Question

I’m trying to deserialize an object back from it’s XML string using xmlSerializer.Deserialize() but the returned object is always blank (not null, but all the properties are null or 0). I can’t work out what I’m doing wrong and yet I get no errors or exceptions.

string xml = "***my xml is here***";

XmlSerializer ser = new XmlSerializer(typeof(Order));
StringReader stringReader = new StringReader(xml);
XmlTextReader xmlReader = new XmlTextReader(stringReader);
Order order = (Order)ser.Deserialize(xmlReader);
xmlReader.Close();
stringReader.Close();

The source of Order.cs was generated from the XSD using the the xsd.exe tool.

Source of order.cs: http://www.nickgilbert.com/etc/1/Order.txt

Sample order XML: http://www.nickgilbert.com/etc/1/example-order.xml

Answer 1

Your sample XML file (example-order.xml) uses the namespace http://tempuri.org/OrderSchema.xsd but the code generated by XSD (order.cs) defines all of the elements in the namespace http://x-rm.com/wrightcottrell/cataloguecd/.

You’ll need these namespaces to match up in order for serialization to work properly.
