Esempio

Nell'esempio di codice seguente viene avviata un'istanza dell'applicazione Blocco note. Nell'esempio vengono quindi recuperate e visualizzate varie proprietà del processo associato. L'esempio rileva quando il processo viene chiuso e visualizza il codice di uscita e le statistiche di picco della memoria.

Commenti

Il valore restituito da questo valore della proprietà rappresenta le dimensioni correnti della memoria di sistema pageable utilizzata dal processo, in byte. La memoria di sistema è la memoria fisica usata dal sistema operativo ed è suddivisa in pool di paging e non di paging. Quando la memoria impaginabile non è in uso, può essere trasferita al file di paging della memoria virtuale su disco. Per ottenere le dimensioni della memoria dell'applicazione usata dal processo, utilizzare la PagedMemorySize64 proprietà .

Questa proprietà può essere usata per monitorare l'utilizzo della memoria nei computer con processori a 32 bit o processori a 64 bit. Il valore della proprietà equivale al contatore delle prestazioni Pool Paged Bytes per il processo.
