Question

我正在尝试使用SMTP客户端发送电子邮件（例如gmail smtp）。我知道如何发送一封电子邮件，但我想要一些自动化。

我想要的：我想发送25封电子邮件，一个smtp，然后更改smtp（用户名和密码。）例如，使用username1密码的前25封电子邮件其他25封电邮与suername2密码2

    SmtpClient client = new SmtpClient();
    client.Port = 587;
    client.Host = "smtp.gmail.com";
    client.EnableSsl = true;
    client.Timeout = 10000;
    client.DeliveryMethod = SmtpDeliveryMethod.Network;
    client.UseDefaultCredentials = false;
    client.Credentials = new System.Net.NetworkCredential("user@gmail.com","password");

    MailMessage mm = new MailMessage("donotreply@domain.com", "sendtomyemail@domain.co.uk", "test", "test");
    mm.BodyEncoding = UTF8Encoding.UTF8;
    mm.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;

    client.Send(mm);

我不熟悉，你只能用谷歌smtp一次发送一封电子邮件，但如果你正在寻找可以在smtp之间切换的东西，这样的事情可能会这样做：

public void MyMailFunction()
    {
        while (true)
        {
            bool SwitchSMTP = false;

            using (var db = whatEverContext())
            {
                var q = from s in db.mail select s;
                var myList = q.ToList.Take(25);
                if (myList.Count() == 0)
                {
                    break; 
                }

                if (!SwitchSMTP)
                    {
                        SendMails(myList, 25, "smtp.gmail.com", "myusername", "mypassword");
                        SwitchSMTP = true;

                    }
                    else
                    {
                        SendMails(myList, 25, "smtp.gmail.com", "myusername", "mypassword");
                        SwitchSMTP = false;
                    }


            }

        }
    }

    internal void SendMails(IEnumerable<Mail> myList, int port, string host, string username, string password)
    {
        SmtpClient client = new SmtpClient();
        client.Port = port;
        client.Host = host;
        client.EnableSsl = true;
        client.Timeout = 10000;
        client.DeliveryMethod = SmtpDeliveryMethod.Network;
        client.UseDefaultCredentials = false;
        client.Credentials = new System.Net.NetworkCredential(username, password);

        foreach (var m in myList)
        {

            MailMessage mm = new MailMessage("donotreply@domain.com", "sendtomyemail@domain.co.uk", "test", "test");
            mm.BodyEncoding = UTF8Encoding.UTF8;
            mm.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;
            client.Send(mm);
        }

        client.Dispose();
    }

我还没有编译代码，但这个想法可能就是你在寻找什么？
