Helper para ConfigurationElementCollection

leave a comment »

Interesante utilidad que ayuda muchísimo para trabajar con colecciones en archivos de configuración.

    [ConfigurationCollection(typeof(ConfigurationElement))]
    public class ConfigurationElementCollection<T> :
        ConfigurationElementCollection, IEnumerable<T> where T : ConfigurationElement, new()
    {
        protected override ConfigurationElement CreateNewElement()
        {
            return new T();
        }
        protected override object GetElementKey(ConfigurationElement element)
        {
            return ((T)(element)).ToString();
        }
        public T this[int idx]
        {
            get { return (T)BaseGet(idx); }
        }

        public new IEnumerator<T> GetEnumerator()
        {
            int count = base.Count;
            for (int i = 0; i < count; i++)
                yield return base.BaseGet(i) as T;
        }
