父類是
BLOject
裡面有
Key和EditState屬性
子類PrintSheet,PrintSheetPart都同時繼續左抽像類BLOject
AddDataWithMark(PrintSheet.parts, PrintSheetPart);
如果BLobject是接口，所有實現了此接口的類會用Add方法後都會成功把PrintSheetPart加入PrintSheet
但如果BLOject是抽像類，當調用添加更改方法時，由於子類轉父類後，雖然Key,EditState都會改變，但再用Add方法把PrintSheetPart加入PrintSheet是不會加到的。後來使用泛型涵數就可以解決到。
具體如下改變:
