How to set value to NLog.config

I am just wondering ho开发者_如何学JAVAw to change the value in NLog.config file from other file configuration for example,

<variable name="logDirectory" value="${basedir}/logs/${shortdate}"/>

I want to change logDirectory value to be "C:/logs/${shortdate}" and of course I want to get the value from other configuration file. Is it possible to do that?

thanks in advance.
