示例1: CachePropertiesWithScope
/// <summary>
/// Gets a list box element and caches the Name property of its children (the list items).
/// </summary>
/// <param name="elementMain">The UI Automation element for the parent window.</param>
void CachePropertiesWithScope(AutomationElement elementMain)
{
AutomationElement elementList;
// Set up the CacheRequest.
CacheRequest cacheRequest = new CacheRequest();
cacheRequest.Add(AutomationElement.NameProperty);
cacheRequest.TreeScope = TreeScope.Element | TreeScope.Children;
// Activate the CacheRequest and get the element. Note that the scope of the CacheRequest
// is in relation to the object being retrieved: the list box and its children are
// cached, not the main window and its children.
using (cacheRequest.Activate())
{
// Load the list element and cache the specified properties for its descendants.
Condition cond = new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.List);
elementList = elementMain.FindFirst(TreeScope.Children, cond);
}
if (elementList == null) return;
// The following illustrates that the children of the list are in the cache.
foreach (AutomationElement listItem in elementList.CachedChildren)
{
Console.WriteLine(listItem.Cached.Name);
}
// The following call raises an exception, because the IsEnabled property was not cached.
/*** Console.WriteLine(listItem.Cached.IsEnabled); ***/
// The following illustrates that because the list box itself was cached, it is now
// available as the CachedParent of each list item.
AutomationElement child = elementList.CachedChildren[0];
Console.WriteLine(child.CachedParent.Cached.Name);
