Question

当我运行此代码时，出现错误：

System.Net.Mail.SmtpException：发送邮件失败。 ---＆GT; System.Net.WebException：无法连接到远程服务器 ---＆GT; System.Net.Sockets.SocketException：连接尝试失败，因为连接方在一段时间后没有正确响应时间或已建立的连接因连接的主机而失败未能回应65.55.163.152:587

代码：

static void Main(string[] args) 
{
    string smtpAddress = "smtp.live.com";
    int portNumber = 587;
    bool enableSSL = true;
    string emailFrom = "xxxxx@hotmail.co.uk";
    string password = "xxxxxxxxxxx";
    string emailTo = "myname@businessemail.co.uk";
    string subject = "Daily Email Check";
    string body = "Email reached business exchange server from an external hotmail email account";

    using (MailMessage mail = new MailMessage())
    {
        mail.From = new MailAddress(emailFrom);
        mail.To.Add(emailTo);
        mail.Subject = subject;
        mail.Body = body;
        mail.IsBodyHtml = false;

        try 
        {
            using (SmtpClient smtp = new SmtpClient(smtpAddress, portNumber))
            {
                smtp.Credentials = new NetworkCredential(emailFrom, password);
                smtp.EnableSsl = enableSSL;
                smtp.Send(mail);
            }
        }
        catch (Exception e)
        {
            Console.WriteLine("Error\n\n {0}", e);
            Console.ReadKey();
        }
    }
}

试试这个;

 using System.Net.Mail;

...

MailMessage mail = new MailMessage("xxxxx@hotmail.co.uk", "myname@businessemail.co.uk");
SmtpClient client = new SmtpClient();
client.Port = 25;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Host = "smtp.live.com";
mail.Subject = "Daily Email Check";
mail.Body = "Email reached business exchange server from an external hotmail email account";
client.Send(mail);

无法通过c＃从hotmail发送电子邮件
