发送电子邮件从一定义SQL服务器上报服务的提供扩展

Question

我已经开发了自己的递延用于报告服务2005年，将这个与我们的SaaS营销方案。

它需要所订购，和需要的快照该报告有一个定义设定的参数。然后呈现的报告，发送电子邮件链接和该报告附XLS。

一切正常，直到的邮件递送...

这是我的代码发送电子邮件:

 public static List<string> SendMail(SubscriptionData data, Stream reportStream, string reportName, string smptServerHostname, int smtpServerPort)
{
  List<string> failedRecipients = new List<string>();

  MailMessage emailMessage = new MailMessage(data.ReplyTo, data.To);
  emailMessage.Priority = data.Priority;
  emailMessage.Subject = data.Subject;
  emailMessage.IsBodyHtml = false;
  emailMessage.Body = data.Comment;

  if (reportStream != null)
  {
    Attachment reportAttachment = new Attachment(reportStream, reportName);
    emailMessage.Attachments.Add(reportAttachment);
    reportStream.Dispose();
  }

  try
  {
    SmtpClient smtp = new SmtpClient(smptServerHostname, smtpServerPort);

    // Send the MailMessage
    smtp.Send(emailMessage);
  }
  catch (SmtpFailedRecipientsException ex)
  {
    // Delivery failed for the recipient. Add the e-mail address to the failedRecipients List
    failedRecipients.Add(ex.FailedRecipient);
  }
  catch (SmtpFailedRecipientException ex)
  {
    // Delivery failed for the recipient. Add the e-mail address to the failedRecipients List
    failedRecipients.Add(ex.FailedRecipient);
  }
  catch (SmtpException ex)
  {
    throw ex;
  }
  catch (Exception ex)
  {
    throw ex;
  }

  // Return the List of failed recipient e-mail addresses, so the client can maintain its list.
  return failedRecipients;
}

值SmtpServerHostname是localhost，并口为25。

我veryfied，实际上我可以发送邮件，通过使用Telnet。和它的工作。

这里是错误消息我得从SSR:

年!的通知!4!08/28/2008-11:26:17::通知6ab32b8d-296e-47a2-8d96-09e81222985c完成。成功：假，状况：异常的信息：未发送的邮件。堆栈跟踪:在MyDeliveryExtension.MailDelivery.SendMail(SubscriptionData数据，流reportStream，串reportName，串smptServerHostname,Int32smtpServerPort)在C:\inetpub\wwwroot\CustomReporting\MyDeliveryExtension\MailDelivery.cs:line 48 在MyDeliveryExtension.MyDelivery.提供(通知通知)在C:\inetpub\wwwroot\CustomReporting\MyDeliveryExtension\MyDelivery.cs:line 153,DeliveryExtension:我送货，报告：点击的发展，试图1 年!dbpolling!4!08/28/2008-11:26:17::NotificationPolling完成处理项目6ab32b8d-296e-47a2-8d96-09e81222985c

这可能与信任/代码的访问权的安全？

我的递延长被授予完全的信任rssrvpolicy.配置：

   <CodeGroup 
    class="UnionCodeGroup"
    version="1"
    PermissionSetName="FullTrust"
    Name="MyDelivery_CodeGroup"
    Description="Code group for MyDelivery extension">
    <IMembershipCondition class="UrlMembershipCondition" version="1" Url="C:\Program Files\Microsoft SQL Server\MSSQL.2\Reporting Services\ReportServer\bin\MyDeliveryExtension.dll" />
   </CodeGroup> 

可以信任是一个问题，在这里？

另一种理论：SQL服务器和固态继电器安装在安全方面的当地系统。我是正确的，或是这种服务的帐户受限制的访问网络的任何资源？即使它自己的SMTP Server?

我试图改变所有SQL服务器服务的登录管理员-但还是没有任何成功。

我还想记录上SMTP server在我的代码，通过proviiding:NetworkCredential("管理员","password")和也NetworkCredential("管理员"、"密码"、"MyRepServer")

谁能帮帮这里吗？

Answer 1

什么是：

at MyDeliveryExtension.MailDelivery.SendMail(SubscriptionData data, Stream reportStream, String reportName, String smptServerHostname, Int32 smtpServerPort) 
  in C:\inetpub\wwwroot\CustomReporting\MyDeliveryExtension\MailDelivery.cs:line 48 

at MyDeliveryExtension.MyDelivery.Deliver(Notification notification) 
  in C:\inetpub\wwwroot\CustomReporting\MyDeliveryExtension\MyDelivery.cs:line 153

你也似乎是处理该报告流，但是，应该通过什么打开这一流的，不是你的方法(这不是显而易见的是，将流处置)。

你失去的一部分，栈跟踪由于你怎么重新再扔例外情况。不要扔前变，只是把是不够的。

试试这个调整：

public static List<string> SendMail(SubscriptionData data, Stream reportStream, string reportName, string smptServerHostname, int smtpServerPort)
{
  List<string> failedRecipients = new List<string>();

  MailMessage emailMessage = new MailMessage(data.ReplyTo, data.To) {
      Priority = data.Priority,
      Subject = data.Subject,
      IsBodyHtml = false,
      Body = data.Comment
  };

  if (reportStream != null)
    emailMessage.Attachments.Add(new Attachment(reportStream, reportName));

  try
  {
      SmtpClient smtp = new SmtpClient(smptServerHostname, smtpServerPort);

      // Send the MailMessage
      smtp.Send(emailMessage);
  }
  catch (SmtpFailedRecipientsException ex)
  {
    // Delivery failed for the recipient. Add the e-mail address to the failedRecipients List
    failedRecipients.Add(ex.FailedRecipient);

    //are you missing a loop here? only one failed address will ever be returned
  }
  catch (SmtpFailedRecipientException ex)
  {
    // Delivery failed for the recipient. Add the e-mail address to the failedRecipients List
    failedRecipients.Add(ex.FailedRecipient);
  }

  // Return the List of failed recipient e-mail addresses, so the client can maintain its list.
  return failedRecipients;
}

Answer 2

我试图删除的reportStream附件：

  //if (reportStream != null)    
     //emailMessage.Attachments.Add(new Attachment(reportStream, reportName));

现在它工作正常。

所以它是什么做的reportStream.

Answer 3

后打打闹闹的tunctionallity得到reportStream，我能够解决邮件发送的问题。

错不在SendMail方法，但somewehere人。唯一的例外是扔在这方面，SendMail虽然。鸡奸!

Answer 4

这就是为什么你要避免：

catch (Exception ex)
{
    throw ex;
}

因为这基本上你的斗篷除外，在新的一个。

如果你使用：

catch (Exception ex)
{
    throw; //note: no ex
}

它保持原来的例外和堆踪。

Answer 5

FileStream m_fileStream = null;

m_files = notification.Report.Render(format, null);
RenderedOutputFile m_renderedOutputFile = m_files[0];
m_fileStream = new FileStream(fileName, FileMode.Create, FileAccess.Write);
m_renderedOutputFile.Data.Seek((long)0, SeekOrigin.Begin);
byte[] arr = new byte[(int)m_renderedOutputFile.Data.Length + 1];

m_renderedOutputFile.Data.Read(arr, 0, (int)m_renderedOutputFile.Data.Length);

m_fileStream.Write(arr, 0, (int)m_renderedOutputFile.Data.Length);

m_fileStream.Close();
