Question

just to throw some code out there

string answer = "hotel"
if (answer == "house"|| answer == "hotel" || answer =="appartment")
{
    DoSomething()
}

I was wondering if there was some way to shorten it to

string answer = "hotel"
if (answer == "house"|| "hotel" || "appartment")
{
    DoSomething()
}

I am aware of the switch statement

switch (answer)
{
    case "house":
    case "hotel":
    case "appartment": DoSomething();
        break;
    default :DoNothing();
}

I am just wondering if there is some syntax sugar like what I described above.

Answer 1

It is possible to use some syntactic sugar for this:

if((new[]{"house", "hotel", "apartment"}).Contains(answer))
{
}

Note that this will create a new array on the fly, so will potentially be more expensive than just the Boolean checks.
