Orderby/Sort a List of Lists based on the .Count
I have a list that countains lists of the type actorKnowledge
var scriptKnowledgeList = new List.<List.<ActorKnowledge> >();
What I would like to do is to sort the scriptKnowledgeList based on the size of each one of its items.
Lets say scriptKnowledgeList contains 3 elements that were added in the following order:
ListA.Count = 1;
ListB.Count = 5;
ListC.Count = 2;
I would like them to be re-ordered inside scriptKnowledgeList from bigger to smaller:
ListB.Count = 5;
ListC.Count = 2;
ListA.Count = 1;
How would I go about this? Thanks in advance!
UPDATE:
Ok, I think I got it, wondering if there is a better or more correct way of doing it?
scriptKnowledgeList = scriptKnowledgeList.OrderBy(function(x){return -x.Count;}).ToList();
scriptKnowledgeList.Sort (function (a : List.<ActorKnowledge>, b : List.<ActorKnowledge>) b.Count.CompareTo(a.Count));
Thanks for the quick reply. Which one is more correct/faster? The Sort or the OrderBy? Do they create the same end result?
The OrderBy is creating a new list so I assume the Sort is a little more efficient in terms of not generating garbage. I doubt there would be any noticeable performance difference either way.
