100分求助。不知道为什么后台。CS文件中的代码不会执行？这两个文件都是照着书上一模一样写下来的，怎么回事？

你们可以自己拷到机子上试一试，后台代码不会执行，只可以生成界面

为什么？框架不难装啊，你原来是用vs.net直接装的吧，单装dotnetfx.exe一会儿就好

原来是。NET框架出了问题，妈的，把IIS重装了一下，。NET框架就没用了，所以网页都不能运行了，我该怎么做呢

如果你的ASPX后台文件是VS.NET项目自动生成的，当然就没问题
如果是自己写的后台文件，方法如上所述

楼上的方法是没有问题，但是如果楼主先编译一下在运行也没有问题的。
Codebehind要先编译一下。

寒～～～～

把
HtmlControlUsage.aspx文件为：
<%@ Page language="c#" Codebehind="HtmlControlUsage.aspx.cs" AutoEventWireup="false" Inherits="systemWebUIHTMLControlsCS.HtmlControlUsage" %>
改为：
HtmlControlUsage.aspx文件为：
<%@ Page language="c#" src="HtmlControlUsage.aspx.cs" AutoEventWireup="false" Inherits="systemWebUIHTMLControlsCS.HtmlControlUsage" %>
