log4net：如何关闭程序集引用的日志记录？

Question

In my project I use log4net for logging. My project has a reference to a DLL, which also uses log4net for logging. Now I am facing the problem, that my logfile has both outputs: The messages from my own code and also the messages from the reference.

How can I turn off logging for the referenced DLL?

Answer 1

Alternatively to Ash Burlaczenko's answer, you could also filter those messages from the foreign namespace, like so:

<filter type="log4net.Filter.LoggerMatchFilter">
  <!-- allows this sub-namespace to be logged... -->
  <loggerToMatch value="Noisy.Namespace.But.Important" />
</filter>
<filter type="log4net.Filter.LoggerMatchFilter">
  <!-- ...but not the rest of it -->
  <loggerToMatch value="Noisy.Namespace" />
  <acceptOnMatch value="false" />
</filter>

You need to create a logger just for your namespace

<logger name="YourNamespace.SubNamespace">
    <appender-ref ref="YourAppender" />
</logger>

Then only logging in that namespace will be sent to YourAppender.
