log4net write to a separate file - c#

Is possible to write to a specific file when referencing a given appender?
Currently even if I reference to "RollingFile2" I am still writing to example.log file, instead of example2.log file
App.Config
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>
<log4net>
<appender name="Console" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<!-- Pattern to output the caller's file name and line number -->
<conversionPattern value="%5level [%thread] (%file:%line) - %message%newline" />
</layout>
</appender>
<appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
<file value="example.log" />
<appendToFile value="true" />
<maximumFileSize value="100KB" />
<maxSizeRollBackups value="2" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%level %thread %logger - %message%newline" />
</layout>
</appender>
<appender name="RollingFile2" type="log4net.Appender.RollingFileAppender2">
<file value="example2.log" />
<appendToFile value="true" />
<maximumFileSize value="100KB" />
<maxSizeRollBackups value="2" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%level %thread %logger - %message%newline" />
</layout>
</appender>
<root>
<level value="DEBUG" />
<appender-ref ref="Console" />
<appender-ref ref="RollingFile" />
</root>
</log4net>
</configuration>
Code
private static readonly ILog log = LogManager.GetLogger("RollingFile2");
static void Main()
{
log.Info("Entering application.");
log.Info("Exiting application.");
}

Two log4net configuration files on same solution

I have an solution which consist of multiple projects.its a desktop application I need to have two separate log4net configurations for those projects since one project contains a library that uses log4net itself. On one project log4net configured in App.config and other project it is configured in log4net.configuration file.
below is one configuration file
'''

</logger>
</log4net>
those two log file load correctly but they all write on to the same log file seperatelog.txt
What i need is to have two separate files to create for those 2 configurations.
Seems you'll better define log4net configuration not in app.config but in dedicated XML files. Names of XML files can be composed according to some convention so your projects will know what log4net configuration XML is dedicated to each one.
You'll able to configure your log4net with XmlConfigurator.Configure(...) function

c# log4net fillappend nothing happen

I need use log4net create a .txt and write log into .txt I did not konw what happen log4net not do anyting no create .txt and write log.
This is my log4net.config

this is Program.cs use log.info() and log.error
private static readonly log4net.ILoglog = log4net.LogManager.GetLogge(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
static void Main(string[] args)
{
log.Info("log_info");
log.Error("log_error");
}
this is assemblyinfo.cs
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]
I found the problem, I have two .config one is App.config two is log4net.config if only write "log4net.config" ,it will not found the log4net.config.So need write the log4net.config path it will work.
[assembly: log4net.Config.XmlConfigurator(ConfigFile = #"C:\Users\username\Documents\Visual Studio 2015\Projects\Log\Log\log4net.config", Watch = true)]

log4net not logging errors and fatal in separate file

I tried to separate the errors and fatal into separate log file not i dont see it logging in separate file. here is my config file. can you point what mistake i made?
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>
<log4net>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">

<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="5" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %level (%property{method}) (%property{state}) (%property{instrument}) - %message%newline" />
</layout>
<level value="All" />
</appender>
<appender name="FatalError" type="log4net.Appender.RollingFileAppender">

<appendToFile value="true" />

<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %level (%property{method}) (%property{state}) (%property{instrument}) - %message%newline" />
</layout>
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="ERROR" />
<levelMax value="FATAL" />
</filter>
</appender>
<root>
<appender-ref ref="RollingFileAppender" />
</root>
</log4net>
</configuration>
Create one more appender ref as below under <root>
<root>
<appender-ref ref="RollingFileAppender" />
<appender-ref ref="FatalError" />
</root>
Before you call your logging in code make sure to call the XmlConfigurator function Configure (call it globally) like
log4net.Config.XmlConfigurator.Configure();
Last but not least, make sure you have write permission to the directory you are trying to create log file. I would suggest you to check windows event log once Application log to see if any error has happened.

Load only one appender instead of all

I'm currently working on a console C# app and I have to log two type of data :
All steps of the app in general (AppLog)
All information that I get from a service (MachineLog)
MachineLog needs 2 propeties, but when I start the app I do not define them I have some work to do before. But I need to log from start whith AppLog so at le beginning I use :
log4net.Config.XmlConfigurator.Configure();
And it create me the C:\DNC\Suivi\Logs.txt but also C:\DNC\Suivi\(null)\(null)-logs.txt
Is there any way to only load/configure AppLog and later MachineLog ?
I tried to add parameters to Configure() and all failed.
My App.config is :
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net"/>
</configSections>
<log4net>
<root>
<level value="DEBUG" />
<appender-ref ref="AppLog" />
</root>
<logger name="Machine" additivity="false">
<level value="ALL" />
<appender-ref ref="MachineLog" />
</logger>
<appender name="AppLog" type="log4net.Appender.RollingFileAppender">
<file value="C:\DNC\Suivi\Logs.txt" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
</appender>
<appender name="MachineLog" type="log4net.Appender.RollingFileAppender" >
<file type="log4net.Util.PatternString" value="C:\DNC\Suivi\%property{Machine}\%property{ID}-logs.txt" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
</appender>
</log4net>
</configuration>
With your current configuration, you can't do it. As you have seen, log4net will create the log files when XmlConfigurator.Configure() is called.
In order to this, you will have to do at least some work programmatically, once you know where the file will be - it's quite easy to set the file name at runtime so you can have a placeholder file name in the config, then set the correct name at runtime when the values are known. This does mean that the empty placeholder file will exist - the only way around that would be to create the whole appender at runtime.

log4net is not creating log file to log

log4net is not creating any text file to log. I tried like this
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
</configSections>
<log4net>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file type="log4net.Util.PatternString" value="EpinovaADSyncJob.log" />
<appendToFile value="false" />
<rollingStyle value="Composite" />
<staticLogFileName value="false" />
<datePattern value="yyyy-MM-dd" />
<preserveLogFileNameExtension value="true"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - %message%newline%exception" />
</layout>
</appender>
<root>
<level value="INFO"/>
<appender-ref ref="RollingFileAppender"/>
<appender-ref ref="ConsoleAppender" />
</root>
</log4net>
</configuration>
In assembly file:
[assembly: log4net.Config.XmlConfigurator(
ConfigFile = "Log4Net.config", Watch = true)]
Declared as class variable
private static readonly ILog Log = LogManager.GetLogger(
MethodBase.GetCurrentMethod().DeclaringType);
In a method, called the Log like this
BasicConfigurator.Configure();
Log.Debug("Myjob");
Log.Error("newlkjasdf");
Log.Info("lkjlkjasdfasdf");
Try this appender :
<appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="log.txt" />
<appendToFile value="false" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="-1" />
<maximumFileSize value="10MB" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%-5p%d{yyyy-MM-dd hh:mm:ss} – %m%n" />
</layout>
