如何只投影两列并列出它们?(NHiBiNATE)

根据下面的表格结构,您如何仅使用nhibernate来投影x和y?如何列出结果,结果列表的类型是什么?

//Table structure, mapped in the traditional way
FunnyTable { 
             x [int] NOT NULL, 
             y [int] NULL, 
             z [int] NOT NULL
           }

//assume criteria is set somewhere else
ProjectionList list = Projections.ProjectionList()
                                 .Add(Projections.Property("x"))
                                 .Add(Projections.Property("y"));
return criteria.SetProjection(list).List<???>??
