[MSCE C#]如何将2个元素关联起来

Question

我创建了2个元素，elementA和elementB，现在我希望鼠标点击elementA后，我可以根据elementA中的信息获取到elementB并对elementB进行操作，该如何实现呢？

如下所示是c/c++的代码演示，c # 的找了一下没找到，可能是目前还没有封装 
 
void TestAddXAttributePersistentElementPath()
{
	ElementAgenda selectset;
	SelectionSetManager::GetManager().BuildAgenda(selectset);
	if (selectset.GetCount() < 2)
	{
 return;
	}
	EditElementHandle& eeh1 = selectset[0];
	EditElementHandle& eeh2 = selectset[1];
	PersistentElementPath persisElePath(eeh2.GetElementRef());
	XAttributeHandlerId xAttHandlerId(123, 456);
	UInt32 xAttId = 1;
	bvector<byte> sink;
	persisElePath.Store(sink);
	if (SUCCESS == ITxnManager::GetCurrentTxn().AddXAttribute(eeh1.GetElementRef(),
 xAttHandlerId, xAttId, sink.begin(), (UInt32)sink.size()))
	{
 printf("SUCCESS");
	}
}
void TestGetXAttribute()
{
	ElementAgenda selectset;
	SelectionSetManager::GetManager().BuildAgenda(selectset);
	if (selectset.GetCount() < 1)
	{
 return;
	}
	EditElementHandle& eeh1 = selectset[0];
	XAttributeHandlerId xAttHandlerId(123, 456);
	UInt32 xAttId = 1;
	XAttributeHandle xAttHandle(eeh1.GetElementRef(), xAttHandlerId, xAttId);
	byte const* bytes = (byte const*)xAttHandle.PeekData();

	PersistentElementPath persisElePath;
	persisElePath.Load(bytes, 5);
	printf("%d
", persisElePath.EvaluateElement(ACTIVEMODEL).GetElementId());
}
