Custom filename in a rolling Log4Net logfile?

Question

We have a ASP .Net application whereby we use Log4Net to log details within the app - nothing new there - and the rolling log filenames are in the usual format of:

rolling-log.txt 
rolling-log.txt.1
rolling-log.txt.2 etc.

A each user of the application adds to the logfile, the logfile can be difficult to read for a specific user's case and so, we'd like to modify the config file somehow to record the user's log details individually, each writing to a specific file, e.g.

<applicationId>rolling-log.txt
<applicationId>rolling-log.txt.1
<applicationId>rolling-log.txt.2
etc.

where is each user's unique application Id, made up of a five digit number, e.g.

12345rolling-log.txt

Any ideas on the best way to implement this, assuming that it's possible?

Cheers

Answer 1

<file type="log4net.Util.PatternString">
  <conversionPattern value="C:\Logs\log-%date{ yyyy.MM.dd.HH.mm.ss}-[%processid].log" />
</file>

from here

Answer 2

look for log4net Context Properties...

in your code :

log4net.GlobalContext.Properties["id"] = "12345";

then

log4net.Config.XmlConfigurator.ConfigureAndWatch(new FileInfo("configPath"));

in the log4net config file:

<file type="log4net.Util.PatternString"
            value="%property{id}rolling-log.txt" />
