Exemples

Dans l’exemple suivant, un élément racine est passé à une fonction qui retourne une collection de AutomationElements qui sont descendants de la racine et qui répondent à un ensemble de conditions de propriété.

/// the specified condition(s).

/// <param name="targetApp">
/// The automation element from which to start searching.

/// <returns>
/// A collection of automation elements satisfying 
/// the specified condition(s).
/// </returns>

private AutomationElementCollection FindAutomationElement(
    AutomationElement targetApp)
{
    if (targetApp == null)
    {
        throw new ArgumentException("Root element cannot be null.");
    }

    PropertyCondition conditionIsReadOnly =
        new PropertyCondition(
        RangeValuePattern.IsReadOnlyProperty, false);

    return targetApp.FindAll(
        TreeScope.Descendants, conditionIsReadOnly);
}
