refreshing TraceSwitch settings

[Kevin Meiresonne]

I have developed an XML-based tracelistener which uses a booleanswitch
(enable/disable), a general traceswitch (set the tracelevel) and a
userspecific traceswitch (set the tracelevel for a particular user).
Those switches are set in app.config

Now I am looking for a way to know when these settings in my app.config have
changed (for example, when changing the tracelevel) at runtime, so that my
application can use the new settings.
When I check traceSwitch.Lev el in my code while debugging, it seems that it
doesn't use the new level until I restart the application.

Is there a way to "refresh" this dynamically at runtime without having to
restart the application?

My config file looks like this:
<?xml version="1.0" encoding="utf-8" ?>
<configuratio n>
<system.diagnos tics>
<switches>
<add name="GeneralBo oleanSwitch" value="1" />
<add name="GeneralTr aceSwitch" value="1" />
<add name="UserSpeci ficTraceSwitch" value="4" />
</switches>
<trace autoflush="true " indentsize="2">
<listeners>
<add name="MyTraceLi stener"
type="..."
initializeData= "..."/>
<remove name="Default" />
</listeners>
</trace>
</system.diagnost ics>
<appSettings>
<add key="UserSpecif icTraceUsers" value="User1,Us er2" />
....
</appSettings>
</configuration>
