Title: Message
Hello,
 
I'm interested in added method name data in my logging messages, so I've set up my RollingFileAppender like this:
<appender name="File - Support" type="log4net.Appender.RollingFileAppender">
  <param name="File" value="c:\\LogFiles\\ReferenceApp\\ReferenceApp" />
  <param name="AppendToFile" value="true" />
  <param name="DatePattern" value="  - yyyy-MM-dd.'log'" />
  <param name="RollingStyle" value="Date" />
  <param name="StaticLogFileName" value="false" />
  <layout type="log4net.Layout.PatternLayout">
   <param name="ConversionPattern" value="%-5p | %d{yyyy-MM-dd HH:mm:ss, fff} | %t | %c | %M | %t | %m%n" /> 
  </layout>
 </appender>
%M tells Log4Net to output the name of the method within which the logging statement was generated.
 
Now, I have Ceki Culcu's book for log4j (I was a Java developer in a previous life).  Within that he states:
On certain platforms, generating the caller class information can be excruciatingly slow.  Thus, the user of the C, F, l, L, and M conversion characters should be avoided unless execution speed is not an issue.
My question is, given that I'm using Log4Net (1.2.8b) and not Log4J and my platform is .NET 1.1, is this statement still true?  And if so, does anyone have any benchmarks indicating how much of a performance penalty will be taken for using the %M character?
 
Thanks,
Leo Hart
