	{1}

	", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"), obj.ToString());
	 #endregion

	 sw.WriteLine(value);
	 sw.Flush();
	 }
	 }
	 }
	 }));
	 thread.Start(log);
	 }
	 #endregion

	 #region 写日志

	 {
	 string logPath = ConfigurationManager.AppSettings["LogPath"] + "\\FQDService_Log.txt";
	 WriteFile(log, logPath);
	 }
	 #endregion

	 #region 写错误日志
	 /// <summary>
	 /// 写错误日志
	 /// </summary>
	 public static void WriteErrorLog(string log)
	 {
	 string logPath = ConfigurationManager.AppSettings["LogPath"] + "\\FQDService_ErrorLog.txt";
	 WriteFile(log, logPath);
	 }
	 #endregion

	 }
	}

试试其它关键字

　写文本日志　　写日志　　日志

可能有用的
