Log4Net - Different Log Files, Different Log Levels.

Just writing to help other developer like me,

Problem: I wanted to log different LOG Levels in different files using LOG4Net.

my app.config was like this.



log4net
appender name="LogFileAppender" type="log4net.Appender.FileAppender"
param name="File" value="..\..\Logs\ApplicationLog.log"
param name="AppendToFile" value="false"
layout type="log4net.Layout.PatternLayout"
param name="Header" value=""
param name="Footer" value=""
param name="ConversionPattern" value="%d [%t] %-5p %m%n"
layout
appender

appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender"
layout type="log4net.Layout.PatternLayout"
param name="Header" value="[Header]\r\n"
param name="Footer" value="[Footer]\r\n"
param name="ConversionPattern" value="%d [%t] %-5p %m%n"
layout
appender
root
level value="ALL"
appender-ref ref="ConsoleAppender"
appender-ref ref="LogFileAppender"
root

log4net

-------------------------------------------------------------------------------------
I added different Appenders for file saving and Logger tag to define my new loggers
(Check TEXT in Green)

---------------------------------------------------------------------------------------------
My LOG4Net Level ENUM was look like this before;
---------------------------------------------------------------------------------------------

public enum ELogLevel
{

DEBUG = 1,

ERROR,

FATAL,

INFO,

WARN,
}
---------------------------------------------------------------------------------------------
I added my new LOG4Net Levels (Check Text in green )
---------------------------------------------------------------------------------------------

public enum ELogLevel
{

DEBUG = 1,

ERROR,

FATAL,

INFO,

WARN,

INPUT,

OUTPUT

}

---------------------------------------------------------------------------------------------
My LOG4Net Class was look like this before;
---------------------------------------------------------------------------------------------

public static class CLogger
{

#region Members

private static readonly ILog logger = LogManager.GetLogger(typeof(CLogger));


#endregion



#region Constructors

static CLogger()
{

XmlConfigurator.Configure();
}

#endregion



#region Methods



public static void WriteLog(ELogLevel logLevel, String log)
{

if (logLevel.Equals(ELogLevel.DEBUG))
{

logger.Debug(log);

}

else if (logLevel.Equals(ELogLevel.ERROR))
{

logger.Error(log);

}

else if (logLevel.Equals(ELogLevel.FATAL))
{

logger.Fatal(log);

}

else if (logLevel.Equals(ELogLevel.DEBUG))
{

logger.Info(log);

}

else if (logLevel.Equals(ELogLevel.WARN))
{

logger.Warn(log);

}

else if (logLevel.Equals(ELogLevel.INFO ))
{

logger.Info (log);

}
}


-----------------------------------------------------------------------------------------------
I wrote code for my new LOGGER in config (check text in green)
-----------------------------------------------------------------------------------------------





public static class CLogger
{

#region Members

private static readonly ILog logger = LogManager.GetLogger("LogFileAppender");
private static readonly ILog errorlogger = LogManager.GetLogger("ErrorFileAppender");
private static readonly ILog inputDataLog = LogManager.GetLogger("InputLogger");
private static readonly ILog outputDataLog = LogManager.GetLogger("OutputLogger");



#endregion



#region Constructors

static CLogger()
{

XmlConfigurator.Configure();
}

#endregion



#region Methods



public static void WriteLog(ELogLevel logLevel, String log)
{

if (logLevel.Equals(ELogLevel.DEBUG))
{

logger.Debug(log);

}

else if (logLevel.Equals(ELogLevel.ERROR))
{

errorlogger.Error(log);

}

else if (logLevel.Equals(ELogLevel.FATAL))
{

logger.Fatal(log);

}

else if (logLevel.Equals(ELogLevel.DEBUG))
{

logger.Info(log);

}

else if (logLevel.Equals(ELogLevel.WARN))
{

logger.Warn(log);

}

else if (logLevel.Equals(ELogLevel.INFO ))
{

logger.Info (log);

}
else if (logLevel.Equals(ELogLevel.INPUT ))
{

inputDataLog.Info(log);

}

else if (logLevel.Equals(ELogLevel.OUTPUT ))
{

outputDataLog.Info(log);

}


}



After all this, now i can save my Input and Out level messages to different files and Debug and Error in one file.


Thanks
