                            TaxonomyFieldValue taxonomyFieldValue = new TaxonomyFieldValue(taxonomyField);
                            taxonomyFieldValue.TermGuid = term.Id.ToString();
                            taxonomyFieldValue.Label = term.Name;
                            SPListItem item = list.Items.Add();
