Question

I’m trying to Serialize some Object, that contain an IList with Children Elements. The IListis non-generic and i cannot just make it at generic one.
I get the exception like “The Type MyObjectChild was not expected. …” and it says something about XMLInclude, but i don’t think thats what I’m searching.
Does anyone have any idea how bring XMLSerialzer to serialize the child elements as well?
Both Elements are [Serializable]

XmlSerializer xmlSerializer = new XmlSerializer(typeof ObservableCollection<MyEntryViewItem>));
FileStream fileStream = new FileStream(exportPath, FileMode.Create);

xmlSerializer.Serialize(fileStream, _listEntries);

public IList ElementChildren { get { return _item.Children; } set { _item.Children = value; RaisePropertyChanged(() => ElementChildren); } }

[Serializable]
public sealed class ElementChild
{
    private int _id;
    private string _text;
    private string _path;
    ...
}

According to Simon Hewitt you can just use the XmlInclude to specify the type of your list. An alternative can be found at roboxman.wordpress.com
