实现

注解

使用 GroupDescriptions定义组时,视图对象(CollectionViewSource 对象或从 CollectionView派生的对象)将包装 CollectionViewGroup 对象中的每个组。When you define groups using the GroupDescriptions, your view object (a CollectionViewSource object or an object that derives from CollectionView) wraps each group in a CollectionViewGroup object.
