RE: Excluding stack trace from Layout

Yann,
Thanks for the reply.
I guess I could do

catch (Exception ex)
{
if (log.IsWarnEnabled)
 log.Warn(string.Format("Error blah {0}:{1}\n{2}\n{3}", key1, key2, ex.Message, ex.InnerException));
}

Instead, I would prefer to pass in the exception
log.Warn(string.Format("error blah {0}:{1}", key1,key2 ), ex);

I want to use an exception layout to selectively log parts of the exception.
I'll use a text file appender to log the stack trace and every gory detail and use an SMTP appender to semd me just the exception message and InnerException.  And I can change what gets logged at any time.

I see from the SDK that there is an exception layout but I just cant figure out what I need to do.

regards
Habib
