How to Toggle String Case in .NET

I couldn't resist to give a Linq/delegate alterantive to the original tip.

How about this:

    public class Program
    {
        public static void Main()
        {
            string s = "AbCdEfGhI§$%&/()1234567890";
            Func<char, char> toggle = c => char.IsUpper(c) ? char.ToLower(c) : char.ToUpper(c);
            Console.WriteLine(s);
            Console.WriteLine(new string(s.Select(toggle).ToArray()));
        }
    }

Cheers
