Subject [jira] Created: (LOG4NET-217) Delayed log
Date Wed, 03 Jun 2009 21:24:07 GMT
Delayed log
-----------

                 Key: LOG4NET-217
                 URL: https://issues.apache.org/jira/browse/LOG4NET-217
             Project: Log4net
          Issue Type: Improvement
          Components: Core
    Affects Versions: 1.2.11
            Reporter: Fabio Maulo
            Priority: Minor


would be useful an override like this
ILog.Debug(Func<string> messageDelegate);

callable as
log..Debug(()=> MyTimeExpensiveMethod);

This is to prevent boiled code as
if(log.IsDebugEnable)
{
log..Debug(MyTimeExpensiveMethod());
}

Log4Net can call the messageDelegate only when really needed.

If you want stay in NET2.0 you can create a specific delegate
public delegate string MessageDelegate;

Btw, IMO, the new version should target directly .NET3.5.
