如何在装配体中找到零部件的配合实体的名称？

也就是说，如果一个零部件在装配体中使用了两次，并且有两个重合配合使用（所述零部件的）同一个面与另一个零部件，我可以提取两个配合的相同名称吗？例如，如果有两个立方体 C1 和 C2，并且每个立方体的一侧与另一侧有一个配对。我们能得到一个伙伴的名字，比如 C1:Ida 和 C2:Idb 来识别立方体的一边吗？

这里给出了一个类似的问题：https ://forum.solidworks.com/thread/59399并且提供的建议解决方案是

MateEntity2::Reference->MateReference::Name
MateEntity2::Reference→MateReference::ReferenceEntity2→ModelDoc2::GetEntityName

我一直无法找到正确的调用顺序来获得这个。

此外，使用 Solidworks API 中给出的示例，示例https://help.solidworks.com/2021/English/api/sldworksapi/Get_Mate_Reference_Properties_Example_Csharp.htm似乎表明我们想要一个MateReference但我无法正确投射从 aMateEntity.Reference到任何可用的类型。

下面的一些代码提供了一个可重现的示例（在solidworks 21 中），其中许多尝试从aMateEntity.Reference转换为另一种类型都失败了。感谢您的任何指示。

            Mate2 swMate = default(Mate2);
            Feature swFeat = default;
            Feature swMateFeat = null;

            // Iterates through the FeatureManager design tree to find Mates
            swFeat = (Feature)swModel.FirstFeature();
            while ((swFeat != null))
            {
                if ("MateGroup" == swFeat.GetTypeName())
                {
                    swMateFeat = (Feature)swFeat;
                    break;
                }
                swFeat = (Feature)swFeat.GetNextFeature();
            }

            // grab first mate entity : can get parameters etc
            swSubFeat = (Feature)swMateFeat.GetFirstSubFeature();
            swMate = (Mate2)swSubFeat.GetSpecificFeature2();
            swMateEnt = swMate.MateEntity(0);

            // But how is this object used?
