c# - Log4Net error : “Failed to find configuration section log4net” AdoNetAppender -

i made new project testing. trying use log4net write db. getting error.i think in config missing.

log4net:error failed find configuration section 'log4net' in application's .config file. check .config file <log4net> , <configsections> elements. configuration section should like: <section name="log4net" type="log4net.config.log4netconfigurationsectionhandler,log4net" />

form1.cs

    private static readonly log4net.ilog log = log4net.logmanager.getlogger (system.reflection.methodbase.getcurrentmethod().declaringtype);     private void simplebutton1_click(object sender, eventargs e)     {         log4net.config.xmlconfigurator.configure();         log.info("info logging");         log.debug("dadasdasd");     } 

your log4net conf should following should not put on top of log4net node since configuration in independent file:

<log4net>     <!-- level 1 -->     <appender name="adonetappender" type="log4net.appender.adonetappender">       <buffersize value="1" />       <connectiontype value="system.data.sqlclient.sqlconnection, system.data, version=2.0.0.0, culture=neutral, publickeytoken=b77a5c561934e089" />       <connectionstring value="data source=xxx;initial catalog=xxx; integrated security=true;"/>       <commandtext value="insert dbo.log ([date],[thread],[level],[logger],[message],[exception]) values (@log_date, @thread, @log_level, @logger, @message, @exception)" />       <parameter>         <parametername value="@log_date"/>         <dbtype value="datetime"/>         <layout type="log4net.layout.rawtimestamplayout"/>       </parameter>       <parameter>         <parametername value="@thread"/>         <dbtype value="string"/>         <size value="255"/>         <layout type="log4net.layout.patternlayout">           <conversionpattern value="%thread"/>         </layout>       </parameter>       <parameter>         <parametername value="@log_level"/>         <dbtype value="string"/>         <size value="50"/>         <layout type="log4net.layout.patternlayout">           <conversionpattern value="%level"/>         </layout>       </parameter>       <parameter>         <parametername value="@logger"/>         <dbtype value="string"/>         <size value="255"/>         <layout type="log4net.layout.patternlayout">           <conversionpattern value="%logger"/>         </layout>       </parameter>       <parameter>         <parametername value="@message"/>         <dbtype value="string"/>         <size value="4000"/>         <layout type="log4net.layout.patternlayout">           <conversionpattern value="%message"/>         </layout>       </parameter>       <parameter>         <parametername value="@exception"/>         <dbtype value="string"/>         <size value="2000"/>         <layout type="log4net.layout.exceptionlayout"/>       </parameter>     </appender>     <root>       <level value="all"/>       <appender-ref ref="adonetappender"/>     </root>     <logger>       <!-- level 2 -->       <level />       <!-- level 3 -->       <appender-ref />       <!-- level 3 -->     </logger>   </log4net> 

if still facing problems try load conf following:

xmlconfigurator.configure(new fileinfo("path\logging.config")
