Question

Let’s say I have a list of objects, and I want to sort it by the items DateModified property. Why can’t I use a delegate like this? How should I sort these by DateModified if not as shown below:

public string SortByDateModified(List<CartItem> items)
{
    items.Sort(new Func<CartItem, CartItem, bool>((itemA, itemB) =>
    {
        return itemA.DateModified < itemB.DateModified;
    }));
}

Answer 1

Why not use a lambda expression?

public string SortByDateModified(List<CartItem> items) 
{ 
    items.Sort((a, b) => a.DateModified.CompareTo(b.DateModified)); 
}
