[NET]深度拷貝的實現(DeepCopy)

實現思想：  對象-〉序列化-〉二進位流-〉還原序列化-〉新的對象

DotNet 代碼：

    public static  Object DeepClone(Object srcObject)
      {
           //定義記憶體流
           MemoryStream ms=new MemoryStream();
           //定義二進位流
           IFormatter bf=new BinaryFormatter();
           //序列化
           bf.Serialize(ms,srcObject);
           //重設指標到起始位置，以備還原序列化
           ms.Position=0;
           //返回還原序列化的深複製對象
           return bf.Deserialize(ms);

      } 

 

Java 代碼：

 public static Object deepClone(Object srcObject) throws IOException,
   ClassNotFoundException {
  
  ByteArrayOutputStream bo = new ByteArrayOutputStream();
  ObjectOutputStream oo = new ObjectOutputStream(bo);
  oo.writeObject(srcObject);

  ByteArrayInputStream bi = new ByteArrayInputStream(bo.toByteArray());
  ObjectInputStream oi = new ObjectInputStream(bi);
  
  return oi.readObject();
 }
