public:
 PropertyCondition(System::Windows::Automation::AutomationProperty ^ property, System::Object ^ value);
public PropertyCondition (System.Windows.Automation.AutomationProperty property, object value);
new System.Windows.Automation.PropertyCondition : System.Windows.Automation.AutomationProperty * obj -> System.Windows.Automation.PropertyCondition
Public Sub New (property As AutomationProperty, value As Object)

Parametri

property
AutomationProperty

Proprietà da testare.

value
Object

Valore per il quale testare la proprietà.

Esempio

Nell'esempio seguente, un PropertyCondition specifica che l'elemento Automazione interfaccia utente da trovare ha un tipo di controllo di List. Viene PropertyCondition quindi usato per ottenere l'elemento list da una casella combinata.

Condition propCondition1 = new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.List);
AutomationElement listElement = elementCombo.FindFirst(TreeScope.Children, propCondition1);

Dim propCondition1 As New PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.List)
Dim listElement As AutomationElement = elementCombo.FindFirst(TreeScope.Children, propCondition1)

Commenti

Il parametro property non può essere BoundingRectangleProperty.

Esempio

Nell'esempio seguente viene usato un oggetto PropertyCondition per recuperare l'elemento Microsoft Automazione interfaccia utente che rappresenta la forma principale di un'applicazione. Il modulo si trova in base a una ricerca senza distinzione tra maiuscole e minuscole per l'identificatore stringa.
