在公司如果有架設SMTP(外送郵件伺服器)，使用 System.Net.Mail.SmtpClient組件以程式碼發送通知Email將變成是很簡單的事情； 本範例將實作一段在ASP.NET MVC5利用WebConfig的SMTP設定來發送Email的功能。

▋Web config

<configuration>  <system.net>     <mailSettings>       <smtp from="mail@xxxx.com">         <network defaultCredentials="false" host="smtp.xxxx.com" password="xxxx" port="25" userName="mail@xxxx.com"/>       </smtp>     </mailSettings>   </system.net> </configuration>

注意 defaultCredentials參數的設定方式： (MSDN)

True : 以預設登入使用者做認證。

False : 指定認證的帳號/密碼。

如果不使用WebConfig，也可以直接設定在代碼中實現配置。

SmtpClient mySMTP = new SmtpClient(); //如果smtpHost是指向localhost的話，則DeliveryMethod為PickupDirectoryFromIis #region SmtpClient (localhost) //mySMTP.Host = "localhost"; //mySMTP.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis; //mySMTP.PickupDirectoryLocation = @"C:\Inetpub\mailroot\Pickup"; #endregion //如果smtpHost是指向遠端主機的話，則DeliveryMethod為Network，可增加認證資料 #region SmtpClient (network) mySMTP.Host = "smtp.xxxx.com"; var mailCredentialAccount = @"domain\AD_Account"; var mailCredentialPassword = @"XXXXXX"; mySMTP.DeliveryMethod = SmtpDeliveryMethod.Network; mySMTP.Credentials = new System.Net.NetworkCredential(mailCredentialAccount, mailCredentialPassword); #endregion

▋Back-end

Controller : Post back action

[HttpPost] public ActionResult Index(VmEmailMsg viewModel) {             #region 建立MailMessage物件             MailMessage msg = new MailMessage();             msg.To.Add(viewModel.ToMailAddr);             msg.From = new MailAddress(                 viewModel.FromMailAddr, viewModel.FromName, System.Text.Encoding.UTF8);             msg.Subject = viewModel.Subject;             msg.SubjectEncoding = Encoding.UTF8;             msg.Body = viewModel.MailBody;             msg.BodyEncoding = Encoding.UTF8;             msg.IsBodyHtml = true;             msg.Priority = MailPriority.Low; //Mail priority             #endregion             #region SmtpClient (network)             SmtpClient smtpClient = new SmtpClient();             //Setup the NetworkCredential fot SMTP             //smtpClient.Host = this._smtpHost;             //var mailCredentialAccount = this._account;             //var mailCredentialPassword = this._pwd;             //smtpClient.Credentials = new System.Net.NetworkCredential(mailCredentialAccount, mailCredentialPassword);             smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;             smtpClient.Send(msg);             #endregion             return View(viewModel); }
