Question

I am trying to subclass the FileSystemWatcher to intercept the Created event and delay it until I am able to get a handle on the file. Typical scenario. Am I wrong or there is no way of doing this without introducing my own SafeCreated event? Meaning I don’t see a way to override the OnCreated method that is responsible for raising the Created event. Without overriding it I only have the event itself at my disposal, which is no good because the outside world could simply subscribe to that event as well. What am I missing?

Either I’m missing something or I need to be going down the composition route as opposed to inheritance.

You need to use composition as you can’t override the method. However, getting access to the file isn’t in the feature scope of the FileSystemWacher, it just monitors changes. Take care of the getting the handle in your own code.
