Can I get log4net to append the real class name and not the generated closure class name?

Question

I have a class that is logging from an anonymous method. I've dumbed it down to make the point...

public class SocketFlusher
{
    private static readonly ILog Log = LogManager.GetLogger(typeof(SocketFlusher));

    public void Flush()
    {
        Wait.For(timeout, () => 
        {
            ... // work
            Log.DebugFormat("{0} bytes available", socket.Available);
        }
    }
}

My log4net configuration is good (I've checked the log4net debug="true" output and the appender does work). My appender layout is

  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%-4thread] %-5level %class{1} - %message%newline"/>
  </layout>

But, my log output has that crazy auto-generated static class in it.

2011-03-21 18:10:20,053 [5   ] DEBUG SocketFlusher+<>c__DisplayClass1 - 82 bytes available

I want it to say SocketFlusher, what is the right appender layout to get this format?

Answer 1

You want the class name to appear in the appender output. And you're following the log4net idiom of naming your logger the name of the class...

private static readonly ILog Log = LogManager.GetLogger(typeof($CLASSNAME$));

What you want to do in the appender pattern layout is to include the %logger name pattern instead of the %class pattern.

<layout type="log4net.Layout.PatternLayout">
  <conversionPattern value="%date [%-4thread] %-5level %logger{1} - %message%newline"/>
</layout>
