Conigure log4net for .net dll


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.

Re: Conigure log4net for .net dll

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

  </configSections>

    <appender name="Class1" type="log4net.Appender.RollingFileAppender">
      <file value="c:\\Log4net.txt" />
      <appenderToFile value="true"></appenderToFile>

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

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.

Re: Conigure log4net for .net dll

Debashish,

The logger named 'ClassLibrary1' references to an appender called 'application' which doesn't exist in the configuration file, this is an invalid reference that will throw and exception internally in the log4net assembly.

You can read debugging output from log4net by adding these key to your application cofiguration file:

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

Also, remember to call XmlConfiguration.Configure()
