使用工作模式的单位，你不把所有的数据访问方法，工作独立的单元。您可以使用工作单位周围需要做的，这是在大多数情况下，在Web应用程序中的WebRequest整部作品。这个想法是，一​​个请求可能失败，或成功。当一个请求过程中添加2项数据库中，既要增加，还是不行。不只是其中之一。在大多数情况下，最简单的方法在MVC开始工作单位（或其他网络）的应用是在Global.asax

With the unit of work pattern, you don't put every dataaccess method in a separate unit of work. You use the unit of work around the whole work that needs to be done, which is in most cases in a web application a webrequest. The idea is that a request can fail, or succeed. When you add 2 items to the database during one request, the should be both added, or not. Not just one of them. In most cases, the easiest way to start a unit of work in a mvc (or other web) application is in the begin and end request methods of the global.asax

class Global
{
    BeginRequest()
    {
        servicelocater.get<unitofwork>().start();
    }

    EndRequest()
    {
        var unit = servicelocater.Get<Unitofwork>();
        try
        {
            unit.commit();
        }
        catch
        {
            unit.rollback();
            throw;
        }
    }
}

class Repository<T>
{
     public Repository(INHibernateUnitofwork unitofwork)
     {
         this.unitofwork = unitofwork;
     }

     public void Add(T entity)
     {
         unitofwork.session.save(entity);
     }
}
