EF-Linq将查询结果转换为List<string>

 

 

List<int> id_list = new List<int>() { 1 };//测试数据...

List<string> guid_list = (from uinfo in db.UserInfo
                                          where id_list.Contains(uinfo.ID)
                                          select new
                                          {
                                              uid= uinfo.Guid
                                          }).ToList().Select(u => u.uid).ToList<string>();
