log4net 入门教程
1、下载dll
下载地址：http://mirror.reverse.net/pub/apache/logging/log4net/binaries/
github:https://github.com/apache/logging-log4net
2、添加引用
添加log4net.dll的引用（bin\net\2.0\release 不能引用debug版本 不一定是2.0，找对应的net版本）
3、修改配置文件
在web.Config(或app.Config)添加配置，见下文
配置分两步：
1.
<------放到<configuration>字节下的<configSections>字节下--------->
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
2.
<!--log4net配置-->
<------放到<configuration>字节下--------->
<log4net>
<!-- OFF, FATAL, ERROR, WARN, INFO, DEBUG, ALL -->
<!-- Set root logger level to ERROR and its appenders -->
<root>
<level value="WARN"/>
<appender-ref ref="SysAppender"/>
</root> <!-- Print only messages of level DEBUG or above in the packages -->
<logger name="WebLogger">
<level value="DEBUG"/>
</logger> <appender name="SysAppender" type="log4net.Appender.RollingFileAppender,log4net" >
<param name="File" value="App_Data/" />
<param name="AppendToFile" value="true" />
<param name="RollingStyle" value="Date" />
<param name="DatePattern" value=""Logs_"yyyyMMdd".txt"" />
<!-- <ConversionPattern value="记录时间：%date 线程ID:[%thread] 日志级别：%-5level 出错类：%logger property:[%property{NDC}] - 错误描述：%message%newline" />-->
<param name="StaticLogFileName" value="false" />
<layout type="log4net.Layout.PatternLayout,log4net">
<param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" />
<param name="Header" value=" ----------------------header-------------------------- " />
<param name="Footer" value=" ----------------------footer-------------------------- " />
</layout>
</appender>
<appender name="consoleApp" type="log4net.Appender.ConsoleAppender,log4net">
<layout type="log4net.Layout.PatternLayout,log4net">
<param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" />
</layout>
</appender>
</log4net> <!--log4net配置结束-->
4、初始化：
在程序最开始加入log4net.Config.XmlConfigurator.Configure();不要加入页面的load
5、调用：
ILog logger = LogManager.GetLogger("errorMsg");
logger.Error(errorMsg);//将异常信息写到磁盘上.
实例代码：
web.Config
<?xml version="1.0" encoding="utf-8"?>
