I have some code that serializes an array of objects:

   XmlSerializer serializer = new XmlSerializer(typeof(Purchase[]));
   XmlTextWriter w = new XmlTextWriter("vpurchase.xml", Encoding.UTF8);
   serializer.Serialize(w, purchaseArray);

This gives me something like:

<ArrayOfPurchase>
 <Purchase> . . . </Purchase>
 <Purchase> . . . </Purchase>
</ArrayOfPurchase>

Now if I try to deserialize the file with:

   XmlSerializer serializer = new XmlSerializer(typeof(Purchase));
   XmlTextReader r = new XmlTextReader("vpurchase.xml");
   Purchase [] purchaseArray = (Purchase [])serializer.Deserialize(r);

I get an error. Somehow my theory is that the <ArrayOfPurchase> token is not
being recognized properly in deserialization. How can I get this to work
bidirectionallly?

Thank you.
