My Project is in C# (Windows Form) .net3.5
In my code there are multiple events and in each event multiple searches are running.
I have to create log file for each event and multiple searches can access & write this single log file.
The problem is that I don't know how to use log4net for creating multiple logs with dynamic(set at run time) names.
How to set there location(Path)
I explorer internet regarding my problem but haven't found any help which address this type of issues.
any idea pls
log4net is generally used to have mutiple sources and appenders.
To generate a defined source, ask LogManager to have a named log, generally we use a type to identify a log, but feel free to use a string if you want:
var myLog = LogManager.GetLogger("NAME");
....
var myLog = LogManager.GetLogger(GetType());
In the first case logger is identified by "NAME", in the second by the type name with namespaces.
Then you can configure the appenders, for all logs, for a subset of them, with filters and so on.
Let's see an example:
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
</configSections>
<log4net>
<appender name="MYFILE" type="log4net.Appender.RollingFileAppender">
<file value=".\logs\myname.log"/>
<appendToFile value="true"/>
<rollingStyle value="Size"/>
<maxSizeRollBackups value="10"/>
<maximumFileSize value="10MB"/>
<staticLogFileName value="true"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %-5level (%thread) %logger - %message%newline"/>
</layout>
</appender>
<root>
<level value="INFO"/>
<!-- all logger append to these appenders />
<appender-ref ref="xxxxxx"/>
</root>
<logger name="NAME">
<level value="INFO"/>
<appender-ref ref="MYFILE"/>
</logger>
<!-- add other appender here -->
Don't forget to call at your application start XmlConfigurator.Configure();
