在WPF或其他XAML平台上，可以使用AutomationID属性为UI控件提供唯一标识符。当AutomationID属性更改时，可以在代码中使用AutomationProperties.AutomationIdChangedEvent事件来处理此更改。以下是一些示例代码：

    


public partial class MyWindow : Window
{
    public MyWindow()
    {
        InitializeComponent();
        Button myButton = FindByName("MyButton");
        AutomationProperties.SetAutomationId(myButton, "NewButtonId");
        AutomationProperties.GetAutomationId(myButton); // returns "NewButtonId"
    }

    private T FindByName(string name) where T : DependencyObject
    {
        T child = null;
        for (int i = 0; i < VisualTreeHelper.GetChildrenCount(this); i++)
        {
            DependencyObject depObj = VisualTreeHelper.GetChild(this, i);
            if (depObj is T)
            {
                child = depObj as T;
                FrameworkElement frameworkElement = child as FrameworkElement;
                if (frameworkElement?.Name == name)
                {
                    return child;
                }

                child = FindByName(name);
                if (child != null)
                {
                    return child;
                }
            }
        }
        return null;
    }
}
