Step01. 到「管理Nuget套件」安裝 Nlog 及 NLog.Config
Step02. 修改 NLog.config
<?xml version="1.0" encoding="utf-8" ?> <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd" autoReload="true" throwExceptions="false" internalLogLevel="Off" internalLogFile="c:\temp\nlog-internal.log"> <!-- optional, add some variables https://github.com/nlog/NLog/wiki/Configuration-file#variables --> <variable name="myvar" value="myvalue"/> <!-- See https://github.com/nlog/nlog/wiki/Configuration-file for information on customizing logging rules and outputs. --> <targets> <!-- add your targets here See https://github.com/nlog/NLog/wiki/Targets for possible targets. See https://github.com/nlog/NLog/wiki/Layout-Renderers for the possible layout renderers. --> <!--log檔要儲存的路徑--> <target xsi:type="File" name="f" fileName="${basedir}/App_Data/Logs/${shortdate}/${logger}.txt" layout="${longdate} ${uppercase:${level}} ${message}" /> <!-- Write events to a file with the date in the filename. --> </targets> <rules> <!-- add your logging rules here --> <!-- Write all events with minimal level of Debug (So Debug, Info, Warn, Error and Fatal, but not Trace) to "f" --> <!--以檔案形式儲存--> <logger name="*" minlevel="Debug" writeTo="f" /> </rules> </nlog>
Step03. 將NLog 加入程式中
public class HomeController : Controller { private NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger(); public ActionResult Index() { logger.Trace("**** Trace *** "); logger.Debug("**** Debug ***"); logger.Info("**** Info ***"); logger.Warn("**** Warn ***"); logger.Error("**** Error ***"); logger.Fatal("**** Fatal ***"); return View(); } }
Step04. 執行程式,檢查是否有寫入
了解!
Kevin 這個是可以存在雲端的嗎?
