Split List into Sublists with LINQ

Question

Is there any way I can separate a List into several separate lists of SomeObject, using the item index as the delimiter of each s

Answer 1

This following solution is the most compact I could come up with that is O(n).

public static IEnumerable Chunk(IEnumerable source, int chunksize)
{
    var list = source as IList ?? source.ToList();
    for (int start = 0; start < list.Count; start += chunksize)
    {
        T[] chunk = new T[Math.Min(chunksize, list.Count - start)];
        for (int i = 0; i < chunk.Length; i++)
            chunk[i] = list[start + i];

        yield return chunk;
    }
}
