如何解决错误无法在iis 7中添加具有唯一键属性'value'的类型add的重复集合条目

Question

我创建了一个asp.net网站,并在iis 7中发布.我删除了iis 7中的默认网站选项并在iis 7中创建了新网站.当我单击默认文档时,我收到错误,如"错误无法添加重复"类型为add的集合条目,其唯一键属性'value'设置为index.aspx".我在web.config文件中使用了以下代码.

任何人都可以提供帮助,这意味着它对我的项目非常有用.谢谢..

Answer 1

IIS7在其配置文件中定义了一个defaultDocument部分,可以在%WinDir%\ System32\InetSrv\Config文件夹中找到该部分.最有可能的是,文件index.aspx已经被定义为IIS7的一个配置文件中的默认文档,您将在web.config中再次添加它.

我怀疑删除线 <add value="index.aspx" />

从defaultDocument/files部分将解决您的问题.

配置的defaultDocument部分如下所示:

<defaultDocument>
  <files>
    <remove value="default.aspx" />
    <remove value="index.html" />
    <remove value="iisstart.htm" />
    <remove value="index.htm" />
    <remove value="Default.asp" />
    <remove value="Default.htm" />
  </files>
</defaultDocument>

请注意,index.aspx仍将出现在IIS管理器中站点的默认文档列表中.

Answer 2

理想情况是<add value="default.aspx" />在配置中使应用程序可以部署到任何服务器而无需重新配置.恕我直言我认为IIS中的实现很差.

我们使用以下内容使我们的默认文档设置更加健壮,因此通过使用规范URL更加友好的SEO:

<configuration>
  <system.webServer>
    <defaultDocument>
      <files>
        <remove value="default.aspx" />
        <add value="default.aspx" />
      </files>
    </defaultDocument>
  </system.webServer>
</configuration>

对我们来说工作正常.

Answer 3

你需要的只是一个<clear />标签.这是一个例子:

<configuration>
  <system.webServer>
    <defaultDocument>
      <files>
        <clear />
        <add value="default.aspx" />
      </files>
    </defaultDocument>
  </system.webServer>
</configuration>

Answer 4

删除元素应清除此类错误.这背后的原因是继承的设置.您的应用程序将从其父配置文件和计算机(服务器)配置文件继承一些设置.
您可以在添加标记之前删除带有删除标记的重复项,也可以在上层配置文件中使这些标记不可继承.

Answer 5

只要记住以下几点。

在IIS中，如果您有一个名为Pages的文件夹，其中有多个网站。网站将从父目录的web.config文件继承设置。因此，即使文件夹页面（在本示例中为Pages）不是网站而是包含web.config文件，在其中列出的所有网站也将继承该设置。
