Conversion form objecttoBytearray C#

Question

using System;

using System.IO;

using System.Threading;

using System.Collections.Generic;

using System.Runtime.Serialization.Formatters.Binary;

namespace TestApplication

{

/// <summary>

/// data structure

/// </summary>

[Serializable]

struct Data

{

public Int16 A;

public Int16 B;

public Int16 C;

public Int16 D;

public Int32 E;

};

class Converter

{

public List<Data> datas = new List<Data>();

public byte[] ObjectToByteArray(Object obj)

{

if (obj == null) return null;

BinaryFormatter bf = new BinaryFormatter();

using (MemoryStream ms = new MemoryStream())

{

//below function takes few seconds

bf.Serialize(ms, obj);

return ms.ToArray();

}

}

}

class MainProgram

{

static void Main(string[] args)

{

Thread ConvereterThread = new Thread(new ThreadStart(ConvertThread));

ConvereterThread.Start();

}

static void ConvertThread()

{

Converter converter = new Converter();

Data data;

for (int i = 0; i < 1000000; i++)

{

data.A = 40;

data.B = 41;

data.C = 42;

data.D = 43;

data.E = 44;

converter.datas.Add(data);

}

byte[] arrByte = converter.ObjectToByteArray(converter.datas);

}

}

}

 

 

In the above program, still i am using objecttobytearray conversion in thread also  it will be slow(ie Exe is hang for few seconds)
