C#在於其他語言進行資料通訊時，直接傳遞的時二進位制的位元組碼，而一個要傳遞的物件的二進位制位元組碼在C#中有很多表示方法。其中直接轉換為Byte陣列和序列化未byte陣列，還有xml序列化，json序列化最未常用，下面簡單舉例介紹一下這幾種方法。

using System;
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;
using Newtonsoft.Json;


namespace Test1
{
    class Program
    {
        static void Main(string
 
[] args)
        {
            short i = 1024;
            short[] arrI = new short[] { 2, 4, 8, 16 };

            #region 位元組轉換測試程式

            byte[] intBuff = BitConverter.GetBytes(i);
            byte[] intArrBuff = new byte[arrI.Length * sizeof(short)];
            Buffer.BlockCopy(arrI, 0, intArrBuff, 0
 
, intArrBuff.Length);

            short rei = BitConverter.ToInt16(intBuff, 0);
            short[] reArrI = new short[intArrBuff.Length / sizeof(short)];
            Buffer.BlockCopy(intArrBuff, 0, reArrI, 0, intArrBuff.Length);


            Console.WriteLine(rei);
            #endregion

            #region
 
 陣列的序列化
            MemoryStream ms = new MemoryStream();
            BinaryFormatter bf = new BinaryFormatter();
            bf.Serialize(ms, arrI);

            byte[] newArray = new byte[ms.Length];
            ms.Position = 0;
            ms.Read(newArray, 0, newArray.Length);
            ms.Close();

            // 反序列化
            MemoryStream memo = new MemoryStream(newArray);
            bf.Deserialize(memo);
            #endregion

            #region 類的序列化
            Person man = new Person();
            man.name = "David";
            man.sex = "male";
            man.age = 21;

            //序列化
            MemoryStream ms01 = new MemoryStream();
            BinaryFormatter bf01 = new BinaryFormatter();
            bf01.Serialize(ms01, man);
            byte[] arr01 = new byte[ms01.Length];
            ms01.Position = 0;
            ms01.Read(arr01, 0, arr01.Length);
            ms01.Close();

            //解序列化
            MemoryStream ms001 = new MemoryStream(arr01);
            BinaryFormatter bf001 = new BinaryFormatter();
            Person newMan =  (Person)bf001.Deserialize(ms001);

            #endregion

            #region 類的json序列化
            Console.WriteLine(man.say());
            string srMan = JsonConvert.SerializeObject(man);
            Console.WriteLine(srMan);

            //json反序列化
            Person newaMan = JsonConvert.DeserializeObject<Person>(srMan);
            newaMan.say(); //序列化再反序列化之後man變啞了

            #endregion

            Console.ReadKey();
        }
    }
}

用到的Person類的定義是

using System;

namespace Test1
{
    [Serializable]
    class Person
    {
        public string name;
        public string sex;
        public int age;
        public string say()
        {
            return "hello,world";
        }

    }
}
