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)

        /// 这个是序列化
        /// </summary>

            MemoryStream streamMemory = new MemoryStream();
            formatter.Serialize(streamMemory, data);
            byte[] binaryData = streamMemory.GetBuffer();
            streamMemory.Close();
            return binaryData;
        }

            object data = formatter.Deserialize(streamMemory);
            streamMemory.Close();
