 后台：

            List<T> list=GetList();
            var sourceView = new ListCollectionView(list);
            var groupDesctripition = new PropertyGroupDescription("room_code");//按room_code分组，room_code为集合中的属性
            sourceView.GroupDescriptions.Add(groupDesctripition);
            listview1.ItemsSource = sourceView;
