This is an alternative for "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(new string(s.Select(toggle).ToArray()));
Performance may be not optimal, but probably good enoug for many cases...
