Beispiele

Im folgenden Beispiel werden verschiedene statische Bedingungen verwendet, z. B ControlViewCondition . zum Abrufen von Elementen.

/// <summary>
/// Examples of using predefined conditions to find elements.
/// </summary>
/// <param name="elementMainWindow">The element for the target window.</param>
public void StaticConditionExamples(AutomationElement elementMainWindow)
{
    if (elementMainWindow == null)
    {
        throw new ArgumentException();
    }

    // Use TrueCondition to retrieve all elements.
    AutomationElementCollection elementCollectionAll = elementMainWindow.FindAll(
        TreeScope.Subtree, Condition.TrueCondition);
    Console.WriteLine("\nAll control types:");
    foreach (AutomationElement autoElement in elementCollectionAll)
    {
        Console.WriteLine(autoElement.Current.Name);
    }

    // Use ContentViewCondition to retrieve all content elements.
    AutomationElementCollection elementCollectionContent = elementMainWindow.FindAll(
        TreeScope.Subtree, Automation.ContentViewCondition);
    Console.WriteLine("\nAll content elements:");
    foreach (AutomationElement autoElement in elementCollectionContent)
    {
        Console.WriteLine(autoElement.Current.Name);
    }

    // Use ControlViewCondition to retrieve all control elements.
    AutomationElementCollection elementCollectionControl = elementMainWindow.FindAll(
        TreeScope.Subtree, Automation.ControlViewCondition);
    Console.WriteLine("\nAll control elements:");
    foreach (AutomationElement autoElement in elementCollectionControl)
    {
        Console.WriteLine(autoElement.Current.Name);
    }
}
