Achieving color magazines with Log4net

Question

Now, Iam get error "could not find the" log4net "configuration section in the .config file application." This is my code in the log4net.config file:

 <?xml version="1.0" encoding="utf-8" ?> <log4net> <configuration> <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" /> </configSections> <root> <level Value="Info"/> <level Value="Error"/> <appender-ref ref="ColoredFileAppender" /> </root> <appender name="ColoredFileAppender" type="log4net.Appender.RollingFileAppender" > <file type="log4net.Util.PatternString"/> <file value="C:\CL2.html" /> <encoding value="utf-8" /> <lockingModel type="log4net.Appender.FileAppender+MinimalLock" /> <appendToFile value="false" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%CC" /> <converter> <name value="CC" /> <type value="Cluster2.ColoredMessageConverter" /> </converter> <mapping> <level value="Info" /> <foreColor value="Green" /> </mapping> <mapping> <level value="ERROR" /> <backColor value="Red, HighIntensity" /> </mapping> </layout> </appender> </configuration> </log4net> 

I included this statement in the assembly:

 [assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)] 

I included this expression in my program:

 protected void Application_start(Object Sender, EventArgs e) { log4net.Config.XmlConfigurator.Configure(); } 

I have no idea what the problem is. Please, help.

To achieve this, you need to use your own template, and then include it in the log4net.config file. Your code will look like this:

 public class ColoredMessageConverter : PatternLayoutConverter { protected override void Convert(TextWriter writer, LoggingEvent loggingEvent) { string color = ""; switch (loggingEvent.Level.Name) { case "DEBUG": color = "green"; break; case "WARN": case "INFO": color = "white"; break; case "ERROR": color = "pink"; break; case "FATAL": color = "red"; break; } string logToRender = string.Format(" <p style='color:{0}'>{1}</p>", color, loggingEvent.RenderedMessage); //Add logToRender to file writer.Write(logToRender); } } 

In your log4net.config, connect this converter as shown below. Replace "Your namespace" with the correct one.

 <log4net> <root> <level value="DEBUG" /> <appender-ref ref="ColoredFileAppender" /> </root> <appender name="ColoredFileAppender" type="log4net.Appender.RollingFileAppender" > <file type="log4net.Util.PatternString" value="c:\test.html" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%CC" /> <converter> <name value="CC" /> <type value="<<Your namespace>>.ColoredMessageConverter" /> </converter> </layout> </appender>
