log4net write to a separate file

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.");
}

log4net is not logging to log file or console (external log4net.config file)

I created a a file called log4net.config in my project and added the following configuration:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
</configSections>
<log4net>
<root>
<level value="ALL" />
<appender-ref ref="console" />
<appender-ref ref="RollingFileAppender" />
</root>
<appender name="console" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %level %logger - %message%newline" />
</layout>
</appender>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="${LOCALAPPDATA}\MyApp\LogFile.log" />
<param name="AppendToFile" value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%-5level [%d{yyyy-MM-dd hh:mm:ss}] [%thread] (Line:%line) %M: - %m%n" />
</layout>
</appender>
</log4net>
</configuration>
After that, I added the line below to my AssemblyInfo.cs file:
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]
In the application, I have the following static class:
public static class Logger
{
private static readonly ILog log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
public static void LogInfo(string msg)
{
log.Info(msg);
}
public static void LogDebug(string msg)
{
log.Debug(msg);
}
public static void LogWarn(string msg, Exception e)
{
log.Warn(msg, e);
}
public static void LogError(string msg, Exception e)
{
log.Error(msg, e);
}
}
Then I'm trying to log somewhere in the application in another class using Logger.LogDebug("Error logger working.");
However, I can't see any log file being created or written to it. What am I doing wrong?
UPDATE:
I also added the following in my app.config file but I see nothing at all on my Output console...
<appSettings>
<add key="log4net.Internal.Debug" value="true"/>
</appSettings>

If you have the log4net configuration in a log4net logging configuration file, you do not have to add the configuration of the web.config (configuration tag and sections). Just add the log4net tags:
<log4net>
<root>
<level value="ALL" />
<appender-ref ref="console" />
<appender-ref ref="RollingFileAppender" />
</root>
<appender name="console" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %level %logger - %message%newline" />
</layout>
</appender>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="${LOCALAPPDATA}\MyApp\LogFile.log" />
<param name="AppendToFile" value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%-5level [%d{yyyy-MM-dd hh:mm:ss}] [%thread] (Line:%line) %M: - %m%n" />
</layout>
</appender>
</log4net>

I could not reproduce your mistake. Configure log4net in AssemblyInfo works fine. maybe the problem in configuration. let me show you another implementation
private static readonly ILog log = LogManager.GetLogger("myLogger");
private static string configFile = "log4net.config";
static Logger()
{
XmlConfigurator.Configure(new FileInfo(configFile));
}
log4net.config:
<log4net>
<logger name="myLogger">
<level value="ALL" />
<appender-ref ref="console" />
<appender-ref ref="RollingFileAppender" />
</logger>
<appender name="console" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %level %logger - %message%newline" />
</layout>
</appender>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="${LOCALAPPDATA}\MyApp\LogFile.log" />
<param name="AppendToFile" value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%-5level [%d{yyyy-MM-dd hh:mm:ss}] [%thread] (Line:%line) %M: - %m%n" />
</layout>
</appender>
</log4net>

Managed to find out the issue thanks to stuartd's comment. My problem was, my full solution had 2 projects. I had only configured one project (which is not the start-up project) for log4net.
My original log4net configuration did not have any mistake. I simply added log4net reference to my start up project and added log4net configuration to that project as well and it started logging.
Many thanks to everyone who tested my config.

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">
<file type="log4net.Util.PatternString" value="C:\NinjaTraderLogs\NinjaLogs.txt" />
<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">
<file type="log4net.Util.PatternString" value="C:\NinjaTraderLogs\NinjaLogs_Fatal.txt" />
<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>
<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.

Use log4net with separate config file

my AssemblyInfo.cs:
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "Log4Net.config", Watch = true)]
i change the structure just like you said
(i just change the <file value="..\Logs\\CurrentLog" /> to <file value="D:\Log\Log.txt" />):
<?xml version="1.0" encoding="UTF-8"?>
<log4net>
<root>
<level value="ALL" />
<appender-ref ref="RollingFileAppender"/>
</root>
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="D:\Log\Log.txt" />
<appendToFile value="true" />
<datePattern value="yyyyMMdd" />
<rollingStyle value="Date" />
<filter type="log4net.Filter.LevelRangeFilter">
<acceptOnMatch value="true" />
<levelMin value="INFO" />
<levelMax value="FATAL" />
</filter>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern
value="%-5p %d %5rms %-22.22c{1} %-18.18M - %m%n" />
</layout>
</appender>
</log4net>
and define the log:
private static readonly ILog Log = LogManager.GetLogger("Logger");
but still the log.txt file doesn't created yet!

There's something missing in your config file.
<log4net>
<logger name="default">
<level value="ALL"/>
</logger>
<root>
<level value="ALL" />
<appender-ref ref="RollingLogFileAppender" />
</root>
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="..\Logs\\CurrentLog" />
<appendToFile value="true" />
<datePattern value="yyyyMMdd" />
<rollingStyle value="Date" />
<filter type="log4net.Filter.LevelRangeFilter">
<acceptOnMatch value="true" />
<levelMin value="INFO" />
<levelMax value="FATAL" />
</filter>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern
value="%-5p %d %5rms %-22.22c{1} %-18.18M - %m%n" />
</layout>
</appender>
</log4net>
And also the declaration:
private static readonly ILog Log = LogManager.GetLogger("default");

Actually, you haven't declared a logger in your config and it has wrong structure.
This is how it should look like:
<?xml version="1.0" encoding="UTF-8"?>
<log4net>
<logger name="Logger">
<level value="ALL" />
<appender-ref ref="RollingFileAppender"/>
</logger>
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="..\Logs\\CurrentLog" />
<appendToFile value="true" />
<datePattern value="yyyyMMdd" />
<rollingStyle value="Date" />
<filter type="log4net.Filter.LevelRangeFilter">
<acceptOnMatch value="true" />
<levelMin value="INFO" />
<levelMax value="FATAL" />
</filter>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern
value="%-5p %d %5rms %-22.22c{1} %-18.18M - %m%n" />
</layout>
</appender>
</log4net>
Now you can access it this way:
private static readonly ILog Log = LogManager.GetLogger("Logger");
It definitely works.
Now about your code snippet. I'm not sure about your initialization. I haven't worked with log4net this way:
private static readonly ILog Log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
However, you can try declaring logger in root and initialize it:
<?xml version="1.0" encoding="UTF-8"?>
<log4net>
<root>
<level value="ALL" />
<appender-ref ref="RollingFileAppender"/>
</root>
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="..\Logs\\CurrentLog" />
<appendToFile value="true" />
<datePattern value="yyyyMMdd" />
<rollingStyle value="Date" />
<filter type="log4net.Filter.LevelRangeFilter">
<acceptOnMatch value="true" />
<levelMin value="INFO" />
<levelMax value="FATAL" />
</filter>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern
value="%-5p %d %5rms %-22.22c{1} %-18.18M - %m%n" />
</layout>
</appender>
</log4net>
// ...
private static readonly ILog Log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);

Log4Net Message log

I am trying to use log4net for my web service. the problem that I am facing is that, when I try to send multiple messages at the same time, it's only creating the log for the first message.
The log is working fine when we send only one message at a time and wait until the message has reached the listener. But when we shoot multiple messages at the same time (without waiting for the response at the listener), it's only logging the first message that I sent.
Here is my configuration. Can anyone please let me know what I am missing:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
</configSections>
<log4net>

</root>

<stringToMatch value="Log" />
</filter>

Did you try setting your lock model to
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
