Voorbeelden

In het volgende voorbeeld wordt een exemplaar van Kladblok gestart. In het voorbeeld worden vervolgens verschillende eigenschappen van het bijbehorende proces opgehaald en weergegeven. In het voorbeeld wordt gedetecteerd wanneer het proces wordt afgesloten en wordt de afsluitcode van het proces weergegeven.

Opmerkingen

De waarde die door deze eigenschap wordt geretourneerd, vertegenwoordigt de meest recent vernieuwde basisprioriteit van het proces. Als u de meest recente basisprioriteit wilt ophalen, moet u eerst de methode aanroepen Refresh() .

Het BasePriority proces is de beginprioriteit voor threads die zijn gemaakt binnen het bijbehorende proces. U kunt informatie over de basisprioriteit bekijken via de teller Priority Base van systeemmonitor.

Op basis van de tijd die is verstreken of andere boosts, kan het besturingssysteem de basisprioriteit wijzigen wanneer een proces voor anderen moet worden geplaatst.

Met BasePriority de eigenschap kunt u de beginprioriteit bekijken die aan een proces is toegewezen. Omdat het echter alleen-lezen is, kunt u de BasePriority prioriteit van het proces niet instellen. Als u de prioriteit wilt wijzigen, gebruikt u de PriorityClass eigenschap. Het BasePriority is zichtbaar met behulp van de systeemmonitor, terwijl dat PriorityClass niet het is. Zowel de BasePriority als de PriorityClass kan programmatisch worden bekeken. In de volgende tabel ziet u de relatie tussen BasePriority waarden en PriorityClass waarden.
