The following is a simple way to setup log4net to log actions using the file appender. You can get log4net using Nuget in Visual Studio (right-click your project references -> Manage Nuget Packages...).

If you want to create a separate file for log4net configs (ex: log4net.config), you must update your Global.asax.cs file in the Application_Start section (code at bottom).

<!-- Web.config --> <configuration> <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" /> </configSections> ... <!-- Parent Section is configuration --> <log4net> <root> <!-- add other appenders here and the log messages will be sent to every listed appender --> <appender-ref ref="LogFileAppender" /> <level value="ALL"/> </root> <!-- The DebugFileAppender writes all messages to a log file--> <appender name="LogFileAppender" type="log4net.Appender.FileAppender"> <file value="C:\\Projects\\Logs\\Testing.log" /> <appendToFile value="true" /> <lockingModel type="log4net.Appender.FileAppender+MinimalLock" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%d [%t] %-5p %c %m%n" /> </layout> </appender> </log4net> ... </configuration> //C# Code log4net.Config.XmlConfigurator.Configure(); log4net.ILog log = log4net.LogManager.GetLogger("LogFileAppender"); log.Error("Error Message"); log.Debug("Debug Message"); log.Fatal("Fatal Message"); log.Info("Info Message"); log.Warn("Warning Message"); //seperate log config file protected void Application_Start() { ... log4net.Config.XmlConfigurator.ConfigureAndWatch(new System.IO.FileInfo(AppDomain.CurrentDomain.BaseDirectory + "log4net.config")); }
