Комментарии

Этот класс инкапсулирует данные для сетевых интерфейсов, также называемых адаптерами, на локальном компьютере. Экземпляры этого класса не создаются; GetAllNetworkInterfaces Метод возвращает массив, содержащий один экземпляр этого класса для каждого сетевого интерфейса на локальном компьютере.
