WPF NotifyPropertyChangeds 是否已编组到调度程序？
如果我更新一个在绑定控件的调度程序之外的线程上抛出 NotifyPropertyChanged 的属性，更新会被强制编组到该调度程序吗？
BackgrounWorker.Run() => { blah.Blahness = 2; // notifies property changed on BW, is this marshalled to the dispatcher? }
If I update a property that throws a NotifyPropertyChanged on a thread other than the bound control's dispatcher is the update forcibly marshalled to this dispatcher?
BackgrounWorker.Run() => { blah.Blahness = 2; // notifies property changed on BW, is this marshalled to the dispatcher? }

是的，
PropertyChanged事件会自动编组到 UI 调度程序，因此您无需使用Invoke显式编组它。请注意，它仅适用于标量属性的更改通知（即
PropertyChanged事件）。集合更改通知（INotifyCollectionChanged.CollectionChanged事件）不会以这种方式工作，它们必须在 UI 线程上手动引发。我编写了一个自动执行此操作的类，您可以找到它 此处。Yes, the
PropertyChangedevent is automatically marshalled to the UI dispatcher, so you don't need to useInvoketo marshall it explicitly.Note that it is only true for change notifications on scalar properties (i.e.
PropertyChangedevent). Collection change notifications (INotifyCollectionChanged.CollectionChangedevent) don't work that way, they must be raised on the UI thread manually. I wrote a class that does it automatically, you can find it here.
