aspnet程序配置log4net

1、添加相對應版本的log4net.dll

2、AssemblyInfo.cs文件最末行添加

[assembly: log4net.Config.XmlConfigurator(ConfigFileExtension = "config", Watch = true)]

3、app.config文件的configuration節點添加

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

<log4net>
    <!-- OFF, FATAL, ERROR, WARN, INFO, DEBUG, ALL -->
    <!-- Set root logger level to ERROR and its appenders -->
    <root>
      <level value="ERROR" />
      <appender-ref ref="nhAppender" />
    </root>
    <!-- Print only messages of level DEBUG or above in the packages -->
    <logger name="SysLogger" additivity="false">
      <level value="ALL" />
      <appender-ref ref="SysAppender" />
    </logger>
    <appender name="nhAppender" type="log4net.Appender.RollingFileAppender,log4net">
      <filter type="log4net.Filter.LevelRangeFilter">
        <param name="LevelMin" value="INFO" />
        <param name="LevelMax" value="ERROR" />
      </filter>
      <param name="File" value="nhLogs/" />
      <param name="AppendToFile" value="true" />
      <param name="RollingStyle" value="Date" />
      <param name="DatePattern" value="&quot;Logs_&quot;yyyyMMdd&quot;.txt&quot;" />
      <param name="StaticLogFileName" value="false" />
      <layout type="log4net.Layout.PatternLayout,log4net">
        <!--<param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" />-->
        <param name="ConversionPattern" value="%newline%date [%thread] %n級別：  %-5level %n所在類：%location%n描述：%message%newline %n" />
      </layout>
    </appender>
    <appender name="SysAppender" type="log4net.Appender.RollingFileAppender,log4net">
      <filter type="log4net.Filter.LevelRangeFilter">
        <param name="LevelMin" value="INFO" />
        <param name="LevelMax" value="ERROR" />
      </filter>
      <param name="File" value="Logs/" />
      <param name="AppendToFile" value="true" />
      <param name="RollingStyle" value="Date" />
      <param name="DatePattern" value="&quot;Logs_&quot;yyyyMMdd&quot;.txt&quot;" />
      <param name="StaticLogFileName" value="false" />
      <layout type="log4net.Layout.PatternLayout,log4net">
        <!--<param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" />-->
        <param name="ConversionPattern" value="%newline%date [%thread] %n級別：  %-5level %n所在類：%location%n描述：%message%newline %n" />
      </layout>
    </appender>
  </log4net>

4、在要添加日誌的代碼頁增加log4net類及調用方法：

private static log4net.ILog log = log4net.LogManager.GetLogger("SysLogger");

log.Info("this is a test service start");
