Subject AW: Log4Net RollingFileAppender not adding Custom property in Win8/VS2013
Date Wed, 07 Jan 2015 12:06:23 GMT


Here’s a list of things that you could check:


*         First of all enable log4net’s internal debug logging, it may give
you a clue what he is doing

*         Make sure to call log4net.Config.XmlConfigurator.Configure() after
setting the property

*         Escape path separators properly

*         Specify the rolling style to be used


Beware that using a patternstring for  the file property of a
rollingfileappender is a hot hack and you might get burned as soon as
rolling jumps in!

Betreff: Log4Net RollingFileAppender not adding Custom property in


Hi All

I am creating a custom property in Log4Net with Visual Studio 2010 on Win7
and it is able to create everything well with the correct property. But If i
try to run the same program on Win8 and Visual Studio 2013, it do create the
log file but without the custom property.

I have not edited anything and same thing is working in WIn7 but not in

I don't know what is changing in both of these environments. Can anyone give
hint at what to look for?

<?xml version="1.0" encoding="utf-8" ?>



    <section name="log4net"
type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />



  <appender name="CsvFileAppender"

    <file type="log4net.Util.PatternString"
value="C:\TSAS_DRU_Log\%property{LogName}" />

    <appendToFile value="true"/>

    <maxSizeRollBackups value="10"/>

    <maximumFileSize value="100MB"/>

    <staticLogFileName value="true"/>

    <layout type="TSAS_DRU_app.CsvPatternLayout, TSAS_DRU_app">




    <level value="DEBUG" />

    <appender-ref ref="CsvFileAppender" />





I am setting the property in the code as following which is working
correctly in WIn7 but not in Win8 where I have just updated the Visual
studio as version 2013 with 2010:

string LogName = "TSAS_DRU_Log_" + date + ".csv";

    log4net.GlobalContext.Properties["LogName"] = LogName;
