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

        var tasks = new List { "STOP", "END", "NO", "YES" };
        tasks.Contains(input.Text.ToUpper());

looks better

        var tasks = new List { "stop", "end", "no", "yes" };
        tasks.Exists(x => string.Equals(x, input.Text, StringComparison.OrdinalIgnoreCase));
