I'm new to tinkering with app.config and xml, and am currently doing some refactoring in some code I haven't written.
Currently we have a snippet which looks like this:

<setting name="FirstSetting" serializeAs="String">
  <value>Data Source=C:\Documents and Settings\All Users\ApplicationData\Company ...;Persist Security Info=False</value>

What I'd like to do is have it instead point to something like ${PROGRAMDATA}\Company\...

How can I achieve this, keeping in mind that PROGRAMDATA will not always point to C:\ProgramData ?

One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
