1. Serialize side:<br />
DataContractSerializer serial = new DataContractSerializer(Acct.GetType());<br />
using (MemoryStream memoryStream = new MemoryStream())<br />
{<br />
	serial.WriteObject(memoryStream, oAcct);<br />
	btPayload = new byte[memoryStream.Length];<br />
	Array.Copy(memoryStream.GetBuffer(), btPayload, btPayload.Length);<br />
}<br />
                <br />
2. Deserialize side:			<br />
byte[] raw = (byte[]) GetPayload();<br />
serial = new DataContractSerializer(typeof(MyAccount));<br />
using (MemoryStream memoryStream = new MemoryStream(raw))<br />
{<br />
	memoryStream.Seek(0, SeekOrigin.Begin);<br />
	oAcct = (MyAccount) serial.ReadObject(memoryStream);<br />
}<br />
