Примеры

В следующем примере кода показан метод переопределения PartCommunicationInit , который создает экземпляр класса ParametersOutProviderInitEventArgs для определения параметров, которые будут переданы в событии ParametersOutProviderInit . Данный пример кода является частью большего примера, приведенного для интерфейса IParametersOutProvider .
