   Console::WriteLine( L"Sending an email message to {0} and {1}.", to->DisplayName, message->Bcc );
       client->Send( message );
   catch ( Exception^ ex )
       Console::WriteLine(L"Exception caught in CreateBccTestMessage(): {0}", 
                     ex->ToString() );

BCC 受信者を電子メールメッセージに追加するには、 MailAddress 受信者のアドレスのを作成し、そのオブジェクトをプロパティによって返されるコレクションに追加し Bcc ます。To add a BCC recipient to an email message, create a MailAddress for the recipient's address, and then add that object to the collection returned by the Bcc property.

受信者が電子メールメッセージを表示する場合、 Bcc 通常、アドレスは表示されません。When recipients view an email message, the Bcc addresses are usually not displayed.
