Beispiele

Im folgenden Codebeispiel wird ein Prozess erstellt, der eine Datei ausgibt. Der Prozess löst das Exited -Ereignis aus, wenn er beendet wird, und der Ereignishandler zeigt die ExitTime -Eigenschaft und andere Prozessinformationen an.

Hinweise

Wenn der Prozess nicht beendet wurde, wird beim Versuch, die ExitTime Eigenschaft abzurufen, eine Ausnahme ausgelöst. Verwenden Sie HasExited vor dem Abrufen der ExitTime -Eigenschaft, um zu bestimmen, ob der zugeordnete Prozess beendet wurde.
