Question

I have some list (where T is a custom class, and class has some properties). I would like to know how to change one or more values inside of it by using Lambda Expressions,

I know this is an old post but, I've always used an updater extension method:

      public static void Update(this IEnumerable outer, Action updator)
        {
            foreach (var item in outer)
            {
                updator(item);
            }
        }

list.Where(w => w.Name == "height").ToList().Update(u => u.height = 30);
