Implementation example using log4net in ASP. NET MVC

Today, I want to get a log recording function. I have done it before, but I forgot it. Today, I got it again. It took me a few 10 minutes to record it here.

Step 1: Add log4net. dll

Step 2: The configuration example is as follows: I am directly configured under Web. config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
 <configSections>
  <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
 </configSections>
 <log4net>
  <logger name="Student">
   <level value="ALL" />
   <appender-ref ref="rollingFile" />
  </logger>
  <appender name="rollingFile" type="log4net.Appender.RollingFileAppender,log4net">
   <File value="log/" />
   <DatePattern value="yyyy-MM-dd&quot;.txt&quot;" />
   <StaticLogFileName value="false" />
   <maxSizeRollBackups value="-1" />
   <RollingStyle value="Date" />
   <AppendToFile value="false" />
   <MaximumFileSize value="1024MB" />
   <layout type="log4net.Layout.PatternLayout,log4net">
    <ConversionPattern value="%-38m %-7p %-20d %n" />
   </layout>
  </appender>
 </log4net>
 
<!-- Not down there! ! ! -->
 <appSettings>
  <add key="webpages:Version" value="3.0.0.0" />
  <add key="webpages:Enabled" value="false" />
  <add key="ClientValidationEnabled" value="true" />
  <add key="UnobtrusiveJavaScriptEnabled" value="true" />
 </appSettings>
 <system.web>
  <compilation debug="true" targetFramework="4.7.2" />
  <httpRuntime targetFramework="4.7.2" />
 </system.web>
 
 
</configuration>

Step 3: Add log4net. Config. XmlConfigurator. Configure () under the Global. asax. cs file; As follows:

  public class MvcApplication : System.Web.HttpApplication
  {
    protected void Application_Start()
    {
      AreaRegistration.RegisterAllAreas();
      FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
      RouteConfig.RegisterRoutes(RouteTable.Routes);
      BundleConfig.RegisterBundles(BundleTable.Bundles);
      log4net.Config.XmlConfigurator.Configure();
    }
  }

Step 4: Add the Log helper class and then use it. Note here that the name corresponds to the comments in my code below

  public class LogHelper
  {
    //Student It's your configuration file  <logger name="Student">  Adj. name Value of 
    private static log4net.ILog log = log4net.LogManager.GetLogger("Student");
 
    public static void Debug(object message, Exception e)
    {
      log.Debug(message, e);
    }
 
    public static void Debug(object message)
    {
      log.Debug(message);
    }
 
    public static void Info(object message)
    {
      log.Info(message);
    }
 
    public static void Warn(object message)
    {
      log.Warn(message);
    }
 
    public static void Error(object message)
    {
      log.Error(message);
    }
 
    public static void Error(object message, Exception e)
    {
      log.Error(message, e);
    }
 
    public static void Log(object message)
    {
      log.Info(message);
    }
  }

The content of the configuration file is relatively simple and detailed. Look at other more detailed ones.
