Некоторые сведения относятся к предварительной версии продукта, в которую до выпуска могут быть внесены существенные изменения. Майкрософт не предоставляет никаких гарантий, явных или подразумеваемых, относительно приведенных здесь сведений.
Предоставляет данные для события Elapsed.

- Наследование
Примеры
В следующем примере создается экземпляр объекта Timer, который запускает событие Timer.Elapsed каждые две секунды (2000 миллисекунд), настраивает обработчик событий для события и запускает таймер. Обработчик событий отображает значение свойства ElapsedEventArgs.SignalTime при каждом вызове.
