public static void WriteObjectContentInDocument(string path)
{
    // Create the object to serialize.
    Person p = new Person("Lynn", "Tsoflias", 9876);

    // Create the writer object.
    FileStream fs = new FileStream(path, FileMode.Create);
    XmlDictionaryWriter writer =
        XmlDictionaryWriter.CreateTextWriter(fs);

    DataContractSerializer ser =
        new DataContractSerializer(typeof(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();
    fs.Flush();
    fs.Close();
