可观察队列？

是否有人编写了实现 INotifyCollectionChanged 的​​ .Net 通用队列版本，或者是否已经在 .Net 框架深处隐藏了某个版本？

快速搜索没有显示任何结果。但接口很简单，扩展 Queue 类并添加对该接口的支持几乎是微不足道的。只需重写所有方法即可：

// this isn't the best code ever; refactor as desired
protected void OnCollectionChanged( NotifyCollectionChangedEventArgs ccea){
  var temp = CollectionChanged;
  if(temp != null) temp(this, ccea);  
}

// and later in the class

public override SomeMethodThatAltersTheQueue(object something){
  // record state of collection prior to change
  base.SomeMethodThatAltersTheQueue(something)
  // create NotifyCollectionChangedEventArgs with prior state and new state
  OnCollectionChanged(ccea);
}
