Question

In a lot of situations we have to do something like this:

if (someVariable == value1 || someVariable == value2 || someVariable == value1...)

Would it be nice if we can do this in following manner:

if (someVariable in {value1, value2, value3...}

We can do this

int[] arr = {value1, value2, value3....};
if (arr.Contains(someVariable)) ...

But its still overwhelming, to my opinion. Why there isn’t a support for this syntax, or there is but I don’t know about it?

Answer 1

I think this may be about as concise as you may get:

if (new int[] { 1, 2, 3 }.Contains(2))
{
    Console.WriteLine("bleh");
}
