Problem serializing to Xml then deserializing

I need to serialize to Xml then at a later time deserialize to one of my classes.

Using this to serialize:

Code:

---

        public void Serialize()
        // serialize Schedule to XML file
        {
            try
            {
                XmlSerializer xs = new XmlSerializer(typeof(MSTSSchedule));
                using (StreamWriter writer = new StreamWriter("c:\\temp\\serialized.xml",true))
                {
                    xs.Serialize(writer, this);
                }

            }
            catch (Exception x)
            {

---

and this to deserialize:

Code:

---

        public MSTSSchedule DeSerialize(XmlDocument doc)
        {
            MSTSSchedule sch = new MSTSSchedule();
            try
            {
                XmlNodeReader reader = new XmlNodeReader(doc.DocumentElement);
                XmlSerializer ser = new XmlSerializer(typeof(MSTSSchedule));
                object obj = ser.Deserialize(reader);
                sch = (MSTSSchedule)obj;
                sch.SetResponse(ResponseCodes.RESP_ACK);
            }
            catch (System.Exception ex)
            {
                sch.SetResponse(ResponseCodes.RESP_NAK);
            }
            return sch;
        }

---

and this to test it all:

Code:

---

            try
            {
                schedToday.Serialize();
                XmlDocument xd = new XmlDocument();
                xd.LoadXml("c:\\temp\\serialized.xml");
                MSTSSchedule test = schedToday.DeSerialize(xd);
            }
            catch (System.Exception ex)
            {

---

I get the "[System.Xml.XmlException] = {"Data at the root level is invalid. Line 1, position 1."}" error.

Xml looks like this:

<?xml version="1.0" encoding="utf-8"?>
<MSTSSchedule xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<m_Schedule>
<MSTSAppointment>

My question - shouldn't I be able to deserialize a Xml document that the .net serializer serialized??

using .Net 3.5sp1

I have never used XmlDocument, XmlReader/Writer to serialize/deserialize classes, and I think that might be the problem ?

Here are a few functions from my Settings class I use:

Code:

---

        private static void InternalSave(Settings settings)
        {
            using (FileStream fs = new FileStream(settingsFile, FileMode.Create, FileAccess.Write))
            {
                XmlSerializer xml = new XmlSerializer(typeof(Settings));
                if (xml != null)
                {
                    xml.Serialize(fs, settings);
                }
                else
                {
                    throw new Exception("InternalSave() : Failed to create XmlSerializer");
                }
            }
        }
        private static void InternalLoad(out Settings settings)
        {
            settings = null;
            if (File.Exists(settingsFile))
            {
                using (FileStream fs = new FileStream(settingsFile, FileMode.Open, FileAccess.Read))
                {
                    XmlSerializer xml = new XmlSerializer(typeof(Settings));
                    if (xml != null)
                    {
                        settings = (Settings)xml.Deserialize(fs);
                    }
                    else
                    {
                        throw new Exception("InternalLoad() : Failed to create XmlSerializer");
                    }
                }
            }
            if (settings == null)
                settings = new Settings();

        }

That did the trick! Thanks much!
