Question

Suppose I have an ordered list of float (ascending).

I want to remove from it each element whose difference between next element and itself is less than a given threshold.

I need something like this:

List<float> orderedList;

IEnumerable<float> query = orderedList.Where(currentNum , nextNum => nextNum - currentNum < threshold);

Is that possible? If yes how?

Try this –

List<float> orderedList = new List<float>() { 12, 14, 34, 45 };
List<float> itemsToRemove = orderedList.Where((item, index) =>
                            index < orderedList.Count - 1 &&
                            orderedList[index + 1] - item < threshhold).ToList();
