Log4Net简单使用

     1.配置文件添加

<configSections>
???<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
?</configSections>

?<log4net>
???<!--<logger name="logerror">
?????<level value="ERROR" />
?????<appender-ref ref="ErrorAppender" />
???</logger>-->
???<logger name="loginfo">
?????<level value="INFO" />
?????<appender-ref ref="InfoAppender" />
???</logger>
???<!--<appender name="ErrorAppender" type="log4net.Appender.RollingFileAppender">
?????<param name="File" value="Log\\LogError\\" />
?????<param name="AppendToFile" value="true" />
?????<param name="MaxSizeRollBackups" value="100" />
?????<param name="MaxFileSize" value="10240" />
?????<param name="StaticLogFileName" value="false" />
?????<param name="DatePattern" value="yyyyMMdd&quot;.txt&quot;" />
?????<param name="RollingStyle" value="Date" />
?????<layout type="log4net.Layout.PatternLayout">
???????<param name="ConversionPattern" value="%n异常时间：%d %n异常级别：%-5p%n异常内容：%m%n" />
?????</layout>
?????--><!--&lt; &gt; = <> %n = 回车--><!--
???</appender>-->
???<appender name="InfoAppender" type="log4net.Appender.RollingFileAppender">
?????<param name="File" value="LogInfo\\" />
?????<param name="AppendToFile" value="true" />
?????<param name="MaxFileSize" value="10240" />
?????<param name="MaxSizeRollBackups" value="100" />
?????<param name="StaticLogFileName" value="false" />
?????<param name="DatePattern" value="yyyyMMdd&quot;.txt&quot;" />
?????<param name="RollingStyle" value="Date" />
?????<layout type="log4net.Layout.PatternLayout">
???????<param name="ConversionPattern" value="日志时间：%d %n日志级别：%-5p ?%n日志内容：%m%n%n" />
?????</layout>
???</appender>
?</log4net>

2.添加Log4Net引用文件

3.配置[assembly: log4net.Config.XmlConfigurator(ConfigFile = "Web.config", Watch = true)]在 AssemblyInfo 下

4.调用方法写日志

 1 public class LogHelper 2 { 3 public static readonly log4net.ILog loginfo = log4net.LogManager.GetLogger("loginfo"); 4 ?5 public static readonly log4net.ILog logerror = log4net.LogManager.GetLogger("logerror"); 6 ?7 //public static void SetConfig() 8 //{ 9 // log4net.Config.XmlConfigurator.Configure();10 //}11 12 //public static void SetConfig(FileInfo configFile)13 //{14 // log4net.Config.XmlConfigurator.Configure(configFile);15 //}16 17 public static void WriteLog(string info)18 {19 if (loginfo.IsInfoEnabled)20 {21 loginfo.Info(info);22 }23 }24 25 public static void WriteErrorLog(string info)26 {27 if (logerror.IsErrorEnabled)28 {29 logerror.Error(info);30 }31 }32 }
