方法一：利用CATIDescendants 接口
0 P7 z# i' [  i$ T6 z/ t( oCATIDescendants_var spDescendantsOnPart = spPrtPart;
7 [3 C. E4 E+ G+ D, G) r7 H/ TCATListValCATISpecObject_var spSpecObjects;
1 n; ]6 p$ s9 g# xpiDescendantsOnPart->GetAllChildren("CATICkeParm", spSpecObjects);
3 _% ^* L9 c5 V% ]9 r方法二：利用CATIParmPublisher 中接口
CATIParmPublisher_var spParmPublisher = spPrtPart;
. U! ?: h9 W6 P0 q$ W! d* cCATListValCATISpecObject_var ListFound;
# S- y2 ]' |2 f3 cspParmPublisher->GetAllChildren("CATICkeParm",ListFound);
8 K" I3 _/ m2 L7 ^& T5 ^方法三：利用CATContainer 中的ListMembersHere 方法
SEQUENCE(CATBaseUnknown_ptr) ListObj;
long NbObj = spContainer ->ListMembersHere("CATICkeParm",ListObj);
for(int j=0;j<NbObj;j++)//注意从0 开始
5 S2 k2 Y. E) Z* b* g$ l  g1 U{
