Answer 1

最主要的问题是CObList 中的元素还是CObList怎么才能得到第二个CObList中的元素f_name;

Answer 2

 POSITION p=allOpinion.GetHeadPosition();
    while(p!=NULL)
    {
        CObList *plist=allOpinion.GetNext(p);         POSITION p1=plist.GetHeadPosition();
         while(p1!=NULL)
         {
            Feature* fea=(Feature*)plist.GetNext(p1);          
          }
    }

Answer 3

不行啊POSITION p=allOpinion.GetHeadPosition();
    while(p!=NULL)
    {
        CObList *plist=allOpinion.GetNext(p);// error C2440: “初始化”: 无法“CObject *”转换为“CObList *”         POSITION p1=plist->GetHeadPosition();
         while(p1!=NULL)
         {
            Feature* fea=(Feature*)plist->GetNext(p1);          
          }
    }

Answer 4

强行转换了
你也可以用vector或者CTypedPtrList
