public class BaseException<T> : Exception where T : class
        {
            public BaseException() : base() { }

            public BaseException(string message) : base(message) { }

        }

        public class NameNullOrEmptyException 
        {
        }

so i am thinking something like that 

throw new BaseException<NameNullOrEmptyException > but the problem with that the thrown exception is BaseException<NameNullOrEmptyException> and I would like to have it NameNullOrEmptyException
