Question

我在ASP.NET MVC3项目中使用Fluent NHibernate。我正在编写自定义成员资格提供程序并设置了FNHRoleProvider类。其中一部分包含以下try catch blocK：

private Entities.Roles GetRole(string rolename)
{
    Entities.Roles role = null;
    using (ISession session = SessionFactory.OpenSession())
    {
        using (ITransaction transaction = session.BeginTransaction())
        {
            try
            {
                role = session.CreateCriteria(typeof(Entities.Roles))
                    .Add(NHibernate.Criterion.Restrictions.Eq("RoleName", rolename))
                    .Add(NHibernate.Criterion.Restrictions.Eq("ApplicationName", this.ApplicationName))
                    .UniqueResult<Entities.Roles>();

                //just to lazy init the collection, otherwise get the error 
                //NHibernate.LazyInitializationException: failed to lazily initialize a collection, no session or session was closed
                IList<Entities.Users> us =  role.UsersInRole; 
            }
            catch (Exception e)
            {
                if (WriteExceptionsToEventLog)
                    WriteToEventLog(e, "GetRole");
                else
                    throw e;
            }
        }
    }
    return role;
}

我收到一条错误，指出当前命名空间中不存在Criterion，尽管事实上我已经将NHibernate.Criterion添加到了我的using语句中。我还能够在对象浏览器中查看命名空间的这一部分。

如何解决构建错误？

我怀疑您将命名空间命名为NHibernate，因此最好在NHibernate.Criterion.之前移除Restrictions

使用NHibernate.Criterion.Restriction时找不到命名空间
