delegete event difference

First,both delegate and event act as function pointer, means you can attach any method of same signature to a delegate. 

Now, what a delegate exactly is?

A delegate as the name suggest and this is the only reason, it is named as delegate is that a delegate can carry messages from one class to another, and he can give the message to any method of another class if the signature of the method matches with his signature.

Like an american delegate give message to an indian , if the indian person is an authorized one to listen to the message whatever the american delegate has to deliver.

 

Now, the the indian person (subscriber) can change the message, means the original message carried by the  amrican delegate (Publisher) can be changed by the indian one, This is pure delegate.

When the indian person (subscribe) can't change the message and can only subscribe to it, we call it event.

so event represents a publisher-subscriber model. You can only watch what the TV publisher showing to you, you can just subscribe or unsubscribe, you can't change it.

 

I think you know how to write  c# code of event and delegate. so, i ommited that.
