这里主要介绍web项目中的用法
1.修改AssemblyInfo.cs文件(Properties文件夹下面)
加入以下代码
[assembly: log4net.Config.DOMConfigurator(ConfigFile = "web.config", Watch = true)]
2.新建log.txt文件(放在根目录下面)
3.修改web.config文件,添加以下代码
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
</configSections>
<log4net>
<root>
<level value="ALL" />
<appender-ref ref="rollingFile" />
</root>
<appender name="rollingFile" type="log4net.Appender.RollingFileAppender,log4net" >
<param name="File" value="log.txt" />
<param name="AppendToFile" value="false" />
<param name="RollingStyle" value="Date" />
<param name="DatePattern" value="yyyy.MM.dd" />
<param name="StaticLogFileName" value="true" />
<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>
<logger name="Log4NetTest.LogTest">
<level value="DEBUG" />
<appender-ref ref="rollingFile" />
<appender-ref ref="coloredConsoleApp" />
<appender-ref ref="SystemEvent" />
</logger>
</log4net>
4.运行代码
using System.IO;
using log4net;
using log4net.Config;
ILog log = LogManager.GetLogger("LogTest");
log.Info("This is a test!");
