needs overload operator< and null check

Question

I´m overloading the lessthan-operator in c# and I`m wondering whether this needs to check for null. Below you can find an Example:

public static bool operat         


        

Answer 1

A custom operator is little more than a static method. Moreover, operators in generals shouldn't normally throw exceptions. Which means you need those null-checks if MyClass is a reference-type.

By the way, it's conventional for nulls to be less than non-nulls, which makes your proposed implementation idiomatic.
