Is it possible define an extension operator method?

Question

is it possible to define an extension method that at the same time is an operator? I want for a fixed class add the possibility to use a known operator that actually can\'t

Answer 1

The string class is sealed in C#, so creating a string-derived class actually isn't possible.

That being said, an extension method will of course work just fine (as will a standard static method in a helper class) but it won't be an operator, just ordinarily-named method.
