Performance Tricks for C# Logging
- by Charles
I am looking into C# logging and I do not want my log messages to spend any time processing if the message is below the logging threshold. The best I can see log4net does is a threshold check AFTER evaluating the log parameters.
Example:
_logger.Debug( "My complicated log message " + thisFunctionTakesALongTime() + " will take a long time" )
Even if the threshold is above Debug, thisFunctionTakesALongTime will still be evaluated.
In log4net you are supposed to use _logger.isDebugEnabled so you end up with
if( _logger.isDebugEnabled )
_logger.Debug( "Much faster" )
I want to know if there is a better solution for .net logging that does not involve a check each time I want to log.
In C++ I am allowed to do
LOG_DEBUG( "My complicated log message " + thisFunctionTakesALongTime() + " will take no time" )
since my LOG_DEBUG macro does the log level check itself. This frees me to have a 1 line log message throughout my app which I greatly prefer. Anyone know of a way to replicate this behavior in C#?
