While I have no doubt that this thing can be done by either using the Config
Application Block from the Enterprise Library or by implementing a config
section handler (as suggested in the two replies I got for my initial
question), here is how I did it w/o adding any new implementation or
application block to my project. Just in case someone else out there is
trying to solve it right now.
The app.config file looks like this:
<configuration>
<configSections>
<sectionGroup name="customGroup">
<sectionGroup name="customSection">
<section name="cfgSet1"
type="System.Configuration.NameValueSectionHandler"/>
<section name="cfgSet2"
type="System.Configuration.NameValueSectionHandler"/>
</sectionGroup>
</sectionGroup>
</configSections>
<appSettings>
<add key="CustomConfigSetCounter" value="2" />
</appSettings>
<customGroup>
<customSection>
<cfgSet1>
<add key="Param_1" value="Val_11"/>
<add key="Param_2" value="Val_12"/>
<add key="Param_3" value="Val_13"/>
</cfgSet1>
<cfgSet2>
<add key="Param_1" value="Val_21"/>
<add key="Param_2" value="Val_22"/>
<add key="Param_3" value="Val_23"/>
</cfgSet2>
</customSection>
</customGroup>
</configuration>
The code to access it looks like this:
UInt32 nConfigSetCounter = Convert::ToUInt32(
ConfigurationSettings::AppSettings->Get( S"CustomConfigSetCounter" ) );
for( UInt32 i=1; i<=nConfigSetCounter; i++ )
{
Object *pTempObj = ConfigurationSettings::GetConfig( String::Format(
S"customGroup/customSection/cfgSet{0}", i.ToString() ) );
NameValueCollection *pKeyValuePairs = dynamic_cast<NameValueCollection
*>(pTempObj);
Console::WriteLine( S"Config Set # {0}", i.ToString() );
if( pKeyValuePairs != 0 )
{
IEnumerator *pEnumKeys = pKeyValuePairs->GetEnumerator();
while( pEnumKeys->MoveNext( ) )
{
String *pKey = dynamic_cast<String *>(pEnumKeys->Current);
Console::WriteLine( "Key {0} - Value {1}", pKey,
pKeyValuePairs->Get( pKey ) );
}
}
Console::WriteLine( S"" );
}
This is Managed C++, but you get the idea. For simplicity, I left out all
the error handling that I would normally add to it.
Cheers,
Eddie

You can have this in a custom config file and use Configuration
Application Block to integrate with it. One requirement from your side
will be to define a class for the custom config file, for serialization
purposes. Some of the advantages you gain from using Configuration
Application Block are
1. Respond to config changes at runtime, easily.
2. Persisting the modified configuration values.

Hi Ed,
Best solution for you is to implement a Config Section of your own and
read it from your own class.
To implement a configsection handler, all you have to do is implement
IConfigurationSectionHandler interface.
If you have msdn you can copy/paste this url it will be helpful :
