XML Recursive Deserialization

Question

I have some XML that I am trying to deserialize. The Kronos_WCF object deserializes fine but the Response objects do not. Is there some recursive deserialization teqnique I am missing?

Here is the XML I am trying to deserialize:

<?xml version='1.0' encoding='UTF-8' ?>
<Kronos_WFC Version="1.0" WFCVersion="6.2.0.4" TimeStamp="6/15/2011 9:15AM GMT-04:00">
<Response Status="Success" Timeout="1800" PersonKey="-1" Object="System" UserName="User" Action="Logon" PersonNumber="User">
</Response>
<Response Status="Success" Object="System" UserName="User" Action="Logoff">
</Response>
</Kronos_WFC>

Here is my deserializer:

public static T Deserialize<T>(this string xml)
{
    var ser = new XmlSerializer(typeof (T));
    object obj;
    using (var stringReader = new StringReader(xml))
    {
        using (var xmlReader = new XmlTextReader(stringReader))
        {
            obj = ser.Deserialize(xmlReader);
        }
    }
    return (T) obj;
}

Here is a screen shot of what I am seeing in VS2010:

Here is the code from the classes generated using XSD.exe:

Any help would be appreciated.

It would help if you can post the code for `Kronos_WFC` class. — Bala R, Jun 15 '11 at 13:38
Not directly related, but you should not be using `new XmlTextReader()`. It's been deprecated since .NET 2.0. Use `XmlReader.Create()` instead. — John Saunders, Jun 15 '11 at 14:06

The Response attributes from the xml does not seem to match those present in your class.

I noticed that myself but wouldn't it populate the ones it does find? – Cyberdrew Jun 15 '11 at 14:04

Status defined in Response has the wrong Attribute

it should be

[XmlAttributeAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
public string Status

and instead it is actually

[XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]

so the xml deserializer is looking for

<Response><Status>Success</Status></Response>

This will at least allow you to deserialize Response.Status

It doesnt look like that xml snippet matches with the class definition.

I generated this from an XSD supplied by the API vendor. Is there a way to set this when generating the classes using XSD.exe or does it need to just be manually changed? Thanks. – Cyberdrew Jun 15 '11 at 14:42

If the xsd is from a vendor and the xml response is from the same vendor's product, I'd talk to the vendor about it. – Bala R Jun 15 '11 at 14:44

@Cyberdrew re: XSD I do not know. Instead, i would modify the supplied XSD to match the xml you're receiving so the correct classes *are* generated. I would also ask the vendor why there is a mismatch in the XSD and the sample xml. – wal Jun 15 '11 at 14:45
Thanks, will do. Thanks for the help. Pardon me being blunt but the API for this product is crap. – Cyberdrew Jun 15 '11 at 14:55
