Self-referencing loop problems

private string MySerializeObject(Object value)
{
StringWriter sw = new StringWriter(CultureInfo.InvariantCulture);
JsonSerializer jsonSerializer = new JsonSerializer();
jsonSerializer.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;
using (JsonWriter jsonWriter = new JsonWriter(sw))
{
jsonWriter.Formatting = Formatting.Indented;
jsonSerializer.Serialize(jsonWriter, value);
}
return sw.ToString();
}
