如何在Gmail电子邮件中包含多个收件人？

Question

I've got this working code to send an email using my gmail account: 我有以下工作代码可以使用我的gmail帐户发送电子邮件：

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. 问题是我想将电子邮件发送给两个收件人，而不是一个。 I can theoretically add another message to the end of that code like so: 从理论上讲，我可以在该代码的末尾添加另一条消息，如下所示：

    . . .
    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: ...从一个代码块发送两封电子邮件，但是我真正想要做的是这样的：

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. ...但是对于MailMessage的构造函数来说似乎没有这样的重载。 How can I add a second recipient to the sending of an email from gmail? 如何在通过gmail发送电子邮件时添加第二个收件人？ Both as a co-recipient and as a "CC" recipient would be nice to know. 作为共同收件人和“ CC”收件人，都将很高兴知道。

UPDATE UPDATE

If I do try the suggested: 如果我尝试尝试建议：

using (var message = new MailMessage(fromAddress, toAddress)
{
    Subject = subject,
    Body = body,
    To.Add("dplatypus@att.net", "Duckbilled Platypus")
})

...I get: ...我得到：

Invalid initializer member declarator 无效的初始化器成员声明器

..and: ..和：

The name 'To' does not exist in the current context 名称“ To”在当前上下文中不存在

I get the same with the following permutation: 我得到以下排列相同：

To.Add(new MailAddress("dplatypus@att.net", "Duckbilled Platypus"))

Answer 1

Looking at Microsoft's Documentation , you can see that the MailMessage.To property is a MailAddressCollection. 查看Microsoft的Documentation ，您可以看到MailMessage.To属性是MailAddressCollection。

The MailAddressCollection has an Add() method that will append values to the collection. MailAddressCollection具有一个Add（）方法，该方法会将值附加到集合中。

With that information, you can try something like this: 有了这些信息，您可以尝试如下操作：

messageHH.To.Add(new MailAddress("recipient1@domain.com","Recipient1 Name"));
messageHH.To.Add(new MailAddress("recipient2@domain.com","Recipient2 Name"));
messageHH.To.Add(new MailAddress("recipient3@domain.com","Recipient3 Name"));
//etc...

Answer 2

I had to change the "style" of declaration, but this works: 我不得不更改声明的“样式”，但这可以起作用：

var message = new MailMessage(fromAddress, toAddress);
message.Subject = subject;
message.Body = body;
message.To.Add(new MailAddress("dplatypus@att.net", "Duckbilled Platypus"));
message.To.Add(new MailAddress("duckbill@att.net", "Platypus 2"));
smtp.Send(message);
