Question

For C# in VS2005, can you do something like this:

if number in [1,2..10,12] { ... }

which would check if number is contained in the set defined in the square brackets?

Answer 1

You can “kind of” do what you want using the Enumerable.Range method:

if (Enumerable.Range(2, 8).Concat(new [] { 1, 12 }).Contains(number)) {
    ....
}

Of course, that’s not nearly as readable as what you find in a basic functional language…
