At Serialization in ObjecttoByteArray() exe getting slow

Question

namespace ConsoleApplication2

[Serializable]

};

[Serializable]

struct Cycle_

{

public Int16 A;

public Int16 B;

public Int16 C;

public Int16 D;

public Int32 E;

};

class declaration

{

public List<Cycle_> cycledata = new List<Cycle_>();

public List<DataTypes> idata = new List<DataTypes>();

public byte[] ObjectToByteArray(Object obj)

{

if (obj == null)

return null;

BinaryFormatter bf = new BinaryFormatter();

using (MemoryStream ms = new MemoryStream())

{

bf.Serialize(ms, obj);

return ms.ToArray();

}

}

}

class Program

{

{

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

cycle.A = 40;

cycle.B = 41;

cycle.C = 42;

cycle.D = 43;

cycle.E = 44;

dec.cycledata.Add(cycle);

dec.idata.Add(ion);

}

byte[] arrByte = dec.ObjectToByteArray(dec.cycledata);

byte[] arrByte1 = dec.ObjectToByteArray(dec.idata);

}

}

}

 

 

 

 

In objecttoByteArray Function in declaration class... Serialization will done for converting list to byte array , at that point exe getting slow for some few milliseconds.
