如何以编程方式获取所有控件的ControlTemplates？(UWP)

using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Media;

public static void GetAllControlTemplates(DependencyObject parent)
{
    int childCount = VisualTreeHelper.GetChildrenCount(parent);
    for (int i = 0; i < childCount; i++)
    {
        DependencyObject child = VisualTreeHelper.GetChild(parent, i);
        
        // 判断子元素是否为控件
        if (child is Control)
        {
            Control control = child as Control;
            
            // 获取控件的ControlTemplate
            ControlTemplate controlTemplate = control.Template;
            
            // 在这里可以对ControlTemplate进行操作或获取相关信息
            // ...
        }
        
        // 递归获取子元素的ControlTemplates
        GetAllControlTemplates(child);
    }
}
