为什么ReadOnlyObservableCollection.CollectionChanged不会公开？ [英] Why is ReadOnlyObservableCollection.CollectionChanged not public?

问题描述

为什么 ReadOnlyObservableCollection.CollectionChanged 受保护且不公开（作为相应的 ObservableCollection.CollectionChanged is）？

使用集合实现 INotifyCollectionChanged如果我无法访问 CollectionChanged 事件

div>

以下是解决方案： ReadOnlyObservableCollection上的CollectionChanged事件

您必须将集合强制转换为 INotifyCollectionChanged / p>

Why is ReadOnlyObservableCollection.CollectionChanged protected and not public (as the corresponding ObservableCollection.CollectionChanged is)?

What is the use of a collection implementing INotifyCollectionChanged if I can't access the CollectionChanged event?

解决方案

Here's the solution: CollectionChanged events on ReadOnlyObservableCollection

You have to cast the collection to INotifyCollectionChanged.
