The following code example displays an error message to the console when an SmtpException is thrown.

static void CreateMessageWithAttachment3( String^ server, String^ to )
{
   
   // Specify the file to be attached and sent.
   // This example assumes that a file named data.xls exists in the
   // current working directory.
   String^ file = L"data.xls";
   
   // Create a message and set up the recipients.
   MailMessage^ message = gcnew MailMessage( L"[email protected]",to,L"Quarterly data report",L"See the attached spreadsheet." );
   
   // Create  the file attachment for this email message.
   Attachment^ data = gcnew Attachment("Qtr3.xls");
   
   
   // Add time stamp information for the file.
   ContentDisposition^ disposition = data->ContentDisposition;
   disposition->CreationDate = System::IO::File::GetCreationTime( file );
   disposition->ModificationDate = System::IO::File::GetLastWriteTime( file );
   disposition->ReadDate = System::IO::File::GetLastAccessTime( file );
   
   // Add the file attachment to this email message.
   message->Attachments->Add( data );
   
   //Send the message.
   SmtpClient^ client = gcnew SmtpClient( server );
   
   // Add credentials if the SMTP server requires them.
   client->Credentials = dynamic_cast<ICredentialsByHost^>(CredentialCache::DefaultNetworkCredentials);
   
   // Notify user if an error occurs.
   try
   {
      client->Send( message );
   }
   catch ( SmtpException^ e ) 
   {
      Console::WriteLine( L"Error: {0}", e->StatusCode );

Remarks

The values in the SmtpStatusCode enumeration specify reply status values sent by a Simple Mail Transfer Protocol (SMTP) server. The SmtpException and SmtpFailedRecipientsException classes contain StatusCode properties that return SmtpStatusCode values.

SMTP is defined in RFC 2821 available at https://www.ietf.org.
