Beispiele

Das folgende Beispiel zeigt, wie Sie verwendenAndCondition, um Benutzeroberflächenautomatisierung Elemente zu finden, die einer komplexen Bedingung entsprechen.

/// <summary>
/// Uses AndCondition to retrieve elements that match both of two conditions.
/// </summary>
/// <param name="elementMainWindow">An application window element.</param>
public void AndConditionExample(AutomationElement elementMainWindow)
{
    if (elementMainWindow == null)
    {
        throw new ArgumentException();
    }

    AndCondition conditionEnabledButtons = new AndCondition(
        new PropertyCondition(AutomationElement.IsEnabledProperty, true),
        new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Button));
    AutomationElementCollection enabledButtons = elementMainWindow.FindAll(
        TreeScope.Subtree, conditionEnabledButtons);
    Console.WriteLine("\nEnabled buttons:");
    foreach (AutomationElement autoElement in enabledButtons)
    {
        Console.WriteLine(autoElement.Current.Name);
    }

    // Example of getting the conditions from the AndCondition.
    Condition[] conditions = conditionEnabledButtons.GetConditions();
    Console.WriteLine("AndCondition has " + conditions.GetLength(0) + " subconditions.");
}
