I quite like your DynamicComparer but I have run into a snag with it that I really can’t work out how to fix.
If your _selector evals to null in GetHashCode() it will throw an exception.
eg
var spam = new string[3] { “a”, “b”, null };
var results = spam.Distinct( c => c );

This will crash.

@Omer

Thanks for the LINQ link (ha). I’ll check out that CodePlex project, looks interesting.

Hey Jimmy,

I’ve actually written about these exact things at my blog recently.
You should take a look and you might find something to your liking:

@Nextender, @Philip

Yeah, thanks for the heads-up on the Any method. Don’t need the Contains, although the Any method could have named a little better.

Yeah I was gonna suggest values.Any() too, but it’s been suggested to death. Nobody else touched on the fact that your extensions won’t play nice with other LINQ flavors, particularly LINQ to SQL, which may or may not be a problem.

values.Any(person => person.LastName == “Smith”)

You can skip the Where() and put the lambda directly in the Any().

Why not

values
.Where(person => person.LastName == “Smith”)
.Any()
?
