Why interfaces in C# don't have a GUID ?

Question

Hi,

Interfaces in Delphi have GUIDs ?

e.g.

type

ISingletonF = interface ['{5182E010-121F-4CD9-85EB-4F31D34354F2}']

procedure Log(logTarget: TListBox; const msg: string);

end;

Why interfaces in C# don't have interfaces ?

Also, are interfaces in C# reference counted ?

TIA

Answer 1

Interfaces in C# are built into the language and have a unique name, so a guid is not required. If c# exposes a com interface, then there is a guid.

in c# an interface is abstract type, meaning you can not create an instance of one. A concrete class must implement an interface and a class instance can be cast to any interface it implements.

c# uses a mark and sweep garbage collector instead of reference counts.
