了解下C#异常时的输出

Sample Code:

            try
            {
                string re = "1.1".Substring(1,4);
            }
            catch (Exception ex)
            {

                logger.ErrorFormat("Exception:\n{0}\n BaseException:\n{1} \n GetType:\n{2} \nMessage:\n{3}\n StackTrace:\n{4}", ex, ex.GetBaseException(), ex.GetType(), ex.Message, ex.StackTrace);
            }
