Handy extension method that parses common boolean expressions
public static class StringExtensions
        private static readonly string[] ValidString = 
                       new[] {"true", "t", "1", "yes", "y"};
        public static bool TryConvertToBoolean(this string input)
                if (input == null) return false;
                // Remove whitespace from string and lowercase
                input = input.Trim().ToLower();
                return ValidString.Contains(input);
                return false;
