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( L"{0} = {1}", d->Key, d->Value );
}

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.
