How do I create editable configuration settings in a C# WinForms application?

Question

I have configuration values saved in an app.config. I want to create a WinForms application which shows all the AppSettings values in a form. The user should be able to change the settings values and save them back to the app.config.

As long as your values are in the appConfig section of the app.config file, you can simply use System.Configuration.ConfigurationManager.

ConfigurationManager.AppSettings - MSDN
