Spartaco Giubbolini commented on LOG4NET-217:
---------------------------------------------
If log.IsXXXEnable is all you need then you can easily solve it with extension
methods, no need to change the interface, at least for this purpose.

> Key: LOG4NET-217
> URL: https://issues.apache.org/jira/browse/LOG4NET-217
> Project: Log4net
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.2.10
> Reporter: Fabio Maulo
> Priority: Minor
> Fix For: 3.5
>
>
> 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.
