NHibernate Demo 和 效率测试

本文关于NHibernate的Demo和效率测试，希望对大家有用.

1.先去官网下载Nhibernate

2.放入到项目中并建立Helper类

 private static ISession _Session = null;

        public static ISession Session
        {
            get
            {
                if (_Session == null)
                {

                    Configuration cfg = new Configuration();

                    // _Session session factory from configuration object
                    _Session = cfg.Configure(CurrentLocation + "Nhibernate.config").BuildSessionFactory().OpenSession();
                }

                return _Session;
            }
        }

写操作方法

更新

public static string SaveOrUpdate<T>(T item)
        {
            Helper.Session.Clear();
            string msg = string.Empty;
            try
            {
                using (Helper.Session.BeginTransaction())
                {
                    Helper.Session.SaveOrUpdate(item);
                    Helper.Session.Transaction.Commit();
                }
            }
            catch (Exception ex)
            {
                throw ex;
            }

            return msg;
        }

                }
            }
            catch (Exception ex)
            {
                throw ex;
            }

            return msg;
        }

3.建立单元测试项目

略

最后，我知道没有代码你们是不会来的，so，如下 ：

Ps：请用VS2013及以后版本打开
