以递增方式序列化对象？

Question

我知道如何将一个对象序列化为一个字节数组，但是它将整个序列化，有没有办法将它序列化为一块kb？例如，我有一个对象，它将序列化为4mb的大字节数组，而不是同时序列化整个对象，我想一次序列化1kb块，所以它会序列化1kb的价值和传递它，然后继续下一个，直到它完全序列化。我该怎么做呢？

我当前的序列化/反序列化类：

using System;
using System.Windows.Forms;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.Serialization.Formatters.Binary;
using System.IO;

namespace TCP_Handler
{
    public class SerialMediator
    {

        /// <summary>
        /// Serializes a packet into a byte array
        /// </summary>
        /// <param name="pkt"></param>
        /// <returns></returns>
        public static Byte[] Serialize(Packet pkt)
        {
            BinaryFormatter bf = new BinaryFormatter();
            MemoryStream ms = new MemoryStream();
            bf.Serialize(ms, (Object)pkt);
            return ms.ToArray();
        }

        /// <summary>
        /// Deserializes a packet from a byte array
        /// </summary>
        /// <param name="arr"></param>
        /// <returns></returns>
        public static Packet Deserialize(Byte[] arr)
        {
            BinaryFormatter bf = new BinaryFormatter();
            MemoryStream ms = new MemoryStream();
            ms.Write(arr, 0, arr.Length);
            ms.Seek(0, SeekOrigin.Begin);
            try
            {
                return (Packet)bf.Deserialize(ms);
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
                throw new Exception("Byte array did not represent a packet");
            }
        }
    }
}
