How do I override the equals operator == for an interface in C#?
The operator == is static. You cannot define static methods for interfaces in C#. Also, for all operators at least one of the argument types needs to be of the same type as the class it is defined in, therefore: No operator overloading for interfaces :
c# - Interfaces — What's the point? - Stack Overflow
But, with the interface, you can place the new change in a new interface and just use that interface where its needed (Interface Seq. from SOLID).

Oct 26, 2009 · Thx for ur help.. it is not that I thought what worked was incorrect, but that my expectation was the the CLR would equate the two generic types.. the one one the Interface and the One on the Method.. i.e. Interface <T>'s T would be the same as T Read<T> 's return type <T> as well as the Read<T>; but in reality, it only matches Interface<T>'s "T" with the return Type
c# - What is the difference between an interface and a class, and …
Oct 2, 2019 · C# doesn't have duck typing - just because you know a certain method is implemented across a set of concrete classes doesn't mean you can treat them all the same with regards to calling that method.

c# - How to represent an Enum in an Interface? - Stack Overflow
Jul 7, 2020 · +1 I created an iEventLogTypes class as helper for my IEventLog interface. Right now it only contains an enum, but I can add any "types" that I need within my interface. I like sticking the enum in a "similar named" class so that the enum is more tightly bound to the specific interface, even if it's in "name only". –
