  1. Generally, how shall I use the built-in generic delegate EventHandler<TEventArgs> provided by the .NET Framework?

  2. Specifically, I saw an example

    Class MyEvent{
    ...
    public event EventHandler<MyEventArgs> SomeEvent; 
    ...
}

Class EventDemo{

    ...

    void MyEventHandler(Object sender, MyEventArgs e){
        ...
    }

    ...

    myEvent = new MyEvent();

    myEvent.SomeEvent += new EventHandler<MyEventArgs>(MyEventHandler);

}

    Can 

    myEvent.SomeEvent += new EventHandler<MyEventArgs>(MyEventHandler);

    be replaced by

    myEvent.SomeEvent += MyEventHandler;

    In particular, does new EventHandler<MyEventArgs>() try to convert the function MyEventHandler from one type to another type?

Thanks.

  • Your question has nothing to do with the specific delegate type, nor the generic nature of a delegate type. The difference in the syntax is simply that the compiler knows how to infer the instantiation of a delegate instance from a method group name directly. You can omit the new operator and constructor call in _any_ context where a new delegate instance is desired. See marked duplicate for details. – Peter Duniho Feb 08 '17 at 03:22
