如何在我的app.config中创建自定义部分？

Question

I'd like to add a custom section to my app.config. In that section, I'd like to add rows with three pieces of data. Then, I'd like to read my app.config (the custom section) and build a collection of items.

Can I create a customer section? If so, how do I create the section and how do I read items in it?

Thanks!

Answer 1

MSDN covers very throughly everything that you need on this topic. See How to: Create Custom Configuration Sections Using ConfigurationSection , System.Configuration.ConfigurationSection and the links therein.

Answer 2

You would create a custom section group and a handler to deal with that section group. The process is outlined the associated in MSDN article:

Answer 3

You'd create a descendant of ConfigurationSection . Microsoft's documentation contains an example of how to use it to make custom app.config sections.

Answer 4

The CodeProject article Unraveling the Mysteries of .NET 2.0 Configuration is probably the best piece I've seen on the hoops you need to jump through to build a custom config section.

There's also, the Coding Horror 's Last Configuration Section Handler I'll Ever Need and The Last Configuration Section Handler...Revisited , which avoid the problem by creating a generic XMLSerializationHandler: all you need to do is provide an class that is XML serializable. Easy!
