Атрибуты

Исключения

Вы пытаетесь получить доступ к свойству ExitTime процесса, запущенного на удаленном компьютере.You are trying to access the ExitTime property for a process that is running on a remote computer. Это свойство доступно только для процессов, запущенных на локальном компьютере.This property is available only for processes that are running on the local computer.

Примеры

В следующем примере кода создается процесс, который выводит файл.The following code example creates a process that prints a file. Процесс вызывает Exited событие при его выходе, а обработчик событий отображает ExitTime свойство и другие сведения о процессе.The process raises the Exited event when it exits, and the event handler displays the ExitTime property and other process information.

Комментарии

Если процесс не был завершен, попытка получить ExitTime свойство вызывает исключение.If the process has not terminated, attempting to retrieve the ExitTime property throws an exception. Используйте HasExited перед получением ExitTime свойства, чтобы определить, завершен ли связанный процесс.Use HasExited before getting the ExitTime property to determine whether the associated process has terminated.
