示例1: WalkControlElements
/// <summary>
/// Walks the UI Automation tree and adds the control type of each element it finds
/// in the control view to a TreeView.
/// </summary>
/// <param name="rootElement">The root of the search on this iteration.</param>
/// <param name="treeNode">The node in the TreeView for this iteration.</param>
/// <remarks>
/// This is a recursive function that maps out the structure of the subtree beginning at the
/// UI Automation element passed in as rootElement on the first call. This could be, for example,
/// an application window.
/// CAUTION: Do not pass in AutomationElement.RootElement. Attempting to map out the entire subtree of
/// the desktop could take a very long time and even lead to a stack overflow.
/// </remarks>
private void WalkControlElements(AutomationElement rootElement, TreeNode treeNode)
{
// Conditions for the basic views of the subtree (content, control, and raw)
// are available as fields of TreeWalker, and one of these is used in the
// following code.
AutomationElement elementNode = TreeWalker.ControlViewWalker.GetFirstChild(rootElement);
