Convert IEnumerable to EntitySet Using Extension Methods
published on 5/29/2008 11:14:58 AM

Recently, I had a requirement to convert an IEnumerable to EntitySet. Off course, you can create a helper class with a separate convert method but I think this scenario qualifies for Extension Methods. Here is the ToEntitySet code which converts an IEnumerableto EntitySet

  // convert IEnumerable to an EntitySet
        public static EntitySet<T> ToEntitySet<T>(this IEnumerable<T> e) where T : class
        {
            if (e == null || e.Count() == 0)
                throw new ArgumentException("List null or does not contains any elements");

            EntitySet<T> set = new EntitySet<T>();
            set.AddRange(e);
            return set;            
        }
