Question

如何使用C＃发送多个带有名称的电子邮件地址？目前，我需要从数据库中加载名称和电子邮件地址并发送。

所以我应该先创建一个字符串数组来存储名称和电子邮件地址吗？
然后我如何发送电子邮件？必须为多个邮件地址使用MailMessages（）或MailAddress吗？

我的代码

while (sdrReader.Read())
{      
    ReceiverName = sdrReader["Name"].ToString();
    ReceiverEmail = sdrReader["EmailAddress"].ToString();           
}

// Mail to Add，在这里我想获取多个电子邮件名称和地址，然后发送它们。

mail.To.Add(new MailAddress(ReceiverEmail, ReceiverName));



sSQL = @"SELECT * FROM EmailSystem";

            try
            {
                scConnection.Open();
                scCommand = new SqlCommand(sSQL, scConnection);
                sdrReader = scCommand.ExecuteReader();

                while (sdrReader.Read())
                {

                        ReceiverName = sdrReader["Name"].ToString();
                        ReceiverEmail = sdrReader["EmailAddress"].ToString();

                }
            }



try
            {
                // Instance of Mail Server
                MailMessage mail = new MailMessage();

                // Instance of SMTP Server
                SmtpClient server = new SmtpClient(smtpAddress);


                mail.To.Add(new MailAddress(ReceiverEmail, ReceiverName));            
            }

这是您可能用来实现目标的草图。我没有触及数据库连接，我希望您检查过可以从数据库中读取数据。如果您有更多问题，请不要犹豫。

// define the body of your mail
var message = new MailMessage
{
    From = new MailAddress("foo@gmail.com", "John Doe"),
    Subject = "Please don't spam me",
    Body = "I will be very angry if you send me spam."
};

// if you don't use gmail, then you have to specify your own settings!!!
var client = new SmtpClient("smtp.gmail.com", 587)
{
    EnableSsl = true,
    Credentials = new NetworkCredential("foo@gmail.com", "superPassword")
};

// I skipped the creation of connection and command.
// Don't forget to call Dispose when you finish to work with database.
while (sdrReader.Read())
{
    var to = new MailAddress(sdrReader["EmailAddress"].ToString(),
                             sdrReader["Name"].ToString());
    message.To.Add(to);
}

client.Send(message);

使用数据集或数据表而不是数据读取器，并为每个值迭代值。
