Комментарии

Класс NetworkChange вызывает NetworkAddressChanged события при изменении адреса сетевого интерфейса, также называемого сетевым карта или адаптером.

NetworkChange Чтобы объект вызывал метод обработки событий при NetworkAddressChanged возникновении события, необходимо связать метод с делегатом NetworkAddressChangedEventHandler и добавить этот делегат в это событие.
