XmlSerialization Questoin

I have a class that contains several string and integer fields. I can serialize this fine using XmlSerializer.
Now I've added an object array as a field to my class (the object being a user defined class)
My question is how can i have the parent class serialize the object array as well?

here's a dummy example. Pretend like i can serialize an instance of the Settings class, except it won't serialize the ItemData[] array inside it. How can i serialize ItemData[] as well

Code:

---

    [System.Xml.Serialization.XmlTypeAttribute(Namespace =
    "urn:xmlns:CrReport:settings")]
    [System.Xml.Serialization.XmlRootAttribute("settings",
    Namespace = "urn:xmlns:app:settings", IsNullable = false)]
Class Settings
{
public string filename;
public int count;

//How can i have it serialize this as well?
public ItemData[] items;
}

class ItemData
{
public string title
public int size;
}

I haven't really delved into the specifics of serialisation too much but I think you'll find that you'd need to at least decorate the ItemData class with the Serializable attribute and, perhaps, the Items property too.

This worked for me:

Code:

---

[System.Xml.Serialization.XmlTypeAttribute(Namespace =
"urn:xmlns:CrReport:settings")]
[System.Xml.Serialization.XmlRootAttribute("settings",
Namespace = "urn:xmlns:app:settings", IsNullable = false)]
public class Settings
{
    public string filename;
    public int count;

    //How can i have it serialize this as well?
    public ItemData[] items;
}

public class ItemData
{
    public string title;
    public int size;
}

... In some test harness...

            Settings set = new Settings();
            set.count = 5;
            set.filename = "fds";
            set.items = new ItemData[2];
            set.items[0] = new ItemData();
            set.items[0].size = 3;
            set.items[0].title = "test";
            set.items[1] = new ItemData();
            set.items[1].title = "test2";

            string xml = Serialize<Settings>(set);

... Serialize<T> method: ...


        private string Serialize<T>(T entity)
        {
            StringBuilder outputXml = new StringBuilder();

            XmlSerializer ser = new XmlSerializer(typeof(T));
            using (TextWriter stream = new StringWriter(outputXml))
            {
                ser.Serialize(stream, entity);
            }

            return outputXml.ToString();
        }

---

This was the result:

Code:

---

<?xml version="1.0" encoding="utf-16"?>
<settings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="urn:xmlns:app:settings">
  <filename xmlns="urn:xmlns:CrReport:settings">fds</filename>
  <count xmlns="urn:xmlns:CrReport:settings">5</count>
  <items xmlns="urn:xmlns:CrReport:settings">
    <ItemData>
      <title>test</title>
      <size>3</size>
    </ItemData>
    <ItemData>
      <title>test2</title>
      <size>0</size>
    </ItemData>
  </items>
</settings>
