I have a huge IEnumerable(suppose the name is myItems), which way is more effective?
Solution 1: Filter it first then ForEach.
Array.ForEach(myItems.Where(FILTER-IT-HERE).ToArray(),MY-ACTION);
Solution 2: Do RETURN in MY-ACTION if the item is not up to the mustard.
Array.ForEach(myItems.ToArray(),MY-ACTION-WITH-FILTER);
Is one of them always better than another? Or any other good suggestions? Thanks in advance.
