title: Use reflection to get actual value of the property notified by INotifyPropertyChanged?
body: <p>I am working on a project that will use <code>INotifyPropertyChanged</code> to announce property changes to subscriber classes.</p>
  
  <pre><code>void item_PropertyChanged(object sender, PropertyChangedEventArgs e)
      {
          if (e.PropertyName == "Quantity")
  ....
  </code></pre>
  
  <p>It appears to me that when the subscribing class receives the notification, the only available value it can get is the name of the property. Is there a way to get a reference of the actual object that has the property change? Then I can get the new value of this property from the reference. Maybe using reflection?</p>
  
  <p>Would anyone mind writing a code snippet to help me out? Greatly appreciated.</p>
