Примеры

В следующем примере кода показано использование SessionChangeDescription класс в реализации OnSessionChange метод в класс, производный от ServiceBase.The following code example shows the use of the SessionChangeDescription class in an implementation of the OnSessionChange method in a class derived from ServiceBase. Данный пример кода является частью большего примера для ServiceBase класса.This code example is part of a larger example provided for the ServiceBase class.
