How to get an "PART_NUMBER" of routing object?

[fatdogs81]

Hi,

I'm using NX7.5 / Windows 7 pro(X64), C#(.NET Framework 3.5)

I wanna make a program creating automatically partlist.

Component names can be got by below code.
But I don't know how to get routing object's part numbers.

Please refer to attached ppt file and give me some advice.

            IdSymbolCollection idCol = theSession.Parts.Work.Annotations.IdSymbols;
            IdSymbol ids;
            IEnumerator iEnum1 = idCol.GetEnumerator();
[URL unfurl="true"]http://www.eng-tips.com/threadminder.cfm?pid=561[/URL]
            iEnum1.Reset();

            while (iEnum1.MoveNext())
            {
                ids = (IdSymbol)iEnum1.Current;
                IdSymbolBuilder idsb = idCol.CreateIdSymbolBuilder(ids);

                long number = 0;
                bool isNumber = long.TryParse(idsb.UpperText, out number);

                if (idsb.Type.ToString() == "Circle" && isNumber == true && ids.NumberOfAssociativities > 0)
                {
                    listIDSymbolTag.Add(ids.Tag);
                    listIDSymbolNum.Add(idsb.UpperText);

                        Associativity assoc = ids.GetAssociativity(1);
                        NXObject obj = assoc.FirstObject;

                        if (obj.IsOccurrence)
                        {
                            lw.WriteLine("Component Name: " + obj.OwningComponent.Name + "\n");
                        }
                }
            }
