Can someone explain, in plain English, the difference between ConfigurationSection and ConfigurationElement?

I'm reading through a fantastic article on the .NET Configuration namespace (found here) which talks about creating custom sections, elements, collections, widgets, 开发者_JAVA技巧and flying toasters. The only complaint I have is that the article is only technical and doesn't provide any conceptual context. MSDN doesn't appear to have much conceptual information, either.

So can someone explain, please, what a "section" is, what an "element" is, and when it would be appropriate to use each?

I think a better read for you will be this series of articles, which brilliantly tells you about all the details of configurations in C#:

And to answer your question in simple words, ConfigurationSection is a container which contains multiple ConfigurationElement and/or ConfigurationElementCollection. The parent of ConfigurationSection will always be <configuration> which is the root element in configuration files.

ConfigurationElement is a container and/or single element and is always part of a ConfigurationSection.
