Process.BasePriority Eigenschaft

Definition

Ruft die Basispriorität des zugeordneten Prozesses ab.Gets the base priority of the associated process.

public:
 property int BasePriority { int get(); };
public int BasePriority { get; }
member this.BasePriority : int
Public ReadOnly Property BasePriority As Integer

Eigenschaftswert

Int32

Die Basispriorität, die anhand der PriorityClass des zugeordneten Prozesses berechnet wird.The base priority, which is computed from the PriorityClass of the associated process.

Ausnahmen

Der Prozess wurde beendet.The process has exited.

- oder --or-

Der Prozess wurde nicht gestartet, daher gibt es keine Prozess-ID.The process has not started, so there is no process ID.

Beispiele

Im folgenden Beispiel wird eine Instanz von Editor gestartet.The following example starts an instance of Notepad. Im Beispiel werden dann die verschiedenen Eigenschaften des zugeordneten Prozesses abgerufen und angezeigt.The example then retrieves and displays various properties of the associated process. Das Beispiel erkennt, wenn der Prozess beendet wird, und zeigt den Exitcode des Prozesses an.The example detects when the process exits, and displays the process's exit code.

Hinweise

Der von dieser Eigenschaft zurückgegebene Wert stellt die zuletzt aktualisierte Basis Priorität des Prozesses dar.The value returned by this property represents the most recently refreshed base priority of the process. Um die aktuelle Basis Priorität zu erhalten, müssen Sie zuerst die-Methode aufzurufen Refresh() .To get the most up to date base priority, you need to call Refresh() method first.

Die BasePriority des Prozesses ist die Anfangs Priorität für Threads, die innerhalb des zugeordneten Prozesses erstellt werden.The BasePriority of the process is the starting priority for threads created within the associated process. Sie können Informationen über die Basis Priorität mithilfe des Prioritäts Basis Zählers des System Monitors anzeigen.You can view information about the base priority through the System Monitor's Priority Base counter.

Basierend auf der verstrichenen Zeit oder anderen Steigerungen kann das Betriebssystem die Basis Priorität ändern, wenn ein Prozess vor anderen versetzt werden soll.Based on the time elapsed or other boosts, the operating system can change the base priority when a process should be placed ahead of others.

Mit der- BasePriority Eigenschaft können Sie die dem Prozess zugewiesene anfangs Priorität anzeigen.The BasePriority property lets you view the starting priority assigned to a process. Da Sie jedoch schreibgeschützt ist, können Sie nicht verwenden, BasePriority um die Priorität des Prozesses festzulegen.However, because it is read-only, you cannot use the BasePriority to set the priority of the process. Verwenden Sie die-Eigenschaft, um die Priorität zu ändern PriorityClass .To change the priority, use the PriorityClass property. Der BasePriority kann mit dem System Monitor angezeigt werden, während der PriorityClass nicht ist.The BasePriority is viewable using the System Monitor, while the PriorityClass is not. Sowohl BasePriority als auch PriorityClass können Programm gesteuert angezeigt werden.Both the BasePriority and the PriorityClass can be viewed programmatically. In der folgenden Tabelle wird die Beziehung zwischen BasePriority Werten und PriorityClass Werten angezeigt.The following table shows the relationship between BasePriority values and PriorityClass values.
