#### Parameters

message
  Type: System
  Object
  The message object to log.

Remarks

This method first checks if this logger is WARN enabled by comparing the level of this logger with the Warn level. If this logger is WARN enabled, then it converts the message object (passed as parameter) to a string by invoking the appropriate IObjectRenderer. It then proceeds to call all the registered appenders in this logger and also higher in the hierarchy depending on the value of the additivity flag.

WARNING Note that passing an Exception to this method will print the name of the Exception but no stack trace. To print a stack trace use the [M:Warn(object,Exception)] form instead.
