Change logging level of Common.Logging.ILog logger backed by log4net logger, using reflection

gistfile1.txt

// This is just an example - requires error checking
// Due to reflection, it is not necessary to reference the log4net assembly

var iLog = LogManager.GetLogger(typeof(TcpStreamFactory));
var field = iLog.GetType().GetField("_logger", BindingFlags.Instance | BindingFlags.NonPublic);
var log4netlog = field.GetValue(iLog);
var propLogger = log4netlog.GetType().GetProperty("Logger");
var logger = propLogger.GetValue(log4netlog);
var propLevel = logger.GetType().GetProperty("Level");
var origLevel = propLevel.GetValue(logger);
var fieldOff = propLevel.PropertyType.GetField("Off", BindingFlags.Static | BindingFlags.Public);

propLevel.SetValue(logger, fieldOff.GetValue(null));
// do stuff with logger OFF
propLevel.SetValue(logger, origLevel); // restore level
