持久化一个对象

1.对象与文件之间序列化/反序列化

       public static void SerializeToFile<T>(T obj,string dataFile)        {            using (FileStream fileStram = File.Create(dataFile))            {                BinaryFormatter binSerializer = new BinaryFormatter();                binSerializer.Serialize(fileStram, obj);            }        }        public static T DeserializeFromFile<T>(string dataFile)        {            T obj = default(T);            using (FileStream fileStream = File.OpenRead(dataFile))            {                BinaryFormatter binSerializer = new BinaryFormatter();                obj =(T)binSerializer.Deserialize(fileStream);            }            return obj;        }

测试：

       static void Main(string[] args)        {            ArrayList list = new ArrayList() { "Zero", "One", "Two" };            SerializeHelper.SerializeToFile(list, "HT.data");            ArrayList list2 = SerializeHelper.DeserializeFromFile<ArrayList>("HT.data");            foreach (var item in list2)            {                Console.WriteLine(item.ToString());            }            Console.ReadKey();        }

2.对象与字节流之间序列化/反序列化

        public static byte[] Serialize<T>(T obj)        {            using (MemoryStream memStream = new MemoryStream())            {                BinaryFormatter binSerializer = new BinaryFormatter();                binSerializer.Serialize(memStream, obj);                return memStream.ToArray();            }        }        public static T Deserialize<T>(byte[] serializedObj)        {            T obj = default(T);            using (MemoryStream memStream = new MemoryStream(serializedObj))            {                BinaryFormatter binSerializer = new BinaryFormatter();                obj = (T)binSerializer.Deserialize(memStream);            }            return obj;        }
