异常处理 以此警示后人

异常类Exception 

记录成文本日志 

有些人喜欢记录ex.Message 

这样记录一般只有一行中文的错误提示 

结果查原因半天查询不不到 

直接序列化Exception 也会出现一定的问题会报循环引用问题

我们一般向下面这样处理

/// <summary>
        /// 创建异常消息
        /// </summary>
        /// <param name="ex">异常信息</param>
        /// <param name="remark">备注</param>
        /// <returns>结果</returns>
        private static StringBuilder CreateErrorMessage(System.Exception ex, string remark)
        {
            StringBuilder stringBuilder = new StringBuilder();
            stringBuilder.Append("************************Exception Start********************************");
            string newLine = Environment.NewLine;
            System.Exception innerException = ex.InnerException;
            stringBuilder.AppendFormat("Exception Date:{0}{1}", DateTime.Now, Environment.NewLine);
            if (innerException != null)
            {
                stringBuilder.AppendFormat("Inner Exception Type:{0}{1}", innerException.GetType(), newLine);
                stringBuilder.AppendFormat("Inner Exception Message:{0}{1}", innerException.Message, newLine);
                stringBuilder.AppendFormat("Inner Exception Source:{0}{1}", innerException.Source, newLine);
                stringBuilder.AppendFormat("Inner Exception StackTrace:{0}{1}", innerException.StackTrace, newLine);
            }
            stringBuilder.AppendFormat("Exception Type:{0}{1}", ex.GetType(), newLine);
            stringBuilder.AppendFormat("Exception Message:{0}{1}", ex.Message, newLine);
            stringBuilder.AppendFormat("Exception Source:{0}{1}", ex.Source, newLine);
            stringBuilder.AppendFormat("Exception StackTrace:{0}{1}", ex.StackTrace, newLine);
            stringBuilder.AppendFormat("Exception Remark：{0}{1}", remark, newLine);
            stringBuilder.Append("************************Exception End************************************");
            stringBuilder.Append(newLine);
            return stringBuilder;
        }
