Determine if logevent will actually log (ShouldLog)

[Mark Olszowka]

Is there a way to check if a logevent will actually get logged (based on the current configuration) before calling the Log method?

I need to do some code before calling the Log method that will affect performance, so i only want to do it if i know it will actually get logged.

Enterprise Library has something called ShouldLog that is used for this specific purpose.  Is there something similar in NLog?
