推荐答案
我不知道的ObservableCollection 的任何图形教程。在的ObservableCollection＆LT; T＆GT; 类是一个集合类型（如列表＆LT; T＆GT; ），这意味着它持有的对象给定类型 T 。是什么让的ObservableCollection 的特殊的是，当一个新的对象被添加或当一个对象被删除，它告诉观察家。这是特别有用的UI的使用WPF实现的，因为esentially，当一个对象被添加或删除一个观察的集合，用户界面将自动更新。这是因为，当绑定到一个观察的集合，WPF会自动添加一个事件处理程序的 ObservableCollecion 的的 CollectionChanged 事件。
I don't know of any graphical tutorial of ObservableCollection. The ObservableCollection<T> class is a collection type (like List<T>) which means that it holds objects of a given type T. What makes ObservableCollection special is that it "tells" observers when a new object is added or when an object is removed. This is especially useful for UI's implemented using WPF, because esentially, when an object is added to or removed from an observable collection, the UI is automatically updated. This happens because, when binding to an observable collection, WPF automatically adds an event handler to the ObservableCollecion's CollectionChanged event.
