4, Program.cs add code

using log4net;
using System;
using System.Reflection;

namespace SendEvaluateDataToProvinceConsole
{
    class Program
    {
        /// <summary>
        /// logging log objects
        /// </summary>
        public static ILog Log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
        static void Main(string[] args)
        {
            //log4net.Config.XmlConfigurator.ConfigureAndWatch(new System.IO.FileInfo(@"F:\Person\Longteng\LongtengSln\SendEvaluateDataToProvince\App.config"));
            log4net.Config.XmlConfigurator.Configure (); // This is something very important. . . . .
            try
            {
                Log.Info("123...");
                Log.Info ( "Ordinary log");
                Log.Error ( "Error Log");
                Log.Debug ( "anomalies");
                Log.Fatal ( "Fatal Error");
                Log.Warn ( "warnings");
                
                LogEntity logEntity = new LogEntity
                  {
                    //Id= "123",
                    UserId = "123",
                    UserName = "Joe Smith"
                    Message = "Message of the Western Xia Xiong"
                    Exception = "Exception"
                    };
 
                   Log.Debug(logEntity);
                   Console.Read();
            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message);
                Console.WriteLine(e.Source);
                Console.WriteLine(e.StackTrace);
                Console.WriteLine(e.InnerException != null ? e.InnerException.ToString() : "");
                Console.ReadLine();
            }
        }        
    }
}

 

5, operating results

 

 

6, the operation result of FIG. Note that some data is not right, the object is inserted LogEntity is, an object is displayed instead of the specific data corresponding to the object

LogEntity logEntity = new LogEntity
{
//Id= "123",
UserId = "123",
UserName = "张三",
Message = "消息西夏熊",
Exception = "Exception"
};

Analyze the reasons is because LogEntity is custom objects, log4net LogEntity not know what it is, so we converted it to convert into objects LogEntity log4net know, can, in fact, is to modify the log4net PatternLayout display mode,

code show as below:

First built MyPatternConverter classes, inheritance log4net class of PatternLayoutConverter

using log4net.Core;
using log4net.Layout.Pattern;
using System.IO;
using System.Reflection;

namespace SendEvaluateDataToProvinceConsole
{
    public class MyPatternConverter : PatternLayoutConverter
    {
        protected override void Convert(TextWriter writer, LoggingEvent loggingEvent)
        {
            if (Option != null)
                WriteObject(writer, loggingEvent.Repository, LookupProperty(Option, loggingEvent));
            else
                WriteDictionary(writer, loggingEvent.Repository, loggingEvent.GetProperties());
        }

        // Get the value of the incoming log object through the reflection of a property
        private object LookupProperty(string property, log4net.Core.LoggingEvent loggingEvent)
        {
            object propertyvalue = string.Empty;
            PropertyInfo propertyInfo = loggingEvent.MessageObject.GetType().GetProperty(property);

            if (propertyInfo != null)
                propertyvalue = propertyInfo.GetValue(loggingEvent.MessageObject, null);
            return propertyvalue;
        }
    }
}

 

Then the new MyLayout classes, inheritance log4net class of PatternLayout

using log4net.Layout;

namespace SendEvaluateDataToProvinceConsole
{
    public class MyLayout : PatternLayout
    {
        public MyLayout()
        {
            this.AddConverter("Property", typeof(MyPatternConverter));
        }
    }
}

After the above classes and built MyPatternConverter MyLayout class, modify the configuration file as follows App.config

<?xml version="1.0" encoding="utf-8"?>

  <configSections>
    <-! Custom configuration section of log4net ->
