How do I deserialize XML namespaces in C# (System.Xml.Serialization)?

Question

I am just putting the finishing touches to my Zthes format deserializer (System.Xml.Serialization) which uses the namespace "dc" in the element "thes". All "term" elements are deserializing fine because they have no namespace but I cannot figure out how to tell the deserializer that the "thes" elements have a namespace.

Here is what I am trying to do (which isn't working) so hopefully someone could give me the proper syntax.

[XmlElement("namespace:someElement")]
public string SomeElement;

Answer 1

Here's a quick sample for you...

[XmlRoot("myObject")]
public class MyObject
{
    [XmlElement("myProp", Namespace = "http://www.whited.us")]
    public string MyProp { get; set; }

    [XmlAttribute("myOther", Namespace = "http://www.whited.us")]
    public string MyOther { get; set; }
}

class Program
{
    static void Main(string[] args)
    {
        var xnames = new XmlSerializerNamespaces();
        xnames.Add("w", "http://www.whited.us");
        var xser = new XmlSerializer(typeof(MyObject));
        using (var ms = new MemoryStream())
        {
            var myObj = new MyObject()
            {
                MyProp = "Hello",
                MyOther = "World"
            };
            xser.Serialize(ms, myObj, xnames);
            var res = Encoding.ASCII.GetString(ms.ToArray());
            /*
                <?xml version="1.0"?>
                <myObject xmlns:w="http://www.whited.us" w:myOther="World">
                  <w:myProp>Hello</w:myProp>
                </myObject>
             */
        }
    }
}

Answer 2

[XmlElement("someElement", Namespace="namespace")]
public string SomeElement;

Addendum: Make sure "namespace" is the full URI of the namespace, not just the prefix.
