Why isn't there a trace level in log4Net?

Question

I was just wondering why there isn\'t a trace level in log4Net. This level seems to be missing and I sometimes feel the need to use it, for example to output what events are bei

You can add a Verbose (or Trace level) to log4net by using extension methods. This is what I'm using:

public static class ILogExtentions
{       
    public static void Trace(this ILog log, string message, Exception exception)
    {
        log.Logger.Log(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType, 
            log4net.Core.Level.Trace, message, exception);
    }

    public static void Trace(this ILog log, string message)
    {
        log.Trace(message, null);
    }

    public static void Verbose(this ILog log, string message, Exception exception)
    {
        log.Logger.Log(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType, 
            log4net.Core.Level.Verbose, message, exception);
    }

    public static void Verbose(this ILog log, string message)
    {
        log.Verbose(message, null);
    }

}

Usage example:

public class ClientDAO
{
    private static readonly log4net.ILog log = log4net.LogManager.GetLogger(typeof(ClientDAO));

    public void GetClientByCode()
    {
        log.Trace("your verbose message here");
        //....
    }
}
