How to encapsulate event type member in c#?

I can create getter and setter for an int member. How to do this if this member is an event type ?

Update: I want to call another method each 开发者_Go百科time this member is set.

You can implement custom event accessors.

Example:

public delegate int DoSomething();
private event DoSomething _somethingHappened;
public event DoSomething SomethingHappened
{
  add { _somethingHappened += value; }
  remove { _somethingHappened -= value; }
}

Events are in fact ready for consumption, put very simply, declaring an event is actually defining a getter/setter for the underlying delegate and it is therefore not necessary to define explicit getter/setter.

If you want to do some kind of custom handling for the attach/detach of handlers to the event then you can take a look at the following MSDN documentation

Events are declared using a delegate type - simply make your property the delegate type.

From MSDN:

In the .NET Framework class library, events are based on the EventHandler delegate and the EventArgs base class.

public EventHandler MyEvent {get; set;}
