Moon.ORM- 4.4 隆重發布,在性能和使用便捷上一挑群雄(mysoft,cyq,pdf)

本文轉載自查看原文 2012-12-08 17:15 2454 .NET技術研究/ Orm

從性能上講目前沒有性能與moon可比的框架(非純ADO.NET),便捷上除了實體框架,大家自己使用各框架便可知道.不過我挺喜歡PDF的思路,可以幾乎不用反射實現,所以性能很高.在此表示無意戰爭,只是告訴我的那幫Moon.Orm支持者及還不理解ORM的朋友一點性能上看見.

第一部分論性能

4.4對自動編譯方法進行了重構.

例如:

List<North.Orders> list=DBFactory.GetEntitiesH<North.Orders>(OrdersTable.OrderID.BiggerThan(0),"實體所在的程序集");

看代碼.
