Log4net for windows service

.net, app-config, c#-4.0

Solution

Try This:

 <log4net>
    <root>
      <level value="Error" />
      <appender-ref ref="RollingLogFileAppender" />
    </root>
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="<FilePath>" />
      <appendToFile value="true" />
      <rollingStyle value="Composite" />
      <maxSizeRollBackups value="14" />
      <countDirection value="1" />
      <maximumFileSize value="4096KB" />
      <lockingModel type="log4net.Appender.FileAppender.MinimalLock" />
      <staticLogFileName value="true" />
      <PreserveLogFileNameExtension value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%newlineDate[%date] ThreadID[%thread] Level[%-5level] Logger[%logger]] - %message%newline" />
      </layout>
    </appender>
  </log4net>

In addition to this there should be a entry of Log4Net in Config Section, Example:

<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net"/>
  </configSections>
</configuration>

In your Logger class have `ILog` variable and in constructor configure the logger like this:

private ILog log;

public Log4NetLogger()
{
    log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
    log4net.Config.XmlConfigurator.Configure();
}

Problem

This is first time I am using `Log4net`. It doesn't show any errors, but is not writing to file. I added following in my `AppConfig` file: ``` <configuration> <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" requirePermission="false"/> </configSections> <log4net> <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender"> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%5level [%thread] (%file:%line) - %message%newline"/> </layout> </appender> <appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="C:\CE\FileControllerLog.txt"/> <layout type="log4net.Layout.PatternLayout">  <param name="ConversionPattern" value="%d %m%n"/> </layout> <appendToFile value="true"/> <rollingStyle value="Composite"/> <maxSizeRollBackups value="2"/> <maximumFileSize value="10MB"/> <staticLogFileName value="true"/> </appender> <logger name="FileControllerLog"> <level value="INFO"/> <appender-ref ref="LogFileAppender" /> <appender-ref ref="ConsoleAppender"/> </logger> ``` ``` [assembly: log4net.Config.XmlConfigurator(Watch = true)] //added in assembly info file ``` and in code: ``` ILog logger = log4net.LogManager.GetLogger("FileControllerLog"); logger.Info("Method starts"); ``` It's not logging.
