Si sta provando ad accedere alla proprietà ExitTime per un processo in esecuzione in un computer remoto.You are trying to access the ExitTime property for a process that is running on a remote computer. Questa proprietà è disponibile solo per i processi in esecuzione nel computer locale.This property is available only for processes that are running on the local computer.

Esempi

Esempio di codice seguente crea un processo che consente di stampare un file.The following code example creates a process that prints a file. Il processo genera il Exited evento alla chiusura e il gestore eventi visualizza la ExitTime proprietà e altri elaborare le informazioni.The process raises the Exited event when it exits, and the event handler displays the ExitTime property and other process information.

Commenti

Se non è stato terminato il processo, il tentativo di recuperare il ExitTime proprietà genera un'eccezione.If the process has not terminated, attempting to retrieve the ExitTime property throws an exception. Uso HasExited prima di ottenere il ExitTime proprietà per determinare se è stato terminato il processo associato.Use HasExited before getting the ExitTime property to determine whether the associated process has terminated.
