[ARX函数]：我想遍历数据库的线型表,编译出错误

baronnnd

void SetHLineType(AcDbObject *pobj,char *linetypename)
{
        //遍历线型表
        AcDbLinetypeTable *pLtable;
        AcDbLinetypeTableRecord *pLtableRec;
        AcDbObjectId *idobj;
        char linename[50];
        AcDbPolyline *pl;

        if (pobj->isA()==AcDbPolyline::desc()) {
                pl=(AcDbPolyline*)pobj;
        }
        else
        {
                acedAlert("不是多义线!无法设定线性");
                return;
        }
        acdbHostApplicationServices()->workingDatabase()->getSymbolTable(pLtable,AcDb::kForRead);
        AcDbSymbolTableIterator *pLtableIter=new AcDbSymbolTableIterator();               
        for(pLtableIter->start();pLtableIter->done();pLtableIter->step())
        {
                pLtableIter->getRecord(pLtableRec,AcDb::kForRead);
                pLtableRec->getName(linename);                        
                pLtableRec->close();
        }
        pLtable->close();
       
}
错误代码如下
rror C2248: 'AcDbSymbolTableIterator::AcDbSymbolTableIterator' : cannot access protected member declared in class 'AcDbSymbolTableIterator'
我看了定义,AcDbSymbolTableIterator是protect类型 的,请问哪位大虾可以多多指点,谢谢

类型转换和比较不是ARX的标准转换
