• Discarding several log levels within a range with log4net

  - by Harel Moshe

  Hey, Say i set my log4net logger's minLevel and maxLevel to FATAL and DEBUG respectively, but under some scenario i want to mute the log-items written in the WARN level, and keep all the other levels in the range active. Is it possible to somehow use 'discrete' levels of log-levels rather than specifying a range using minLevel and maxLevel? I assume this should be simple, but i haven't found any log4net docs or examples dealing with this issue. Regards, Harel

• C# DLL: Need to know when application is closing

  - by Nick

  Is there a way to monitor when an application that is using the dll closes? The DLL and the application are both C#, neither are Windows Forms. I can check when the main application is closing, but I would like for the DLL to see "hey the program is closing and releasing me, I should do this real quick before I die". Any way to do it? Or am I stuck having the application dish out "do this before you die"?
