Configure log4net RollingFileAppender when scrolling code after launching the application

I would like to create a log4net RollingFileAppender that creates a new file every time the program starts. It can roll if the file gets large, but it should roll every time the application starts. The application should not be added if another application is configured in the setting. Essentially creating a default log configuration that you can override by modifying the configuration file.

After compiling a few other posts, I finally got this job. The implementation is performed in a static wrapper class. All you have to do is paste this code into your application, set the location to create the file and call Log.Configure () when the application starts.

using log4net;
using log4net.Core;
using log4net.Appender;
using log4net.Repository.Hierarchy;
using System.Reflection;
using System.IO;

namespace [Your Namespace]
{
    public static class Log
    {
        private static bool isConfigured = false;
        private static ILog iLog;

        public static void Configure()
        {
            if (isConfigured)
                return;

            var loggerName = typeof(DiagnosticsManager).FullName;

            var logger = (log4net.Repository.Hierarchy.Logger)log4net.LogManager.GetRepository().GetLogger(loggerName);
            var ilogger = log4net.LogManager.GetRepository().GetLogger(loggerName);

            //Add the default log appender if none exist
            if(logger.Appenders.Count == 0)
            {
                var directoryName = "[Your directory name here. e.c. 'C:\ProgramData\AppName\Logs']";

                //If the directory doesn't exist then create it
                if(!Directory.Exists(directoryName))
                    Directory.CreateDirectory(directoryName);

                var fileName = Path.Combine(directoryName, "[Your static file name here. e.c. 'AppName.log']");

                //Create the rolling file appender
                var appender = new log4net.Appender.RollingFileAppender();
                appender.Name = "RollingFileAppender";
                appender.File = fileName;
                appender.StaticLogFileName = true;
                appender.AppendToFile = false;
                appender.RollingStyle = log4net.Appender.RollingFileAppender.RollingMode.Size;
                appender.MaxSizeRollBackups = 10;
                appender.MaximumFileSize = "10MB";
                appender.PreserveLogFileNameExtension = true;

                //Configure the layout of the trace message write
                var layout = new log4net.Layout.PatternLayout()
                {
                    ConversionPattern = "%date{hh:mm:ss.fff} [%thread] %-5level - %message%newline"
                };
                appender.Layout = layout;
                layout.ActivateOptions();

                //Let log4net configure itself based on the values provided
                appender.ActivateOptions();
                log4net.Config.BasicConfigurator.Configure(appender);
            }

            iLog = LogManager.GetLogger(loggerName);
            isConfigured = true;

            Info("Logging Configured at " + DateTime.Now.ToString("g"));
        }

        public static event EventHandler<ExceptionLoggedEventArgs> ExceptionLogged;

        public static void Debug(object message) { Configure(); iLog.Debug(message); }
        public static void Debug(object message, Exception exception) { Configure(); iLog.Debug(message, exception); }

        public static void Error(object message) { Configure(); iLog.Error(message); }
        public static void Error(object message, Exception exception) { Configure(); iLog.Error(message, exception); }

        public static void Fatal(object message) { Configure(); iLog.Fatal(message); }
        public static void Fatal(object message, Exception exception) { Configure(); iLog.Fatal(message, exception); }

        public static void Info(object message) { Configure(); iLog.Info(message); }
        public static void Info(object message, Exception exception) { Configure(); iLog.Info(message, exception); }

        public static void Warn(object message) { Configure(); iLog.Warn(message); }
        public static void Warn(object message, Exception exception) { Configure(); iLog.Warn(message, exception); }

    }
