Programmatically adding log4net appenders

I needed to programamatically add a log4net appender at runtime, the docs for all of this are all a little fuzzy so just for future reference

class FileCleanerAppender : RollingFileAppender

{

public FileCleanerAppender()

{

File = "Foo.log";

AppendToFile = false;

RollingStyle = RollingMode.Once;

LockingModel = new MinimalLock();

Name = "SomeAppender";

Layout = new PatternLayout { ConversionPattern = "%m" };

ActivateOptions();

}

}

((log4net.Repository.Hierarchy.Logger)LogManager.GetLogger("SomeLogger").Logger)

.AddAppender(new FileCleanerAppender());
