    That works:

    class Program
{
    static void Main(string[] args)
    {
        var obj = "bugaga!";
        System.Runtime.Serialization.DataContractSerializer ser = new System.Runtime.Serialization.DataContractSerializer(obj.GetType());
        MemoryStream ms = new MemoryStream();
        using (XmlWriter xdw = XmlWriter.Create(ms))
        {
            ser.WriteObject(xdw, obj);
        }
        Console.WriteLine(ms.Length);
    }
}

    [update] or just do xdw.Flush(), as already noticed
