Reading and writing to a custom config in c#

Is there a lib in c# that will allow you to read and write to a config or some kind of profile?

I am not talking about the app.config but more like a custom.config similar to the ol .ini file where there were built in lib/functions to read/write to the profile.

I can of course write my own, but would like to know if there exists some common lib or ways to do this...

I know about custom config section but would prefer not to take that route.

Solution

I found what I am looking for. This will work:
