a1和a2层是垃圾层我想把它清掉可怎么这清不掉，请高人帮我看看下面的代码是否有问题？
  AcDbDatabase *pDb= new AcDbDatabase(Adesk::kFalse);
  if (pDb->readDwgFile("C:\\test2.dwg")!=Acad::eOk)
  {
acutPrintf("\nNot open this dwg");
return;
  }
  AcDbLayerTable *pLayerTable;
  pDb->getSymbolTable(pLayerTable,AcDb::kForWrite);
  AcDbObjectIdArray idArr;
  AcDbObjectId entityId;
  pLayerTable->getAt("a1",entityId);
  idArr.append(entityId);
  pLayerTable->getAt("a2",entityId);
  idArr.append(entityId);
  acutPrintf("\n%d",idArr.length());
  pDb->purge(idArr);
  pDb->save();
  delete pDb;
