方法一：利用CATIDescendants 接口
3 p8 L) o& f! p- ]$ N# l+ oCATIDescendants_var spDescendantsOnPart = spPrtPart;
& `! G5 d  C; L  p5 }. ^4 `. Q& KCATListValCATISpecObject_var spSpecObjects;
9 N2 {0 d6 u' H' g4 ~; ypiDescendantsOnPart->GetAllChildren("CATICkeParm", spSpecObjects);
! H. ?2 X9 U/ E+ q; Z" x0 J, [方法二：利用CATIParmPublisher 中接口
CATIParmPublisher_var spParmPublisher = spPrtPart;
3 k* T+ K5 t  M% LCATListValCATISpecObject_var ListFound;
spParmPublisher->GetAllChildren("CATICkeParm",ListFound);
方法三：利用CATContainer 中的ListMembersHere 方法
SEQUENCE(CATBaseUnknown_ptr) ListObj;
" \$ j  t1 I) a8 H! |4 Rlong NbObj = spContainer ->ListMembersHere("CATICkeParm",ListObj);
for(int j=0;j<NbObj;j++)//注意从0 开始
{
CATIAlias_var spAlias = ListObj[j];
2 S3 S: l0 s, s7 z$ Qcout<<spAlias->GetAlias()<<endl; //输出参数的名字
}
