              ObjectResult<CitySearchResult> search =d.ExecuteStoreQuery<CitySearchResult>("usp_SearchcabResult @city1, @city2", para);
              //List<CitySearchResult> search = (d.ExecuteStoreQuery<CitySearchResult>("usp_SearchcabResult", para)).ToList<CitySearchResult>();
              List<CitySearchResult> searchResult=search.ToList<CitySearchResult>();
