範例

下列程式碼範例會重新傳送未傳遞的電子郵件訊息, 因為信箱忙碌或無法使用。The following code example resends an email message that was not delivered because a mailbox was busy or unavailable.

static void RetryIfBusy( String^ server )
{
   MailAddress^ from = gcnew MailAddress( L"ben@contoso.com" );
   MailAddress^ to = gcnew MailAddress( L"jane@contoso.com" );
   MailMessage^ message = gcnew MailMessage( from,to );
   
   // message.Subject = "Using the SmtpClient class.";
   message->Subject = L"Using the SmtpClient class.";
   message->Body = L"Using this feature, you can send an email message from an application very easily.";
   
   // Add a carbon copy recipient.
   MailAddress^ copy = gcnew MailAddress( L"Notifications@contoso.com" );
   message->CC->Add( copy );
   SmtpClient^ client = gcnew SmtpClient( server );
   
   // Include credentials if the server requires them.
   client->Credentials = dynamic_cast<ICredentialsByHost^>(CredentialCache::DefaultNetworkCredentials);
   Console::WriteLine( L"Sending an email message to {0} using the SMTP host {1}.", to->Address, client->Host );
   try
   {
      client->Send( message );
   }
   catch ( SmtpFailedRecipientsException^ ex ) 
   {
      for ( int i = 0; i < ex->InnerExceptions->Length; i++ )
      {
         SmtpStatusCode status = ex->InnerExceptions[ i ]->StatusCode;
         if ( status == SmtpStatusCode::MailboxBusy || status == SmtpStatusCode::MailboxUnavailable )
         {
            Console::WriteLine( L"Delivery failed - retrying in 5 seconds." );
            System::Threading::Thread::Sleep( 5000 );
            client->Send( message );
         }
         else
         {
            Console::WriteLine( L"Failed to deliver message to {0}", ex->InnerExceptions[ i ] );
         }

      }
   }
   catch ( Exception^ ex )
   {
       Console::WriteLine(L"Exception caught in RetryIfBusy(): {0}", 
                     ex->ToString() );
   }
   finally
   {
      client->~SmtpClient();
   }
}


public static void RetryIfBusy(string server)
{
	MailAddress from = new MailAddress("ben@contoso.com");
	MailAddress to = new MailAddress("jane@contoso.com");
	MailMessage message = new MailMessage(from, to);
	// message.Subject = "Using the SmtpClient class.";
	message.Subject = "Using the SmtpClient class.";
	message.Body = @"Using this feature, you can send an email message from an application very easily.";
	// Add a carbon copy recipient.
	MailAddress copy = new MailAddress("Notifications@contoso.com");
	message.CC.Add(copy);
	SmtpClient client = new SmtpClient(server);
	// Include credentials if the server requires them.
	client.Credentials = (ICredentialsByHost)CredentialCache.DefaultNetworkCredentials;
	Console.WriteLine("Sending an email message to {0} using the SMTP host {1}.",
		 to.Address, client.Host);
	try
	{
		client.Send(message);
	}
	catch (SmtpFailedRecipientsException ex)
	{
		for (int i = 0; i < ex.InnerExceptions.Length; i++)
		{
			SmtpStatusCode status = ex.InnerExceptions[i].StatusCode;
			if (status == SmtpStatusCode.MailboxBusy ||
				status == SmtpStatusCode.MailboxUnavailable)
			{
				Console.WriteLine("Delivery failed - retrying in 5 seconds.");
				System.Threading.Thread.Sleep(5000);
				client.Send(message);
			}
			else
			{
				Console.WriteLine("Failed to deliver message to {0}", 
				    ex.InnerExceptions[i].FailedRecipient);
			}
		}
	}
          catch (Exception ex)
          {
              Console.WriteLine("Exception caught in RetryIfBusy(): {0}", 
                      ex.ToString() );
          }
      }

備註

InnerExceptions屬性包含嘗試傳送電子郵件時收到的例外狀況。The InnerExceptions property contains the exceptions received while attempting to send email. 電子郵件可能已成功傳遞給某些收件者。The email might have been successfully delivered to some of the recipients.
