[RESOLVED] Serialized XML Classes - InvalidOperationException

I have the following attached class. When I use the following code in a form:

Code:

---

        XmlList myList = new XmlList();
        myList.AddItem(new List("test1","test2"));
        myList.AddItem(new List("test3","test4"));
        myList.AddItem(new List("test5","test6"));

        XmlSerializer s = new XmlSerializer( (typeof(XmlList)) );
        TextWriter w = new StreamWriter( "list.xml" );
        s.Serialize( w, myList );
        w.Close();

        XmlList newList;
        TextReader r = new StreamReader( "list.xml" );
        newList = (XmlList)s.Deserialize( r );
        r.Close();

---

It throws an InvalidOperationException and says: "There was an error reflecting type 'XmlList' " on the highlighted line above.

Any ideas? :(

Well I got it to work fine by removing all of the [XmlRoot] and [XmlAttribute] bits. But I shan't mark this as resolved because I'd stil like to know what was causing the original problem :)

You're not going to be happy ;)

In XmlList.cs:

Code:

---

public class List
{
        [XmlAttribute("item1")] public string Item1;
        [XmlAttribute("item1")] public string Item2;

        public List()
        {
        }

        public List(string Item1, string Item2)
        {
                this.Item1                = Item1;
                this.Item2                = Item2;
        }
}

I've removed the XmlAttribute bits from there too...

Sorry, should've been a little clearer :) The problem was that you had two elements exposed with the same name "item1"; thus no need to remove the XML serialisation attributes, just replace with the following:

Code:

---

[XmlAttribute("item1")] public string Item1;
[XmlAttribute("item2")] public string Item2;

ooooooooooooh Christ almighty you're right. I can't believe I didn't see that. Thank you! :D
