ASP网页设计ASP静态网页实例：表单多文件上传类

楼上说交互性不好，太牵强了吧。在微软提供的一套框架中，利用asp做网站，开发效率高，使用人数少，减少不必要的开销。交互性是互动方式，是有开发人员决定的。静态|上传|网页<%

无法实现跨操作系统的应用。当然这也是微软的理由之一，只有这样才能发挥ASP最佳的能力。可是我却认为正是Windows限制了ASP，ASP的概念本就是为一个能让系统运行于一个大的多样化环境而设计的；

掌握asp的特性而且一定要知道为什么。

如何学好ASP,以前也有人问过,把回答给你转过来看看能否对你有帮助:

代码的可重用性差：由于是面向结构的编程方式，并且混合html，所以可能页面原型修改一点，整个程序都需要修改，更别提代码重用了。

兴趣爱好，那么你无须学编程，申请一个域名和空间，在网上下载一些免费开源的CMS系统，你不用改代码，只须熟悉它们的后台操作，像office一样简单方便，很快就能建一个站点，很多站长都是这样做的

代码逻辑混乱，难于管理：由于ASP是脚本语言混合html编程，所以你很难看清代码的逻辑关系，并且随着程序的复杂性增加，使得代码的管理十分困难，甚至超出一个程序员所能达到的管理能力，从而造成出错或这样那样的问题。

尽管MS自己讲C#内核中更多的象VC，但实际上我还是认为它和Java更象一些吧。首先它是面向对象的编程语言，而不是一种脚本，所以它具有面向对象编程语言的一切特性，比如封装性、继承性、多态性等等，这就解决了刚才谈到的ASP的那些弱点。

虽然ASP也有很多网络教程。但是这些都不系统。都是半路出家，只是从一个例子告诉你怎么用。不会深入讨论，更不会将没有出现在例子里的方法都一一列举出来。
