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

public class LogHelper
{
public static readonly log4net.ILog loginfo = log4net.LogManager.GetLogger("loginfo");

public static readonly log4net.ILog logerror = log4net.LogManager.GetLogger("logerror");

//public static void SetConfig()
//{
// log4net.Config.XmlConfigurator.Configure();
//}

//public static void SetConfig(FileInfo configFile)
//{
// log4net.Config.XmlConfigurator.Configure(configFile);
//}

public static void WriteLog(string info)
{
if (loginfo.IsInfoEnabled)
{
loginfo.Info(info);
}
}

public static void WriteErrorLog(string info)
{
if (logerror.IsErrorEnabled)
{
logerror.Error(info);
}
}
}
