Log4net writes data to the SQL database, log4netsql

Log4net writes data to the SQL database, log4netsql

Recently, some user behaviors need to be added to the database, so I thought of using log4net. If there are other good solutions, you can correct me.

Let's take a look at the configuration file. This is the console file app. config.

<Layout type = "LogTest. MyLayout, LogTest"> <param name = "ConversionPattern" value = "% property {Log_Type}"/> </layout>
This is a custom parameter.

<? Xml version = "1.0" encoding = "UTF-8"?> <Configuration> <configSections> <section name = "log4net" type = "log4net. config. log4NetConfigurationSectionHandler, log4net "/> </configSections> <log4net> <root> <level value =" ALL "> </level> <appender-ref =" ADONetAppender "/> </root> <! -- Sqldatabase --> <appender name = "ADONetAppender" type = "log4net.

NETFramework, Version = v4.5 "/> </startup> </configuration>

MyLayout is a ing Class.

Public class MyLayout: PatternLayout {public MyLayout () {this. addConverter ("property", typeof (MyMessagePatternConverter);} public class MyMessagePatternConverter: PatternLayoutConverter {protected override void Convert (System. IO. textWriter writer, log4net. core. loggingEvent loggingEvent) {if (Option! = Null) {// Write the value for the specified key WriteObject (writer, loggingEvent. repository, LookupProperty (Option, loggingEvent);} else {// Write all the key value pairs WriteDictionary (writer, loggingEvent. repository, loggingEvent. getProperties ());}} /// <summary> /// obtain the value of an attribute of the input log object through reflection /// </summary> /// <param name = "property"> </param> // <returns> </returns> private object LookupPrope Rty (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 ;}}

 

Console

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace LogTest {    class Program {        static void Main(string[] args) {            log4net.Config.XmlConfigurator.Configure();            log4net.ILog log = log4net.LogManager.GetLogger(typeof(Program));            log.Info(new ASM_Log { au_ID = 1, Log_Content = "11", Log_Type = "s", Log_Object = "3", Log_Url = "sss" });            Console.ReadKey();        }    }    public class ASM_Log {        public int au_ID { set; get; }        public string Log_Object { set; get; }        public string Log_Type { set; get; }        public string Log_Content { set; get; }        public string Log_Url { set; get; }    }}

 

 

Because projects are connected to other projects, you can reference existing projects as needed.
