尝试发送邮件 C# 时出现 smtp 异常

Question

我正在尝试使用此代码通过 SmtpClient 发送电子邮件

var client = new SmtpClient("smtp.gmail.com", 465)
        {
            Credentials = new NetworkCredential("***@gmail.com", "password"),
            EnableSsl = true,
        };
        client.Send("***@gmail.com", "***@gmail.com", "test", "testbody");

我得到的是 smtpException "无法发送消息"。

System.Net.Mail.SmtpException: Message could not be sent. ---> System.Exception:Connectionclosed at System.Net.Mail.SmtpClient.Read () [0x000f9] in /private/tmp/source/bockbuild-mono-

我在 Mac (OSX 10.9.2) 上使用 Mono

我的凭据和主机/端口是正确的。 也许我需要以某种方式通过我的 gmail 帐户启用它？ 谢谢！

Use:

using System.Net;
using System.Net.Mail;

var fromAddress = new MailAddress("from@gmail.com", "From Name");
var toAddress = new MailAddress("to@example.com", "To Name");
const string fromPassword = "fromPassword";
const string subject = "Subject";
const string body = "Body";

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
                     })
{
    smtp.Send(message);
}
