Bah! Forget those crazy configuration objects. Use Linq to XML on it:

var seccion = 
    XDocument.Load(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile)
        .Root.Element("Seccion");

// Now Linq to XML until your heart's content!
var user = (string)seccion.Element("BD").Elements("add")
    .Where(x => (string)x.Attribute("key") == "user")
        .Single().Attribute("value");

Thank for your answer, but I'd be worried if memory use was exponential based on the size of the XML document. How can I do to read XDocument from Cache. – Townshend

You would only use this once, statically initialized of course. Not sure how big you think a .config should get, or why you think it's any different than other methods of accessing the .config file. – Weisbart

You can probably deserialize it to the custom section type:

var section = ConfigurationManager.GetSection("Seccion") as ManejoConfiguracion.SeccionConfig;
