Question

我尝试编写用于发送带有.NET的电子邮件的代码。这就是我到目前为止所做的：

MailMessage mail = new MailMessage("mymailaddress@yahoo.com", address);
mail.Subject = subject;
mail.Body = body;
client.Host = "smtp.gmail.com"; 
client.Port = 587;
client.Send(e);

问题是我得到以下异常：

未处理的例外：System.Net.Mail.SmtpException：发送邮件失败。


System.Net.WebException：无法连接到远程服务器。


System.Net.Sockets.SocketException：连接尝试因连接方失败而失败       一段时间后未正确响应，或已建立的连接失败，因为已连接的主机未能响应173.194.66.109:587

试试这个：

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

// ...

MailAddress maFrom = new MailAddress("<address>", "<display_name>");
MailAddress maTo = new MailAddress("<address>", "<display_name>");
const string sPassword = "<password>";
const string sSubject = "<subject>";
const string sBody = "<body>";

new SmtpClient
{
    Host = "smtp.gmail.com",
    Port = 587,
    EnableSsl = true,
    DeliveryMethod = SmtpDeliveryMethod.Network,
    UseDefaultCredentials = false,
    Credentials = new NetworkCredential(maFrom.Address, sPassword)
}.Send(new MailMessage(maFrom, maTo) { Subject = sSubject, Body = sBody });

SMTP服务器不响应`SmtpClient`连接尝试。我该如何解决？
