Мы закончили написание программы в главный класс Form1 (для формы Form1 с пользовательским интерфейсом игры). В этом проекте движок игры (Engine Game) находится не в файле Form1.cs (как обычно бывает), а в следующем файле CardEngine.cs.

Теперь в наш проект добавляем новые файлы (для программирования соответствующих игровых действий) по следующей схеме.

В панели Solution Explorer выполняем правый щелчок по имени проекта и в контекстном меню выбираем Add, New Item. В панели Add New Item выделяем шаблон Code File, в окне Name записываем имя нового файла с расширением *.cs и щёлкаем кнопку Add. В проект (и в панель Solution Explorer) добавляется этот файл, открывается пустое окно редактирования кода, в которое записываем следующий код.

Листинг 1.11. Новый файл CardEngine.cs.
