深拷貝與淺拷貝接口

子類繼承拷貝父類，直接調用拷貝方法，子類需要序列化：

 

    [Serializable]
    public class Cloneable<T> : ICloneable
    {
        public object Clone()
        {
            return MemberwiseClone();
        }
        public T DeepClone()
        {
            using (Stream objs = new MemoryStream())
            {
                var formatter = new BinaryFormatter();
                formatter.Serialize(objs, this);
                objs.Seek(0, SeekOrigin.Begin);
                return (T)formatter.Deserialize(objs);
            }
        }
    }

調用：

    [Serializable]
    public class a: Cloneable<a>
    {
        public int num;
    }
