I have a deserialized xml c# objet.
I need to iterate through the oject to display all items, in this case there’s just one, and display the name, colors and sizes for each item.
The xml:
<?xml version="1.0" encoding="utf-8"?>
<Catalog Name="Example">
<Items>
<Item Name="ExampleItem">
<Colors>
<Color Name="Black" Value="#000" />
<Color Name="White" Value="#FFF" />
</Colors>
<Sizes>
<Size Name="Small" Value="10" />
<Size Name="Medium" Value="20" />
</Sizes>
</Item>
</Items>
</Catalog>

Deserialization code:
System.Xml.Serialization.XmlSerializer xSerializer = new System.Xml.Serialization.XmlSerializer(typeof(Catalog));
TextReader reader = new StreamReader("catalog.xml");
Catalog catalog = (Catalog)xSerializer.Deserialize(reader);
foreach (var item in catalog.Items)
{
}
reader.Close();
When I setp through the code there is one item present in catalog.items, but it is empty, no name, colors or sizes.
Any ideas what I need to do?
Thanks
XSD isn’t perfect – and in this case, it definitely gets it wrong!
In my case, I had code like this:
Those “arrays of arrays” are a typical error you sometimes encounter with XSD. I couldn’t even deserialize your test XML !
Once I changed this to just simple one-dimensional arrays, everything works just fine.
And no, I’m sorry, I don’t know of any switch that would allow you to tell XSD to behave like this all the time – it’s manual “after-the-generation-cleanup-work” that needs to be done here.
