The following code example demonstrates calling this constructor.
static void CreateTimeoutTestMessage( String^ server ) { String^ to = L"jane@contoso.com"; String^ from = L"ben@contoso.com"; String^ subject = L"Using the new SMTP client."; String^ body = L"Using this new feature, you can send an e-mail message from an application very easily."; MailMessage^ message = gcnew MailMessage( from,to,subject,body ); SmtpClient^ client = gcnew SmtpClient( server ); Console::WriteLine( L"Changing time out from {0} to 100.", client->Timeout ); client->Timeout = 100; // Credentials are necessary if the server requires the client // to authenticate before it will send e-mail on the client's behalf. client->Credentials = CredentialCache::DefaultNetworkCredentials; client->Send( message ); }
