What is the difference between delegate and events?

ć Actually events use delegates in bottom. But they add an extra layer on the
delegates, thus forming the publisher and subscriber model.
ć As delegates are function to pointers they can move across any clients. So any
of the clients can add or remove events, which can be pretty confusing. But
events give the extra protection by adding the layer and making it a publisher
and subscriber model.
Just imagine one of your clients doing this
c.XyzCallback = null
This will reset all your delegates to nothing and you have to keep searching where the
error is.
