序列化和反序列化

序列化是将类型转化为二进制类型，可以保存到文件，或者用于传输

反序列化是将二进制类型转化为文本等类型

这个是对象的序列化

   #region 对象的序列化与反序列化(字节)

        /// <summary>

        /// 这个是序列化

        /// </summary>

        /// <param name="data"></param>

        /// <returns></returns>

        public static byte[] Serialize(object data)

        {

            BinaryFormatter formatter = new BinaryFormatter();

            MemoryStream streamMemory = new MemoryStream();

            formatter.Serialize(streamMemory, data);

            byte[] binaryData = streamMemory.GetBuffer();

            streamMemory.Close();

            return binaryData;

        }



        /// <summary>

        /// 这个是反序列化

        /// </summary>

        /// <param name="binaryData"></param>

        public static object Deserialize(byte[] binaryData)

        {

            BinaryFormatter formatter = new BinaryFormatter();

            MemoryStream streamMemory = new MemoryStream(binaryData);

            object data = formatter.Deserialize(streamMemory);

            streamMemory.Close();

            return data;
