Logical Pairs
It is quite common to overload the
equals operator
(==) to test whether two objects are equal
(however equality might be defined for your object). C# insists that
if you overload the equals operator, you must also overload the
not-equals operator (!=
). Similarly, the less than
(<)
and
greater than
(>) operators must be paired, as must the less
than or equals (<=
) and greater than or equals
(>=
) operators.
