Hi!
I'm trying to serialize an object which contains a collection. this is the
code of the object Persona.

public class Persona
{
...
.
    [XmlAttribute("Nombre")]
    public string Nombre
    {
        get
            {return m_Nombre ;}
        set
            {m_Nombre = value;}
    }

    [XmlElement(typeof(Email))] <-- I don't know what to put here
    public Emails Emails
    {
        get
        {return m_Emails;}
        set
        {m_Emails = value;}
    }
}

The Emails collection is defined like this

public class Emails : IEnumerable, IEnumerator
    {
        private ArrayList m_emails = new ArrayList();
        private int intCurrent = 0;

        public Emails()
        {
            //
            // TODO: Add constructor logic here
            //
        }

        public Email this[int index]
        {
            get
            { return (Email)m_emails[index]; }
        }

        public void Add (Email newEmail)
        {
            m_emails.Add(newEmail);
        }

        public int Count()
        {
            return m_emails.Count;

        }

        public IEnumerator GetEnumerator()
        {
            return (IEnumerator)this;
        }

        public bool MoveNext()
        {
            if (intCurrent < this.Count())
            {
                intCurrent++;
                return true;
            }
            else
            {
                return false;
            }

        }

        public object Current
        {
            get { return m_emails[intCurrent-1]; }
        }

        public void Reset()
        {
            intCurrent = 0;
        }

    }

I want to generate this XML

<Persona Nombre="magoo" Apellido="magoo">
    <Emails>
        <Email mail="Click here to reveal e-mail address" ...>
        <Email mail="Click here to reveal e-mail address" ..>
    </Emails>
</Persona>

I cannot generate the <Emails> section with the <Email> elements inside.

thanks in advance,
Matias

Try the System.Xml.Serialization.XmlArray attribute.

thanks Ryan,
I finally solved using the XmlArrayItem attribte to specify the type of the
class in the collection.

[XmlArrayItem("Email", typeof(Email))]
public Emails Emails
{...
