Beispiele

Im folgenden Codebeispiel wird der Wert der -Eigenschaft festgelegt, um einen Namen für eine Datei anzugeben, die als Stream angefügt wird.

// The following example sends a summary of a log file as the message
// and the log as an email attachment.
static void SendNamedErrorLog( String^ server, String^ recipientList )
{
   
   // Create a message from logMailer@contoso.com to recipientList.
   MailMessage^ message = gcnew MailMessage( L"logMailer@contoso.com",recipientList );
   message->Subject = L"Error Log report";
   String^ fileName = L"log.txt";
   
   // Get the file stream for the error log.
   // Requires the System.IO namespace.
   FileStream^ fs = gcnew FileStream( fileName,FileMode::Open,FileAccess::Read );
   StreamReader^ s = gcnew StreamReader( fs );
   int errors = 0;
   while ( s->ReadLine() != nullptr )
   {
      
      // Process each line from the log file here.
      errors++;
   }

   message->Body = String::Format( L"{0} errors in log as of {1}", errors, DateTime::Now );
   
   // Close the stream reader. This also closes the file.
   s->Close();
   
   // Re-open the file at the beginning to make the attachment.
   fs = gcnew FileStream( fileName,FileMode::Open,FileAccess::Read );
   
   // Make a ContentType indicating that the log data
   // that is attached is plain text and is named.
   ContentType^ ct = gcnew ContentType;
   ct->MediaType = MediaTypeNames::Text::Plain;

   client->Send( message );
   data->~Attachment();
   client->~SmtpClient();
   
   // Close the log file.
   fs->Close();
   return;

        errors, DateTime.Now);

Hinweise

Im folgenden Beispiel für einen Content-Type-Header ist "data.xyz"der Wert der Name -Eigenschaft .

content-type: application/x-myType; name=data.xyz

Eine Grammatik, die die Syntax des Content-Type-Headers detailliert beschreibt, wird in RFC 2045 Abschnitt 5.1 beschrieben, der unter https://www.ietf.orgverfügbar ist.

Wenn Sie Inhalt für ein Attachment als oder StreamStringangeben, können Name Sie verwenden, um den Namen der Datei festzulegen, die den Inhalt im System des Empfängers speichert.
