I'm glad that worked. Hope you're not working all weekend long. :)

>>Hi Keith,

>>You need to set the memory stream position back to 0 before you attempt to deserialize. The problem is that the position is still sitting at the end.

>>>I'm getting an error - "The root element is missing." when attempting to deserialize from a memory stream into an object. What is driving me nuts is that I tested by saving the stream to a file right before serializing the object, and then saving the stream to a different file right before deserializing, and the files look structurally identical to me.

>>>The serialized file:
>>>
>>>  <?xml version="1.0" ?>
>>>- <ArrayOfTicketPurchaseItem xmlns:xsd="http://www.w3.org/2001/XMLSchema"
>>> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
>>>- <TicketPurchaseItem>
>>>- <EventItem>
>>>  <Key>7</Key>
>>>  <Value>High Holy Days (all services)</Value>
>>>  </EventItem>

>>>  <AdultQuantity>2</AdultQuantity>
