public class DataProviders : IConfigurationSectionHandler
{
    private static bool _initialized;
    public static List _providers;

    public object Create(object parent, object configContext, XmlNode section)
    {
        XmlNodeList providers = section.SelectNodes("Provider");

        _providers = new List();

        foreach (XmlNode provider in providers)
        {
            _providers.Add(new Provider
            {
                Type = provider.Attributes["type"].Value,
                Alias = provider.Attributes["alias"].Value,
            });
        }

        return null;
    }

    public static void Init()
    {
        if (!_initialized)
        {
            ConfigurationManager.GetSection("DataProviders");
            _initialized = true;
        }
    }

    public static IEnumerable GetData(string dataProviderAlias)
    {
        return _providers.Where(p => p.Alias == dataProviderAlias);
    }
}

public class Provider
{
    public string Type { get; set; }
    public string Alias { get; set; }
}
