static void CreateBccTestMessage( String^ server )
{
   MailAddress^ from = gcnew MailAddress( L"ben@contoso.com",L"Ben Miller" );
   MailAddress^ to = gcnew MailAddress( L"jane@contoso.com",L"Jane Clayton" );
   MailMessage^ message = gcnew MailMessage( from,to );
   message->Subject = L"Using the SmtpClient class.";
   message->Body = L"Using this feature, you can send an email message from an application very easily.";
   MailAddress^ bcc = gcnew MailAddress( L"manager1@contoso.com" );
   message->Bcc->Add( bcc );
   SmtpClient^ client = gcnew SmtpClient( server );
   client->Credentials = CredentialCache::DefaultNetworkCredentials;
   Console::WriteLine( L"Sending an email message to {0} and {1}.", to->DisplayName, message->Bcc );
   try
   { 
       client->Send( message );
   }
   catch ( Exception^ ex )
   {
       Console::WriteLine(L"Exception caught in CreateBccTestMessage(): {0}", 
                     ex->ToString() );
   }
   client->~SmtpClient();
}

{
    MailAddress from = new MailAddress("ben@contoso.com", "Ben Miller");
    MailAddress to = new MailAddress("jane@contoso.com", "Jane Clayton");
    MailMessage message = new MailMessage(from, to);
    message.Subject = "Using the SmtpClient class.";
    message.Body = @"Using this feature, you can send an email message from an application very easily.";
    MailAddress bcc = new MailAddress("manager1@contoso.com");
    message.Bcc.Add(bcc);

    client.Credentials = CredentialCache.DefaultNetworkCredentials;
    Console.WriteLine("Sending an email message to {0} and {1}.",
        to.DisplayName, message.Bcc.ToString());

    try
    {
        client.Send(message);
    }
    catch (Exception ex)
    {
        Console.WriteLine("Exception caught in CreateBccTestMessage(): {0}",
            ex.ToString());
    }
}

    Try

注解

若要向电子邮件添加密件抄送收件人，请为收件人的地址创建 MailAddress ，然后将该 对象添加到 由 属性返回的 Bcc 集合中。

当收件人查看电子邮件时， Bcc 通常不会显示地址。
