How to find the ID of an AcDbMLeaderStyle object?

[zhengyunyang2019]

How can I find all MLeader style objects?

I have multiple MLeader style objects created in my CAD, and I need to use one of them.

I should find its ID first, but I don't know which interface to use.

AcDbDatabase *pCurDb = acdbCurDwg();
if (pCurDb) 
{
	AcDbDictionary *pStyleDict = nullptr;
	if (pCurDb->getMLeaderStyleDictionary(pStyleDict, AcDb::kForRead) == Acad::eOk) 
	{
		AcDbDictionaryIterator *pIter = pStyleDict->newIterator();
		for (; !pIter->done(); pIter->next()) 
		{
			AcDbObjectId styleId = pIter->objectId();
			AcDbObject *pObj;
			if (acdbOpenAcDbObject(pObj, styleId, AcDb::kForRead) == Acad::eOk) 
			{
				AcDbMLeaderStyle *pLeaderStyle = AcDbMLeaderStyle::cast(pObj);
				if (pLeaderStyle) 
				{
					
				}
				pObj->close();
			}
		}
		delete pIter;
		pStyleDict->close();
	}
}
