使用System.Net.Mail

MailMessage msgMail = new MailMessage(); 

    MailMessage myMessage = new MailMessage(); 
    myMessage.From = new MailAddress("sender's email","sender`s name and surname"); 
    myMessage.To.Add("recipient's email"); 
    myMessage.Subject = "Subject"; 
    myMessage.IsBodyHtml = true; 

    myMessage.Body = "Message Body"; 


    SmtpClient mySmtpClient = new SmtpClient(); 
    System.Net.NetworkCredential myCredential = new System.Net.NetworkCredential("email", "password"); 
    mySmtpClient.Host = "your smtp host address"; 
    mySmtpClient.UseDefaultCredentials = false; 
    mySmtpClient.Credentials = myCredential; 
    mySmtpClient.ServicePoint.MaxIdleTime = 1; 

    mySmtpClient.Send(myMessage); 
    myMessage.Dispose(); 

更新的用户越来越以下错误

{ “A插座操作尝试无法访问网络208.91.199.230:25”}和错误代码是10051

的错误10051是当目标网络或主机服务器无法到达出现一个套接字错误。错误可能是由于路由器的错误配置，Internet断开连接或防火墙阻止操作导致的。大多在试图生成Internet控制消息协议（ICMP），并与错误配置简单邮件传输协议（SMTP）连接时发生此错误。这个错误也表明，使用Windows的软件配置为传送到路由器，因为10065错误，如果Windows没有设置链接到一个路由器，而不是出现。

你应该确保网络路径正确，计算机没有运行两个软件防火墙和目标计算机未关闭。

发送邮件：

var smtp = new System.Net.Mail.SmtpClient(); 
{ 
    smtp.Host = "smtp.gmail.com"; 
    smtp.Port = 587; 
    smtp.EnableSsl = true; 
    smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network; 
    smtp.Credentials = new NetworkCredential(fromAddress, fromPassword); 
    smtp.Timeout = 20000; 
} 
// Passing values to smtp object 
smtp.Send(fromAddress, toAddress, subject, body);

使用此代码发送邮件，这是经过测试的代码。

public static void SendMailMessage(string from, string to, string bcc, string cc, string subject, string body) 
    { 
     // Instantiate a new instance of MailMessage 
     MailMessage mMailMessage = new MailMessage(); 

     // Set the sender address of the mail message 
     mMailMessage.From = new MailAddress(from); 
     // Set the recepient address of the mail message 
     mMailMessage.To.Add(new MailAddress(to)); 

     // Check if the bcc value is null or an empty string 
     if ((bcc != null) && (bcc != string.Empty)) 
     { 
      // Set the Bcc address of the mail message 
      mMailMessage.Bcc.Add(new MailAddress(bcc)); 
     }  // Check if the cc value is null or an empty value 
     if ((cc != null) && (cc != string.Empty)) 
     { 
      // Set the CC address of the mail message 
      mMailMessage.CC.Add(new MailAddress(cc)); 
     }  // Set the subject of the mail message 
     mMailMessage.Subject = subject; 
     // Set the body of the mail message 
     mMailMessage.Body = body; 

     // Set the format of the mail message body as HTML 
     mMailMessage.IsBodyHtml = true; 
     // Set the priority of the mail message to normal 
     mMailMessage.Priority = MailPriority.Normal; 

     // Instantiate a new instance of SmtpClient 
     SmtpClient mSmtpClient = new SmtpClient(); 
     // Send the mail message 
     mSmtpClient.Host = "smtp.gmail.com"; //Or Your SMTP Server Address 
     mSmtpClient.Credentials = new System.Net.NetworkCredential 
      ("YourEmail@gmail.com", "Password"); 
     //Or your Smtp Email ID and Password 
     mSmtpClient.EnableSsl = true; 

     mSmtpClient.Send(mMailMessage); 
    }

注：我一直在试图通过我的ISP的邮件服务器，但没有成功发送电子邮件 - 以下所有我能找到这些论坛上的建议。我刚刚发现，如果我不尝试更改默认凭据设置，它将正常工作。如果我包括：client.UseDefaultCredentials = true;或client.UseDefaultCredentials = false;在我的代码中，然后我会从服务器获取登录失败消息。通过不包括，它运作良好。
