CSoft.LoggerNLog 5.0.4

Log

日志存储

第一步

一般情况，可加参数表示指定文件名

Logs.LogFactory = new NLogFactory();

Android下自动读取Assets下的配置

Logs.LogFactory = new NLogFactory("assets/NLog.config");

第二步

Android下的配置文件，其他的无非给下路径，Android下路径不熟，给个例子，详见文章尾部摘抄

<?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">
	<variable name="myvar" value="myvalue"/>
	<variable name="logDir" value="${specialfolder:folder=MyDocuments}/Logs/"/>
	<targets async="true">
		<target xsi:type="File" name="error" fileName="${logDir}/Error/${shortdate}.log" layout="${level:upperCase=true} ${longdate}  ${logger} ${callsite:skipFrames=2} ${message} ${onexception:${newline} ${exception:format=toString,Data} ${newline} ${stacktrace} ${newline}"/>
		<target xsi:type="File" name="info" fileName="${logDir}/Info/${shortdate}.log" layout="${level:upperCase=true} ${longdate}  ${logger} ${callsite:skipFrames=2} ${message}"/>
		<target xsi:type="File" name="warn" fileName="${logDir}/Warn/${shortdate}.log" layout=" ${level:upperCase=true} ${longdate}  ${logger} ${callsite:skipFrames=2} ${message} ${onexception:${newline} ${exception:format=toString,Data} ${newline} ${stacktrace} ${newline}"/>
		<target xsi:type="File" name="trace" fileName="${logDir}/Trace/${shortdate}.log" layout=" ${longdate} ${message}"/>
		<target xsi:type="File" name="debug" fileName="${logDir}/Debug/${shortdate}.log" layout=" ${longdate} ${message}"/>
	</targets>
	<rules>
		<logger name="*" minlevel="Error" maxlevel="Error" writeTo="error"/>
		<logger name="*" minlevel="Info" maxlevel="Info" writeTo="info"/>
		<logger name="*" minlevel="Warn" maxlevel="Warn" writeTo="warn"/>
		<logger name="*" minlevel="Trace" maxlevel="Trace" writeTo="trace"/>
		<logger name="*" minlevel="Debug" maxlevel="Debug" writeTo="debug"/>
	</rules>
</nlog>

第三步

在使用到的类中加入

//Main是你需要调用的类
private static readonly ILogger _logger = Logs.LogFactory.GetLogger<Main>();

第四步

可在需要位置输出日志,比如：

_logger.Info("hello");
_logger.Error(e.Exception);
