谁知道我错在哪了？

            for (i = strCode.GetLowerBound(0); i <= strCode.GetUpperBound(0); i++)

                ssset=acdDoc.SelectionSets.Add("Temp");
               
                ssset.Select(AcSelect.acSelectionSetAll, Type.Missing, Type.Missing, pFilterType, pFilterData);
                if (ssset != null)
                {
                    if (ssset.Count>0)
                    {
                        ssset.Erase();
                    }
                    ssset.Clear();
                    ssset.Delete();
                }
            }
        }
这段代码在运行过程中，有一部分可以删除，有一部分删除不了，为什么？利用扩展数据选择时，过滤条件这样定义有问题吗？

1000组码只有优化多段线才有效

roamer2000

Polyline、LWpolyline不可以用吗？

雪山飞狐_lzh

LWpolyline（优化）应该是可以的

不过，扩展数据，应该用1001码做过滤器
