Question

可能重复：
Unable to send an email to multiple addresses/recipients using C#

我使用下面的代码在脚本任务中发送邮件

 string MailFromName = "Admin";
            System.Net.Mail.SmtpClient mailobj = new System.Net.Mail.SmtpClient();
            System.Net.Mail.MailAddress MailFrom = new System.Net.Mail.MailAddress(MailFromEmail, MailFromName);
            System.Net.Mail.MailAddress MailTo = new System.Net.Mail.MailAddress(MailToEmail, MailToEmail);
            System.Net.Mail.MailMessage mailmsg = new System.Net.Mail.MailMessage(MailFrom, MailTo);
            mailmsg.IsBodyHtml = true;
            mailmsg.Subject = strMessageSubject;
            mailmsg.Body = strMessageBody;
            mailobj.Host = strSMTPServerName;
            mailobj.Send(mailmsg);

当我使用MailToEmail作为“myaddress@myMail.com”，即一个电子邮件地址

时工作正常

但当我在列表中有多个地址时，这不会发送任何邮件（也不会失败）

ex：“MyAdress@MyMail.com; MySecondAddress@MyMail.com”

如何解决这个问题？

编辑新代码

 string MailFromName = "Admin";
            System.Net.Mail.SmtpClient mailobj = new System.Net.Mail.SmtpClient();
            System.Net.Mail.MailAddress MailFrom = new System.Net.Mail.MailAddress(MailFromEmail, MailFromName);
            System.Net.Mail.MailAddress MailTo = new System.Net.Mail.MailAddress(MailToEmail, MailToEmail);
            System.Net.Mail.MailMessage mailmsg = new System.Net.Mail.MailMessage(MailFrom, MailTo);
            mailmsg.IsBodyHtml = true;
            mailmsg.Subject = strMessageSubject;
            mailmsg.Body = strMessageBody;
            foreach (string str in multipleToMsg)
            {
                mailmsg.To.Add(str);
            }


            mailobj.Host = strSMTPServerName;
            mailobj.Send(mailmsg);

Answer 1

您尚未显示添加收件人的确切方式。但是，要添加多个收件人，请添加到“收件人”集合：

MailMessage message = new MailMessage();
message.To.Add("sillyjoe@stackoverflow.com");

“To”是MailAddresses的集合。确保将其添加到该集合中，而不是尝试将电子邮件地址全部连接到一个MailAddress对象中。

Answer 2

根据MSDN: MailMessage Class，“To”属性是Mail Addresses的集合

所以你只需要做一些像

这样的事情

mailmsg.To.Add(new System.Net.Mail.MailAddress(MailToEmail, MailToEmail)); 
mailmsg.To.Add(new System.Net.Mail.MailAddress(MailToEmail2, MailToEmail2))

或在foreach循环中

//get email addresses into a collection called emailAdds
foreach (var emailAdd in emailAdds)
{
    mailmsg.To.Add(new System.Net.Mail.MailAddress(emailAdd, emailAdd )); 
}

Answer 3

要指定多个地址，您需要使用To属性MailAddressCollection

message.To.Add("one@example.com, one@example.com"));
message.To.Add("two@example.com, two@example.com"));

邮件不适用于多个地址
