Using Logger Filter with Not Equal condition Log4net

Question

Dears

I am using log4net in my c# application i have different logger which insert text lines in my single log file.

But now i wanted to add a new logger which should not post log entries in the same file rather i should log in a different file so i configured a new fileAppender, After doing whatever i found on the net i am able to create a different file for my new logger but it echoes the same value in first log file too.

so please if anybody knows about the use of LogFilters so that i could add "Logger <> New logger " match in previously configured appender.

Assuming you have your "special" logger like this:

ILog logger1 = LogManager.GetLogger("namespace.special_class");

then you can configure log4net as follows:

<logger name="namespace.special_class" additivity="false">
   <appender-ref ref="RollingFileAppender4SpecialMessages" />
</logger>

<root>
   <level value="ALL" />
   <appender-ref ref="StandardRollingFileAppender" />
</root>

This way your special class will use its own file appender. If you need the log messages from this class in your normal log file, then you need to remove the "additivity" attribute.
