Deserialize xml to object.

[bhu]

I have a xml which is like this.
now if i remove the iu part from the xml then i am able to deserialize but i
don't want to do it,
any idea how to do it ?

XML:
<iu:InventoryUp dateBatch
xmlns:iu="http://www.abc.com/schema/InventoryUpdate "
xmlns:th="http://www.abc.com/schema/TransactionHead er"
xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance">
<InventoryUpdat e>
<TransactionHea der</TransactionHead er>
</InventoryUpdate >
</iu:InventoryUpd ateBatch>

Code:
public class InventoryUpdate Batch
{
[System.Xml.Seri alization.XmlEl ementAttribute( "InventoryUpdat e")]
public InventoryUpdate[] InventoryUpdate type;
}

InventoryUpdate Batch invtype = new InventoryUpdate Batch();
System.Xml.Seri alization.XmlSe rializer serializer = new
System.Xml.Seri alization.XmlSe rializer(invtyp e.GetType());
System.IO.Strea mReader w = new StreamReader(@" C:\b.xml");
invtype = (InventoryUpdat eBatch)serializ er.Deserialize( w);

thanks
