ContainsAny & EquelsAny

This post is a bit of a reference for myself and also a handy tip for those wondering how to perform Contains and Equels on a collection of strings.

For the purposes I needed I simply wanted to check if a string Equels Any or Contains Any of an array of strings. I put these together as a couple of extension methods:

public static bool ContainsAny(this string input, string[] items)
        {
            return items.Any(input.Contains);
        }

        public static bool EqualsAny(this string input, string[] items)
        {
            return items.Any(input.Equels);
        }

That’s all that’s required.

This means we can now do things like:

bool isWomenOrUnisex = category.EquelsAny(new []{"women","unisex"});

Simples!
