--------------------编程问答-------------------- 上面是最简单的一个简单三层架构 --------------------编程问答-------------------- http://download.csdn.net/source/2623660三层项目实例 --------------------编程问答-------------------- www.51aspx.com有很多例子 --------------------编程问答--------------------
谢谢.
--------------------编程问答-------------------- 下一个动软的三层生成器、还写个毛 头大 。直接生成得了 又不从事什么科研 只要完成功能就行！
补充：.NET技术 , ASP.NET
