A very useful log4net logging library

stay .net In the project , Regular use log4net Class library to record the project log , If you need to record which class and which method , It is often necessary to define a static attribute in each class , Used to get which class and which method . This article introduces the use of reflection technology , Get the caller's class and method name .

     First , At the program entrance , Initialize logging , Otherwise, the log file cannot be generated automatically .

  Logger.Initialize();

Later, you can reference this library anywhere , Use logging .

        /// <summary>        ///  Start screen recording         /// </summary>        public string StartCaptureScreen()        {
               if (RecordScreenParameter == null)            {
                   Logger.Debug($" Screen recording parameters {nameof(RecordScreenParameter)} It's empty , Unable to perform screen recording ！");                            }            if (!RecordScreenParameter.IsEnabled)            {
                   Logger.Debug($" You have not enabled the screen recording parameter {nameof(RecordScreenParameter.IsEnabled)}, Unable to perform screen recording ！");                            }          }

Error log

 try {
     } catch (Exception ex)            {
                   Logger.Error(ex.Message);            };

So how to get the method name of the caller through reflection technology , Here is the core code ​​​​​​​

  public static void Debug(object message)        {
               MethodBase method = new System.Diagnostics.StackTrace().GetFrame(1).GetMethod();            var logger = LogManager.GetLogger(method.DeclaringType);#if DEBUG            Console.WriteLine(message);#endif            logger?.Debug(message);        }

The complete code is as follows ：

using log4net;using System.Reflection;namespace System{       /// <summary>    ///  Logging class     /// </summary>    public class Logger    {
           /// <summary>        ///  initialization ILog        /// </summary>        public static void Initialize()        {
               LogManager.GetLogger(typeof(Logger));        }        public static void Debug(object message)        {
               MethodBase method = new System.Diagnostics.StackTrace().GetFrame(1).GetMethod();            var logger = LogManager.GetLogger(method.DeclaringType);#if DEBUG            Console.WriteLine(message);#endif            logger?.Debug(message);        }
        public static void Info(object message)        {
               MethodBase method = new System.Diagnostics.StackTrace().GetFrame(1).GetMethod();            var logger = LogManager.GetLogger(method.DeclaringType);#if DEBUG            Console.WriteLine(message);#endif            logger?.Info(message);        }
        public static void Warn(object message)        {
               MethodBase method = new System.Diagnostics.StackTrace().GetFrame(1).GetMethod();            var logger = LogManager.GetLogger(method.DeclaringType);#if DEBUG            Console.WriteLine(message);#endif            logger?.Warn(message);        }
        public static void Error(object message)        {
               MethodBase method = new System.Diagnostics.StackTrace().GetFrame(1).GetMethod();            var logger = LogManager.GetLogger(method.DeclaringType);#if DEBUG            Console.WriteLine(message);#endif            logger?.Error(message);        }
        public static void Fatal(object message)        {
               MethodBase method = new System.Diagnostics.StackTrace().GetFrame(1).GetMethod();            var logger = LogManager.GetLogger(method.DeclaringType);#if DEBUG            Console.WriteLine(message);#endif            logger?.Fatal(message);        }    }}
