Hi Anjo: I checked my code again and it does work as expected (I did have a pretty comprehensive unit test for it). However, you have very sharp eyes and your version also works just fine. When list.Count - index == chunkSize, either the left side or right side of the equation will get you the same thing.

Thanks for the comment. It was a good brain excercise.

(list.Count - index) gives the number of remaining elements including the index element. So it doesn’t have to be greater than chunkSize, rather greater than or equal.

I think this line:

int count = list.Count - index > chunkSize ? chunkSize : list.Count - index;

should be:

int count = list.Count - index >= chunkSize ? chunkSize : list.Count - index;

Thanks for the post - helped me with a problem I was having.
