Problem regarding LoggerManager

Hi,

I really need help on this issue. I've looked for a solution everywhere but
haven't found one.
Here is my problem:

In the company I work for, A log4net wrapper is being used in order to write
logs into files (and database). The problem is, that when I try to write
details as line number and file name into the log file, I get question
marks, and it happens IN DEBUG MODE, where I have a pdb file.

I've done some testing and found out that it happens only when I use
LoggerManager object. If I use LogManager object it works just fine.

Here is how I use it:

The Log.config:

<logger name="CodeExamples.Program">
      <level value="DEBUG"/>
      <appender-ref ref="Global" />     
 </logger>

<appender name="Global" type="log4net.Appender.RollingFileAppender">      
            
      
      
      
            
      
     
      <layout type="log4net.Layout.PatternLayout">
        
                
        
      </layout>
    </appender>

This piece of code prints out the question marks:
private ILogger logger;
log4net.Config.XmlConfigurator.ConfigureAndWatch(new
FileInfo("D:\\Projects\\CodeExamples\\bin\\Debug\\Log.config"));
logger = LoggerManager.GetLogger(Assembly.GetCallingAssembly(),
MethodBaseType.FullName);
logger.Log(MethodBaseType, Level.Error, Message, null);

Here is its output:
[07 06 2010 16:11:09,343] ERROR: Attempted to divide by zero.; Logger:
CodeExamples.Program; File: ?; Line: ?; Type: ?;

This one works just fine:
private ILog log;
log4net.Config.XmlConfigurator.ConfigureAndWatch(new
FileInfo("D:\\Projects\\CodeExamples\\bin\\Debug\\Log.config"));
log = LogManager.GetLogger(Assembly.GetCallingAssembly(),
MethodBaseType.FullName);
log.Error(Message, null); 


and the output:
[07 06 2010 16:11:09,365] ERROR: Attempted to divide by zero.; Logger:
CodeExamples.Program; File: D:\Projects\MyLogger\MyLog.cs; Line: 41; Type:
MyLogger.MyLog;


If I could, I would use only LogManager, but the wrapper I work with uses
the LoggerManager, and touching it is the last thing I want to do...

Any help will be appreciated!

Thanks.

Sorry. The param part just vanished.. here is the main part of it:

param name="ConversionPattern" value="%newline[%date{dd MM yyyy
HH:mm:ss,fff}] %level: %message; Logger: %logger{3}; File: %file; Line:
%line; Type: %type;%newline"

Thanks a lot.
In the meantime I changed the object that I work with into LogManager
(instead of LoggingManager) and it works just fine.
Thanks anyway!

Your wrapper needs to pass its Type into log4net's Log method so the code that processes StackTrace information knows to skip over certain frames:

http://code.google.com/p/mybatisnet/source/browse/tags/cs%20release%201.3/IBatisNet.Common.Logging.Log4Net/Log4NetLogger.cs

public class MyCompanysWrapperLogger : ILog
{

 private readonly static Type _declaringType = typeof(MyCompanysWrapperLogger);
 private ILogger _log4netLogger;

 internal MyCompanysWrapperLogger(ILog log)
 {
  _log4netLogger = log.Logger;
 }

 public void Info(object message, Exception e)
 {
  _logger.Log(declaringType, log4net.Core.Level.Info, message, e);
 }
}
