Question

    private byte[] ObjectToByteArray(Object obj)
    {
        if (obj == null)
            return null;
        BinaryFormatter bf = new BinaryFormatter();
        MemoryStream ms = new MemoryStream();
        bf.Serialize(ms, obj);
        return ms.ToArray();
    }


    private Object ByteArrayToObject(byte[] arrBytes)
    {
        MemoryStream memStream = new MemoryStream();
        BinaryFormatter binForm = new BinaryFormatter();
        memStream.Write(arrBytes, 0, arrBytes.Length);
        memStream.Seek(0, SeekOrigin.Begin);
        Object obj = (Object)binForm.Deserialize(memStream);
        return obj;
    }

i can’t do that process in silverligth, didn’t define “BinaryFormatter” class.

There is no such class as BinaryFormatter nor SoapFormatter for Silverlight, but you can use the DataContractJsonSerializer that is supported in Silverlight.
