将列表分成N个较小的列表

public static List<List<float[]>> SplitList(List<float[]> locations, int nSize=30)  { var list = new List<List<float[]>>();    for (int i = 0; i < locations.Count; i += nSize)     {         list.Add(locations.GetRange(i, Math.Min(nSize, locations.Count - i)));     }    return list; }

通用版本：

public static IEnumerable<List<T>> SplitList<T>(List<T> locations, int nSize=30)  { for (int i = 0; i < locations.Count; i += nSize)     {         yield return locations.GetRange(i, Math.Min(nSize, locations.Count - i));     }  }
