项目可能会用到的辅助方法

写日志的方法：

 public static void WriteLog(Exception e)
        {
            try
            {
                var fileName = DateTime.Now.ToString("HH:mm:ss").Replace(' ', '_').Replace(':','_');
                var physicalPath = "E:/本机demo/ConsoleApp2/log/"+DateTime.Now.ToString("yyyy-MM-dd")+"/Exceptionlog_" + fileName + ".log";
                if (!File.Exists(physicalPath))
                {
                    var fcreat = File.Create(physicalPath);
                    fcreat.Close();
                }
                using (FileStream aFile = new FileStream(physicalPath, FileMode.Open))
                {
                    StreamReader sr = new StreamReader(aFile, Encoding.GetEncoding("GB2312"));
                    var content = sr.ReadToEndAsync().Result;
                    #region 写入异常信息
                    using (StreamWriter sw = new StreamWriter(aFile, Encoding.UTF8))
                    {
                        sw.Write(content + "\r\n" + DateTime.Now.ToString() + "：\r\n" + e.Message.ToString());  //这里是写入的内容
                        sw.Flush();
                        sw.Close();
                    }
                    #endregion
                    sr.Close();
                }
                    
                
            }
            catch (Exception ex)
            {
                throw (ex);
            }

        }
