好了，截止到这里，我们基本上可以说是公德圆满了！大家可以休息休息了，我们在本章中所讲的内容就是做一个专栏管理的首页，首页应该包括所有的栏目类别，最近的10篇文章和最热门的10篇文章我们现在来看看这个本来第一个写的aspx文件:default.aspx

<script language=vb runat=server>

总结：我们在学习完简单的留言版以后，通过这个稍微复杂和实际的应用，对asp.net 的编程应该说已经基本上熟悉了，现在这个程序在豆腐技术站已经提供下载了。，我们还通过这个程序，对asp.net 的 pagelet 进行了一定的了解和使用，因此通过这写文章，我们已经对asp.net 的编程有了很基础的认识，希望大家趁热打铁，熟悉一下豆腐的例子，也自己做几个程序看看！
