Clean XML serializing a hierarchical, recursive data structure

Question

public class MenuItem
{
    [XmlAttribute(\"text\")]
    public string Text { get; set; }

    [XmlAttribute(\"isL         


        

Answer 1

Add XmlArrayItemAttribute and take away the IsNullable:

[XmlArray("items"), XmlArrayItem("menuItem")]
public List<MenuItem> Items { get; set; }

To get rid of the extra namespaces, you need to use XmlSerializerNamespaces:

var ns = new XmlSerializerNamespaces();
ns.Add("","");
var ser = new XmlSerializer(typeof (MenuItem));
ser.Serialize(Console.Out, obj, ns);
