C # - How to determine if a property is changing

Question

I need to know if the public property (which has getter and setter) has been changed. The property is in a simple class (without a user control / component, etc.).
Is there an elegant way to subscribe to some event that notifies when a property changes?
I tried to understand what microsoft is doing in the Binding object (using a reflector), and this made me learn the PropertyDescriptor.AddValueChanged method, but that did not work for me. maybe it only works for components / user controls ...

Any suggestions?

Thanks,

Answer 1

Just implement the INotifyPropertyChanged interface:
http://msdn.microsoft.com/en-us/library/system.componentmodel.inotifypropertychanged.aspx

This is a fairly well-known interface used by middleware APIs. Just follow the implementation example on this msdn page.

INotifyPropertyChanged should work, but you can also just create your own event specific to this property, without dragging it to system.componentmodel.
