Examples

The following code example demonstrates calling this method.

static void CreateMessageWithAttachment( String^ server )
{
   
   // 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"jane@contoso.com",L"ben@contoso.com",L"Quarterly data report.",L"See the attached spreadsheet." );
   
   // Create  the file attachment for this email message.
   Attachment^ data = gcnew Attachment(file, MediaTypeNames::Application::Octet);
   
   // 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 = CredentialCache::DefaultNetworkCredentials;
   client->Send( message );
   
   // Display the values in the ContentDisposition for the attachment.
   ContentDisposition^ cd = data->ContentDisposition;
   Console::WriteLine( L"Content disposition" );
   Console::WriteLine( cd );
   Console::WriteLine( L"File {0}", cd->FileName );
   Console::WriteLine( L"Size {0}", cd->Size );
   Console::WriteLine( L"Creation {0}", cd->CreationDate );

   IEnumerator^ myEnum1 = cd->Parameters->GetEnumerator();
   while ( myEnum1->MoveNext() )
   {
      DictionaryEntry^ d = safe_cast<DictionaryEntry^>(myEnum1->Current);
      Console::WriteLine( L"{0} = {1}", d->Key, d->Value );
   }

   data->~Attachment();
   client->~SmtpClient();
}

Remarks

The string returned by the ToString method is the Content-Disposition header.

The Content-Disposition header is described in RFC 2183 available at https://www.ietf.org.
