log4net/c# - Different layout based on the level

Question

Is there any way to have different layout based on level of the log message when using log4net? Say, if it is a fatal error, I want to see all kind of information possible - class name, method name, line number etc. But for normal, debug and warning, I want to see only the message (I hope, this can increase the performance). I am using log4net in C# WinForms. My requirement is to log all the previous 512 messages in to a file when a fatal error occures, and I want to see class name, method name, line number etc only for Fatal errors, for all other levels, just a message.

Answer 1

 For LevelRangeFilter and a two-appender combination. One appender/filter combo for FATAL level (fatal being the min and max) and one appender/filter combo for everthing else (with ERROR or INFO being the max depending on if you wanted to include errors for debugging purposes)
