Recursing Through AppConfig File

Recursing Through AppConfig File

While doing some updates to the EmmCLA program (more to come on this soon), I needed to have it loop through all the AppSettings in in App.Config file (the same should hold true for Web.Config for web apps) to find all occurrences of appsettings that were similar to a certain string.

A few Google searches later led me to the solution of using System.Configuration.ConfigurationSettings.AppSettings.AllKeys which returns a string array of all the keys in the AppSettings portion of App.Config:

I’ve posted this in case anyone else finds a need to do something similar. This saved me a great deal of work and hopefully someone else will similarly benefit.

If you find this of some benefit, please leave us a comment below and let us know how you are using it.

I'm a technologist at heart, assisting companies best utilize the Internet to market themselves and sell their products and services online. This includes organizations as large as Google and as small as one or two individuals.
At Over The Top and Exhibit A Communications, I've programmed solutions for Google as well as at least one other company that was later acquired by Google.

I've been CTO of an Internet SaaS company and spent my time pretty evenly between guiding the future technical strategy of the company, architecting software solutions for my dev teams, designing and running a data center to service our clients world-wide as well as being a technical evangalist/sales engineer to our media clients large and small.

I've also been Chief Photographer of the Daily Sun/Post newspaper back when it was a 5-day a week daily newspaper.

I also spent a great many years as a beach lifeguardfor the City of San Clemente as well as Jr. Lifeguard instructor and then as it's program coordinator.
