How can I compare multiple variables to a single condition?

Question

I have this:

if (input.Text.ToUpper() == \"STOP\")

But there are so many possible values that I wouldn\'t be able to specify them all sepa

Answer 1

create extension:

public static class Extension
{
    public static bool EqualsAny(this string item, params string[] array)
    {
        return array.Any(s => item.ToUpper() == s.ToUpper());
    }
}

using:

if (inputText.EqualsAny("STOP", "END", "NO", "YES"))
