NLog简单使用

一、安装

二、安装后会在根目录出现NLog.config配置文件,简单修改配置文件为写入文件记录日志:

<?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="Error" 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.
    -->

    
    <!--Write events to a file with the date in the filename.-->
    <target xsi:type="File" name="f" fileName="${basedir}/logs/${shortdate}.log"
            layout="${longdate} ${uppercase:${level}} ${message}" />
    
  </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"-->
    <logger name="*" minlevel="Debug" writeTo="f" />
  </rules>
</nlog>

 

三、使用方法:

 private static Logger logger = LogManager.GetCurrentClassLogger();

 protected void Application_Error(Object sender, EventArgs e)
        {
            Exception lastError = Server.GetLastError();
            if (lastError != null)
            {
                logger.Error(lastError);
            }
        }
  logger.Info("Application_Start");

 

简单的异常日志写入完成,看了配置项太多头有点大,先这样了
