如何在Xamarin中获取父控件的所有子控件？

public static List<View> GetAllSubviews(View parentView)
{
    List<View> subviews = new List<View>();

    if (parentView != null && parentView is ViewGroup)
    {
        ViewGroup parentLayout = (ViewGroup)parentView;
        for (int i = 0; i < parentLayout.ChildCount; i++)
        {
            View childView = parentLayout.GetChildAt(i);
            subviews.Add(childView);
            if (childView is ViewGroup)
            {
                subviews.AddRange(GetAllSubviews(childView));
            }
        }
    }

    return subviews;
}

ViewGroup parentView = FindViewById<ViewGroup>(Resource.Id.parentLayout);
List<View> allSubviews = GetAllSubviews(parentView);
