Answer 1

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(); 

更新的用戶越來越以下錯誤

{ 「A插座操作嘗試無法訪問網絡208.91.199.230:25」}和錯誤代碼是10051

的錯誤10051是當目標網絡或主機服務器無法到達出現一個套接字錯誤。錯誤可能是由於路由器的錯誤配置，Internet斷開連接或防火牆阻止操作導致的。大多在試圖生成Internet控制消息協議（ICMP），並與錯誤配置簡單郵件傳輸協議（SMTP）連接時發生此錯誤。這個錯誤也表明，使用Windows的軟件配置爲傳送到路由器，因爲10065錯誤，如果Windows沒有設置鏈接到一個路由器，而不是出現。

你應該確保網絡路徑正確，計算機沒有運行兩個軟件防火牆和目標計算機未關閉。

發送郵件：

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);

使用此代碼發送郵件，這是經過測試的代碼。

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：我一直在試圖通過我的ISP的郵件服務器，但沒有成功發送電子郵件 - 以下所有我能找到這些論壇上的建議。我剛剛發現，如果我不嘗試更改默認憑據設置，它將正常工作。如果我包括：client.UseDefaultCredentials = true;或client.UseDefaultCredentials = false;在我的代碼中，然後我會從服務器獲取登錄失敗消息。通過不包括，它運作良好。
