在silverlight中創建新聞郵件

Question

對於我的silverlight項目，我創建了一個可以通過特定頁面發送的新聞郵件。

爲此，我有一個通訊服務，在這裏可以看到：

 public bool SendMail(string emailTo, string emailFrom, string msgSubject, string msgBody) 
    { 
     bool success = false; 
     try 
     { 
      MailMessage msg = new MailMessage(); 
      msg.From = new MailAddress(emailFrom); 
      msg.To.Add(new MailAddress(emailTo)); 
      msg.Subject = msgSubject; 
      msg.Body = msgBody; 
      msg.IsBodyHtml = true; 
      SmtpClient smtp = new SmtpClient(); 
      smtp.Host = "smtp.gmail.com"; // Replace with your servers IP address 
      smtp.Port = 465; 
      smtp.EnableSsl = false; 
      smtp.Send(msg); 
      success = true; 
     } 

     catch(Exception e) 
     { 
      success = false; 
     } 

     return success; 

    } 

我要求服務用下面的代碼發送郵件：

public partial class Nieuwsbrief : UserControl 
{ 
    IEnumerable<Inschrijvingen> ingeschrevenen = null; 

    public Nieuwsbrief() 
    { 
     InschrijvingenServiceClient personclient = new InschrijvingenServiceClient(); 

     personclient.getInschrijvingenCompleted += new EventHandler<getInschrijvingenCompletedEventArgs>(personclient_getInschrijvingenCompleted); 
     personclient.getInschrijvingenAsync(); 

     InitializeComponent(); 
    } 

    private void btnSubmit_Click(object sender, RoutedEventArgs e) 
    { 
     NieuwsbriefServiceClient client = new NieuwsbriefServiceClient(); 

     //foreach (Inschrijvingen person in ingeschrevenen) 
     //{ 
      client.SendMailAsync("test@gmail.com", "nieuwsbrief@ondernemersaward.be", txtSubject.Text, txtContent.Text); 
     //} 

     client.SendMailCompleted += new EventHandler<SendMailCompletedEventArgs>(client_SendMailCompleted); 
    } 

    void personclient_getInschrijvingenCompleted(object sender, getInschrijvingenCompletedEventArgs e) 
    { 
     ingeschrevenen = e.Result; 
    } 

    void client_SendMailCompleted(object sender, SendMailCompletedEventArgs e) 
    { 
     if (e.Error != null) 
      txtContent.Text = "Mail has NOT send!" + e.Error.ToString(); 
     else 
      MessageBox.Show(e.Result.ToString()); 
    } 
} 

然而，當我按下btnSubmit什麼也沒有發生，直到我關閉服務器，然後我得到以下錯誤：

Mail has NOT send!System.ServiceModel.CommunicationException: The remote server returned an error: NotFound. ---> System.Net.WebException: The remote server returned an error: NotFound. ---> System.Net.WebException: The remote server returned an error: NotFound.

    at OndernemersAward.NieuwsbriefServiceReference.NieuwsbriefServiceClient.OnEndSendMail(IAsyncResult result) 
    at System.ServiceModel.ClientBase`1.OnAsyncCallCompleted(IAsyncResult result) 

我希望有人能幫助我， 謝謝:)

Answer 1

在你的catch語句做到這一點：

catch (Exception e) 
{ //<---- Put the break point here. 

} 

您就可以看到「E」，看看爲什麼這是失敗的。

我的猜測是它的smtp.Send這是失敗的，它可以拋出a lot of exceptions，所以我不會冒險猜測哪一個！

編輯：另外，它表示「//替換爲您的服務器IP地址」，您是否將其替換爲您的服務器的IP地址？我第一次假設你發佈了演示代碼，但我想確定。

嗯，這是你的問題！ Gmail可讓您將它們用作smtp服務器。使用它們：http://www.geekzone.co.nz/tonyhughes/599。您必須將您的smtp.Port更改爲465，將smtp.Host更改爲smtp.gmail.com。這需要認證，所以去創建一個Gmail帳戶。
