How to write List<int> items into an xml file?

Question

I need to write items in the List<int> myList into an xml file. The way the xml file should look like is if the values in the list are 1, 2 and 3. I know this is possible using linq. I want to avoid the serializer options.

<List>
  <itemValue>1</itemValue>
  <itemValue>2</itemValue>
  <itemValue>3</itemValue>
</List>

Answer 1

private static void ToXml(List<int> list)
{
    var doc = new XDocument(new XElement("List", list.Select(x =>
                          new XElement("itemValue", x))));
    doc.Save("test.xml");
}
