Log4net 根据日志类别保存到不同的文件，并按照日期生成不同文件名称

<configuration>
    <configSections>
        <!--日志记录-->
        <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
    </configSections>

    <log4net>
        <root></root>
        <logger name="Logger">
            <level value="ALL" />
            <appender-ref ref="ErrorRollingFileAppender" />
            <appender-ref ref="InfoRollingFileAppender" />
        </logger>

            <param name="datePattern" value="yyyy-MM-dd.'Info.txt'" />

            </layout>
            <filter type="log4net.Filter.LevelRangeFilter">

                <param name="LevelMax" value="INFO" />
            </filter>
        </appender>

            </layout>
            <filter type="log4net.Filter.LevelRangeFilter">
                <param name="LevelMin" value="ERROR" />
                <param name="LevelMax" value="ERROR" />
            </filter>
        </appender>
    </log4net>
</configuration>

代码使用记录器：

private static readonly ILog infoLogger = LogManager.GetLogger("Logger");
XmlConfigurator.Configure();
infoLogger.Info(message);
