C# various values in app.config

Question

In a C# 2008 application I have code like what is listed below. Thread.CurrentPrincipal.IsInRole(Environment.UserDomainName + \ + Role) I want to change the code so the role value is obtained from the app.config file instead of having a hard-coded value of role. Thus can you show me some code how I can obtain the Role value from the app.config file instead of using hard-coded values?

Try: string role = System.Configuration.ConfigurationManager.AppSettings[Role]; You need to add a reference to System.Configuration.dll to your project if there isn't one already.
