Get log4net log file in C#

This is my configuration for log4net:

<log4net>
    <appender name="MyLogger" type="log4net.Appender.RollingFileAppender">
        <file value="MyLog.log" />
        <appendToFile value="true" /> 
        <rollingStyle value="Size"/>
        <maxSizeRollBackups value="20"/>
        <maximumFileSize value="1000KB"/>
        <layout type="log4net.Layout.PatternLayout">
            <param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss},%p,%m%n" />
        </layout>
    </appender>
    <root>
        <level value="DEBUG" />
        <appender-ref ref="MyLogger" />
    </root>
</log4net>

In C# I'm trying to get the name of the log file (which is MyLog.log). I googled and tried many things but failed to do so. Any help?

Thanks!
