if statements matching multiple values

Question

Any easier way to write this if statement?

if (value==1 || value==2)

For example... in SQL you can say where value in (1,2) instead of where value=1 or value=2.

I'm looking for something that would work with any basic type... string, int, etc.

How about:

if (new[] {1, 2}.Contains(value))

It's a hack though :)

Or if you don't mind creating your own extension method, you can create the following:

public static bool In<T>(this T obj, params T[] args)
{
    return args.Contains(obj);
}

And you can use it like this:

if (1.In(1, 2))
