Xml Serialization

Question

Hi There,

I'm not sure which forum is best for my query, so forgive me if this does not belong here.
I'm trying to learn how to use the various XML attributes for XML serialization. I've started with the [XmlAnyElement] attribute.
The example in the documentation is as follows:

 public class XClass
{
    /* Apply the XmlAnyElementAttribute to a field returning an array
    of XmlElement objects. */
    [XmlAnyElement]
    public XmlElement[] AllElements;
}

public class Test
{
    public static void Main()
    {
        Test t = new Test();
        t.DeserializeObject("file.xml");

        Console.WriteLine("\nPress any key to quit...");
        Console.Read();
    }

    private void DeserializeObject(string filename)
    {
        // Create an XmlSerializer.
        XmlSerializer mySerializer = new XmlSerializer(typeof(XClass));

        // To read a file, a FileStream is needed.
        FileStream fs = new FileStream(filename, FileMode.Open);

        // Deserialize the class.
        XClass x = (XClass)mySerializer.Deserialize(fs);

        // Read the element names and values.
        foreach (XmlElement xel in x.AllElements)
            Console.WriteLine(xel.LocalName + ": " + xel.Value);
    }
}

It does not matter what XML file I put in the bin/debug folder, I always get the following exception:

System.InvalidOperationException was unhandled

I don't want to do anything tricky, like transform a webservice. I just want to see this wildcard in action. Even if with the most simple of XML files.
 
Does anyone know enough about this to assist me?
Thanks
