C# CollectionBase,ICloneeable

就目前我对CollectionBase的理解>public class Cards : CollectionBase

继承此类可以对List进行相关操作

 public void Add(Card newCard)      {         List.Add(newCard);         //foreach (card card in list)         //{         //    console.writeline("element is {0}",card);            //}         //Console.WriteLine("List length is {0}", List.Count);         //for (int i = 0; i < List.Count; i++)         //{         //    Console.WriteLine("element {0} is {1}", i, List[i]);         //}      }

ICloneable 是复制内容的接口

 public class Card : ICloneable   {           public object Clone()      {         return MemberwiseClone();      }
