Configurable configuration file location

Is there any way to specify the configuration file log4net should use via a
configuration file?  For example, let's say I have three different
applications that all want to use the same log4net configuration.  Is it
possible to set a value in each application's app.config file that log4net
would use as the path to its configuration file?  Or, would it be up to each
application to read such a configuration setting and programmatically
configure log4net?

 

I haven't seen anything in the log4net documentation about this, but thought
I would ask just in case.

 

 

Thanks,

Mike

If you're asking if one of the Configure methods looks for a certain
key in an application's appSettings before looking for the log4net node
in the app.config the answer is no. You'd have to write code to do that
yourself:

 XmlConfigurator.Configure(
  new FileInfo(
   ConfigurationSettings.AppSettings["log4net-config-file"]));

According to these two articles:

 http://www.devx.com/vb2themax/Tip/18880
 http://weblogs.asp.net/pwilson/archive/2003/04/09/5261.aspx

The syntax for including an external appSettings file is:

 <appSettings file="YourSettings.config">
  <add key="KeyToOverride" value="Original" />
  <add key="KeyToNotOverride" value="Standard" />
 </appSettings>

I believe this is possible in .NET 2.0 as it allows for the ability to
"include" configuration files. To do this in 1.x, would be trickier. You
could assemble the configuration file manually, combining the information
from the log4net configuration file. Another solution would be to have the
log4net assembly look specifically for a log4net configuration file instead
of the application's configuration file.
