Hi
I am developing a ClassLibrary in C#(VS2008).
I have refernce to log4net.dll.
This DLL has only one function which will log a
string using log4net.
My AssemblyInfo.cs has the following entry:
[assembly: log4net.Config.XmlConfigurator()]
I use this above dll in a WINForms application.

The problem is log4net is not logging any information.

Appreciate help.

Have you verified that your App.Config configures log4net correctly? What happens when you turn on log4net's internal debugging?

hi,

This is what i ahve in app.config,  please correct me if i am wrong.

<configuration>
  <configSections>
    <section name="log4net"
type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  </configSections>
  <log4net>
    <appender name="Class1" type="log4net.Appender.RollingFileAppender">
      <file value="c:\\Log4net.txt" />
      <appenderToFile value="true"></appenderToFile>
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%d [%t] %-5p %c - %m%n" />
      </layout>
    </appender>
    <logger name="ClassLibrary1">
      <level value="DEBUG" />
      <maximumFileSize value="256KB" />

      <appender-ref ref="application" />
    </logger>
    <root>
      <level value="DEBUG">
        <appender-ref ref="Class1"></appender-ref>
      </level>
    </root>
  </log4net>

</configuration>

Thanks

Dude,

You can diagnose this issue by turning on the log4net internal
debugging.  Do this by putting the following into the app.config file
of your Main app:

<configuration>
    <appSettings>
        <add key="log4net.Internal.Debug" value="true"/>
    </appSettings>
</configuration>

Next, you will want to catch the messages that log4net writes.  You
can do this in your app.config file as well.  Put in a section like
this:

<system.diagnostics>
   <trace autoflush="true">
     <listeners>
       <add name="textWriterTraceListener"
            type="System.Diagnostics.TextWriterTraceListener"
            initializeData="C:\temp\log4net_internal.log"/>
     </listeners>
   </trace>
 </system.diagnostics>

This will take the output of log4net and put it into a simple log
file.  Then you should be able to see just what it is that log4net is
getting stuck on.
