    ' Create the object to serialize.
    Dim p As New Person("Lynn", "Tsoflias", 9876)

    ' Create the writer.
    Dim fs As New FileStream(path, FileMode.Create)
    Dim writer As XmlDictionaryWriter = XmlDictionaryWriter.CreateTextWriter(fs)

    Dim ser As New DataContractSerializer(GetType(Person))

    ' Use the writer to start a document.
    writer.WriteStartDocument(True)
    ' Use the writer to write the root element.
    writer.WriteStartElement("Company")
    ' Use the writer to write an element.
    writer.WriteElementString("Name", "Microsoft")

    ' Use the serializer to write the start,
    ' content, and end data.
    ser.WriteStartObject(writer, p)
    ser.WriteObjectContent(writer, p)
    ser.WriteEndObject(writer)

    ' Use the writer to write the end element and
    ' the end of the document.
    writer.WriteEndElement()
    writer.WriteEndDocument()

    ' Close and release the writer resources.
    writer.Flush()
