在设置好虚拟目录，和IIS后，在IIS中右击选择“浏览”，出现如下错误：
 

Configuration Error

Parser Error Message: 代码子目录“/Do/App_Code/HTML/”不存在。

Source Error: 

Line 101:      -->
Line 102:      <codeSubDirectories>
Line 103:        <add directoryName="HTML" />
Line 104:        <add directoryName="Survey" />
Line 105:      </codeSubDirectories>
 
 
后来以为是连接字符串的问题，改了以后，谁知出现如下问题：
 
 

Configuration Error

Parser Error Message: “providerName”是一个意外标记。应为空格。 行 24，位置 82。

后来，又改了几次连接字符串，出现了第一问题。后来，我把“默认网站”的主目录直接指向网站文件夹。浏览，居然行了。
