Deserialization Error: The XML element 'name' from namespace '' is already present in the current scope

Question

This is my first time using XML Serialization and this is driving me absolutely nuts after 2 days of trying to troubleshoot this.

I get this error w

Ok - I coded up an example. I took a look at the Facebook API, now here is a FULL working example. Try this:

[XmlRoot("photos_getAlbums_response", Namespace="http://api.facebook.com/1.0/")]
public class GetAlbumsResponse
{
    public GetAlbumsResponse() 
    {    
    }

    [XmlElement("album")]
    public List Albums { get; set; }
}

public class Album
{
    [XmlElement("aid")]
    public long Aid{get;set;}

    [XmlElement("cover_pid")]
    public long CoverPid{get;set;}

    [XmlElement("owner")]
    public long Owner{get;set;}

    [XmlElement("name")]
    public string Name{get;set;}

    [XmlElement("created")]
    public long Created{get;set;}

    [XmlElement("modified")]
    public long Modified{get;set;}

    [XmlElement("description")]
    public string Description{get;set;}

    [XmlElement("location")]
    public string Location{get;set;}

    [XmlElement("link")]
    public string Link{get;set;}

    [XmlElement("size")]
    public int Size{get;set;}

    [XmlElement("visible")]
    public string Visible{get;set;}

    public Album()
    {}
}

class XmlUtils
{
    public static T DeserializeFromXml(string xml)
    {
        T result;
        XmlSerializer ser = new XmlSerializer(typeof(T));
        using (TextReader tr = new StringReader(xml))
        {
            result = (T)ser.Deserialize(tr);
        }
        return result;
    }
}

Now.. with an xml photos_getAlbums_response from the Facebook API,

You can deserialize like this:

 GetAlbumsResponse response = XmlUtils.DeserializeFromXml(xmlResponseString);
