代碼生成我本想利用t4模闆，但是由于我們的項目ide版本是vs2008，對于t4的參數傳遞支援還不是很友好，你可能說用appdomain.setdata,或者callcontext.logicalsetdata，但是可惜我們的餓mappingrule是不可序列化的，是以最後我隻得采用了字元串拼接最笨的辦法，為了應對生成政策不同，在這裡我們加入了政策模式來應付，來看看代碼結構吧：
在這裡隻支援對do的二級屬性映射為dto的平面屬性，全部針對imappingrule生成代碼，在這裡為了生成合法的代碼而非表達式，對以前的表達式進行了重新的标準約定，在代碼注釋。以及對上個版本的list轉換進行了多次重載，主要為了滿足dto到do對象的特殊要求，因為我們在領域開發存儲dto的時候都是需要先取出do對象在根據dto在do對象的基礎上進行修改，以便orm領域架構或者uow的跟蹤記錄。
