ConfigurationManager.AppSettings["appsettings"]; needs to be ConfigurationManager.AppSettings[""]; — Mike Miller, Jan 03 '14 at 13:37

It looks like you are trying to retrieve all the values you are keeping in Configuration.AppSettings. To do this try using ConfigurationManager.Appsettings.AllKeys then you can do:

        var settings = ConfigurationManager.AppSettings.Keys;

        foreach (string setting in settings)
        {
            symbols.Add(ConfigurationManager.AppSettings[setting]);
        }
