这很可爱：
static class ChunkExtension{ public static IEnumerable<T[]> Chunkify<T>( this IEnumerable<T> source, int size) { if (source == null) throw new ArgumentNullException("source"); if (size < 1) throw new ArgumentOutOfRangeException("size"); using (var iter = source.GetEnumerator()) { while (iter.MoveNext()) { var chunk = new T[size]; chunk[0] = iter.Current; for (int i = 1; i < size && iter.MoveNext(); i++) { chunk[i] = iter.Current; } yield return chunk; } } }}static class Program{ static void Main(string[] args) { List<byte> bytes = new List<byte>() { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 }; var chunks = bytes.Chunkify(4); foreach (byte[] chunk in chunks) { foreach (byte b in chunk) Console.Write(b.ToString("x2") + " "); Console.WriteLine(); } }}
