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