对于TreeView绑定一直没弄清楚，求师傅指点！

现在有这样一个List

List<PropertyNodeItem> parent = new List<PropertyNodeItem>();
  List<PropertyNodeItem> I = new List<PropertyNodeItem>();
            I.Add(new PropertyNodeItem() { Title = "1", Img = ChangeBitmapToImageSource((Bitmap)Bitmap.FromFile(@"G:\Images\轻量级\1.jpg ")) });
            I.Add(new PropertyNodeItem() { Title = "2", Img = ChangeBitmapToImageSource((Bitmap)Bitmap.FromFile(@"G:\Images\轻量级\2.jpg ")) });
            I.Add(new PropertyNodeItem() { Title = "3", Img = ChangeBitmapToImageSource((Bitmap)Bitmap.FromFile(@"G:\Images\轻量级\3.jpg ")) });
            I.Add(new PropertyNodeItem() { Title = "4", Img = ChangeBitmapToImageSource((Bitmap)Bitmap.FromFile(@"G:\Images\轻量级\4.jpg ")) });
            I.Add(new PropertyNodeItem() { Title = "5", Img = ChangeBitmapToImageSource((Bitmap)Bitmap.FromFile(@"G:\Images\轻量级\5.jpg ")) });
            I.Add(new PropertyNodeItem() { Title = "6", Img = ChangeBitmapToImageSource((Bitmap)Bitmap.FromFile(@"G:\Images\轻量级\6.jpg ")) });
            I.Add(new PropertyNodeItem() { Title = "7", Img = ChangeBitmapToImageSource((Bitmap)Bitmap.FromFile(@"G:\Images\轻量级\7.jpg ")) });
            I.Add(new PropertyNodeItem() { Title = "8", Img = ChangeBitmapToImageSource((Bitmap)Bitmap.FromFile(@"G:\Images\轻量级\8.jpg ")) });
parent.Add(new PropertyNodeItem() { Title = "Parent", Item = I });
