I have an array called _updatedComponents of objects that are of class NetworkComponent. I have to serialize it in the way that the name and namespace of the root element (=array) is changed and individual NetworkComponent-item's name is changed to component. I have a code below that causes an exception:
System.InvalidOperationException: There was an error reflecting type 'ComponentSyncService.NetworkComponent[]'. —> System.InvalidOperationException: XmlRoot and XmlType attributes may not be specified for the type ComponentSyncService.NetworkComponent[].
Code:
XmlAttributeOverrides xaos = new XmlAttributeOverrides();
// the array itself aka the root. change name and namespace
XmlElementAttribute xea = new XmlElementAttribute(_updatedComponents.GetType());
xea.Namespace = "http://www.example.com/nis/componentsync";
xea.ElementName = "components";
XmlAttributes xas = new XmlAttributes();
xas.XmlElements.Add(xea);
xaos.Add(_updatedComponents.GetType(), xas);
// then the items of the array. just change the name
xea = new XmlElementAttribute(typeof(networkcomponent));
xea.ElementName = "component";
xas = new XmlAttributes();
xas.XmlElements.Add(xea);
xaos.Add(typeof(NetworkComponent), "NetworkComponent", xas);
XmlSerializer serializer = new XmlSerializer(_updatedComponents.GetType(), xaos);
XmlTextWriter writer = new XmlTextWriter(string.Format("{0}\\ComponentSyncWS_{1}.xml",
Preferences.FileSyncDirectory, requestId), Encoding.UTF8);
serializer.Serialize(writer, _updatedComponents);

What is
_updatedComponents
? I'm guessing it is aNetworkComponent[]
- which will make things very tricky. I would suggest writing a wrapper type:Then you can associate the correct attributes. If you need to support ad-hoc attributes on
NetworkComponent
you'd still need to use attribute-overrides (hence I haven't decorated the above at all), butComponentsMessage
should be happy to take the attributes.Alternately, just write a separate DTO and map the values.
If it is simple, you might just be able to use:
Alternatively, if you must use attribute-overrides, I'd still use a wrapper object:
