Events in an interface

One simple question, if an event is declared like a field of delegate type, except that the keyword event precedes the event declaration how can an interface contain a type declaration? Jayant D. Kulkarni

It can't. An interface can only contain signatures of the following members: Methods, Properties, Indexers and Events. (interface (C# Reference)[^]

But I can not have delegate void MyDelegate(); but I can have event MyDelegate MyEvent; I am asking @ this scenario.
And you have (more or less) already answered yourself. The first is simply not possible, since an interface can only contain signatures of the following members: Methods, Properties, Indexers and Events; and this
delegate void MyDelegate();declares a type that references a method.
