Question

simple question :-

i have the following simple if (..) statements :-

if (foo == Animal.Cat || foo == Animal.Dog)
{ .. }

if (baa == 1|| baa == 69)
{ .. }

is it possible to refactor these into something like …

DISCLAIMER: I know this doesn’t compile .. but this is sorta what i’m trying to get…

if (foo == (Animal.Cat || Animal.Dog))
{ .. }

if (baa == (1 || 69))
{ .. }

Cheers 🙂

EDIT

I wonder if a lambda expression extension could do this? 😛

Answer 1

I usually create an extension method called IsIn() that takes a generic parameter array of type <T> and then calls .Contains() on it, passing the instance on which the extension is called.

It looks like if (foo.IsIn(foo1, foo2)). Very simple to write, super easy to use.
