Cloning an Exception (kinda sorta)

[Serializable]
        public class MyException : Exception
        {
            public MyException() { }
            public MyException(string message) : base(message) { }
            public MyException(string message, Exception inner) : base(message, inner) { }
            protected MyException(
              System.Runtime.Serialization.SerializationInfo info,
              System.Runtime.Serialization.StreamingContext context)
                : base(info, context) { }
        }
