In .Net 1.1-, there is a good example to write our own appSettings handler l
ike http://www.codeproject.com/dotnet/namevaluemultiple.asp?df=100&forumid=1
5760&select=2229833&msg=2229833. But in .Net 2.0+, it doesn't work any more.
Any solution?

you can implement custom section handlers. start from here:
http://msdn2.microsoft.com/en-us/library/ms228062(VS.80).aspx
you don't need to be limited to using appSettings and can
define your own structure of configuration

l
more.

Having a project using appSettings like the link I had given; I tried MSDN
suggestion, it doesn't allow the customized section name like appSettings.

It always claims "[System.Configuration.ConfigurationErrorsException] = {"
Configuration system failed to initialize"}"

Microsoft has removed the ability to remove section handlers, which means
that
we can NOT deregister the default appSettings handler and register a new one
. Microsoft reduced configurability flexibility by preventing the removal of
section handlers.

i guess that's because they introduced ConfigurationManager class
in 2.0 to ease working with appSettings and connectionStrings (thru
ConfigurationManager.AppSettings and ConfigurationManager.ConnectionStrings).
they probably don't want you to replace handlers for these sections
with your own.
for new code, i'd suggest (as in my previous post) to implement your own
section handlers, which gives you much more flexibility than appSettings,
etc
you can support whatever schemas you design in configu
