Log4net using and configuring a log file per day

1. Download or install log4net in NuGet



2. Web. config (app. config)

<configuration>   <configSections> <section name= "log4net"           type= "log4net. Config.log4netconfigurationsectionhandler,         log4net "/> </configSections> <log4net>        < Appender name= "Rollinglogfileappender" type= "log4net. Appender.rollingfileappender ">    <file type=" log4net. Util.patternstring "Value=" C:\M1\EDASLOG\%DATE{DD. Mm.yyyy}.txt "/>    <appendtofile value=" true "/>    <rollingstyle value=" Date "/>    < Datepattern value= "YyyyMMdd"/>    <layout type= "log4net. Layout.patternlayout ">        <conversionpattern value=" [[%date]]-%message%newline "/>    </layout ></appender><root><level value= "DEBUG"/><appender-ref ref= "Rollinglogfileappender"/> </root>    </log4net></configuration>

For a log file every day. To do this configuration (the file node type is patternstring):

<file type= "log4net. Util.patternstring "Value=" C:\M1\EDASLOG\%DATE{DD. Mm.yyyy}.txt "/>

3. Apply the configuration. In Application_Start (for Web Apps), configure ():

Log4net. Config.XmlConfigurator.Configure ();

4. Do a simple wrapper to use:

public static class Edaslogger    {        private static log4net. ILog Log {get; set;}        Static Edaslogger ()        {            Log = log4net. Logmanager.getlogger (typeof (Logger));                    }        public static void Error (Object msg)        {            log.error (msg);        }        public static void Error (Object msg, Exception ex)        {            log.error (msg, ex);        }        public static void Error (Exception ex)        {            log.error (ex). Message, ex);        }        public static void Info (Object msg)        {            log.info (msg);        }    }
