C# 反射调用dll函数，再怎么获取内存数据？

            Assembly asm = Assembly.LoadFile(@"D:\vsproject\CadBatch\CadBatch\libry\acdbmgd.dll");
            Type t1 = asm.GetType("AcDbPlotSettings");

            object oPubClass = Activator.CreateInstance(t1, new object[] { theLayout.ModelType });

            MethodInfo oMethod = t1.GetMethod("getPlotPaperSize", BindingFlags.Instance | BindingFlags.NonPublic);
            Point2d pntop = default(Point2d);
            object result = oMethod.Invoke(oPubClass, new Object[] {&pntop.X, & pntop.Y });
            Type object21 = result.GetType();
            Object object22 = Marshal.PtrToStructure(plotSet.UnmanagedObject, asm.GetType("AcDbPlotSettings"));

要继续反射调用AcDbPlotSettings吧

AcDbPlotSettings 是个internal内部类，反射返回值是指针类型，怎么把object 转换为指针。
