log4net within Excel RTD/UDF

Hi,

I am using C# to write an Excel RTD (real-time data) and UDF (user defined 
function) and having trouble figuring out how I can get log4net to 
configure itself.  My understanding is that it uses the 
AppDomain.CurrentDomain.BaseDirectory to look for the configuration file. 
This is the Excel installation directory.  I however do not install my 
application into that directory and do not put any configuration there. My 
code is installed into its' own directory which can be found by using 
Assembly.GetExecutingAssembly().CodeBase within my code.  Is there an easy 
way to have log4net use a different directory when searching for the 
configuration file?

I have had success manually loading the configuration, but this forces me 
to put my loading logic into all of the potential entry points.  I can 
have multiple RTDs and UDFs defined within one assembly.  So I am looking 
for an easy way to have one place to worry about the configuration 
loading.

thanks

Michael

Brian,

Yes, that is what I meant by manually.

I have not looked at log4net code, but I wonder if the attribute can be 
enhanced to use the different base directories.

Thanks for looking.

Michael

Hi Michael,

I believe the easiest way to do that is to to call 
XmlConfigurator.Configure with the FileInfo object for your desired file.
Is that what you meant when you said you were manually loading the 
configuration? 
If so, I apologize but I think that may be the best you can do.
