }
}

The problem is that I want to send the email to two recipients, not one. I can theoretically add another message to the end of that code like so:

    . . .
    using (var messageHH = new MailMessage(fromAddress, toAddressHH)
    {
        Subject = subject,
        Body = body,
        IsBodyHtml = true
    })
    {
        smtp.Send(messageHH);
    }
}

...sending two emails from one code block, but what I really want to do is something like this:

List<MailAddress> recipients = new List<MailAddress>();
recipients.Add(toAddress);
recipients.Add(toAddressHH);
. . .
using (var message = new MailMessage(fromAddress, recipients)

...but there seems to no such overload for MailMessage's constructor. How can I add a second recipient to the sending of an email from gmail? Both as a co-recipient and as a "CC" recipient would be nice to know.

UPDATE

If I do try the suggested:

using (var message = new MailMessage(fromAddress, toAddress)
{
    Subject = subject,
    Body = body,
    To.Add("[email protected]", "Duckbilled Platypus")
})

...I get:

Invalid initializer member declarator

..and:

The name 'To' does not exist in the current context

I get the same with the following permutation:

To.Add(new MailAddress("[email protected]", "Duckbilled Platypus"))

I had to change the "style" of declaration, but this works:

var message = new MailMessage(fromAddress, toAddress);
message.Subject = subject;
message.Body = body;
message.To.Add(new MailAddress("[email protected]", "Duckbilled Platypus"));
message.To.Add(new MailAddress("[email protected]", "Platypus 2"));
smtp.Send(message);

Looking at Microsoft's Documentation, you can see that the MailMessage.To property is a MailAddressCollection.

The MailAddressCollection has an Add() method that will append values to the collection.

With that information, you can try something like this:

messageHH.To.Add(new MailAddress("[email protected]","Recipient1 Name"));
messageHH.To.Add(new MailAddress("[email protected]","Recipient2 Name"));
messageHH.To.Add(new MailAddress("[email protected]","Recipient3 Name"));
//etc...
