I'm trying to write XML and I am quite unsuccessful so far,
I have a very simple application with 1 button and one click handler like
that, does anyone know what's wrong with this few  lines ?
//-----------------------------------
private void button1_Click(object sender, System.EventArgs e)
{
   string file = "test.xml";
   XmlTextWriter xtw = new XmlTextWriter(file, Encoding.UTF8);
   try
   {
       xtw.WriteStartDocument();
       xtw.WriteElementString("Name", "aName");
       xtw.WriteStartElement("Data");
       xtw.WriteElementString("Item", "anItem");
       xtw.WriteElementString("Item", "anItem");
       xtw.WriteElementString("Item", "anItem");
       xtw.WriteEndElement();
       xtw.WriteEndDocument();
   }
   finally { xtw.Close(); }
}

it throws an InvalidOperationExeption() when I try to
WriteStartElement("Data");
