打开/关闭NHibernate会话

SessionFactory.Instance //returns ISessionFactory

using(ISession session = SessionFactory.Instance.OpenSession())
{
    using(ITransaction transaction = session.BeginTransaction())
    {
        //some operation
    }
}

使用存储库类,我基本上执行以下操作(配置使用WebSessionContext):

using(ISession session = SessionFactory.Instance.GetCurrentSession())
{
    using(ITransaction transaction = session.BeginTransaction())
    {
        //some operation
    }
}
