vb.net 2010 obtain values from app.config file

[classy_dog]

In a vb.net 2010 desktop application that uses the .net framework 3.5, I would like the application to return app.config file values back to the area that is obtaining the values from the config file.

When I look at the code in the following section url: https://msdn.microsoft.com/en-us/library/system.configuration.configurationmanager.appsettings(v=vs.100).aspx , it does not really tell me how to obtain values from the app.config file and return the values to the area that called the app.config file. Basically I need to obtain a large volume of directory path values from the app.config file.

Thus would you show me the code on how to accomplish this goal?
