Question

我是c＃的新手，我有一些要求我需要读取以下App.config文件的值。

要求1。在配置节点中，我需要计算ArchivePath节点的数量并循环他们每个人。假设我需要遍历第一个ArchivePath节点，需要访问Email，Name和SSN的值。就像我需要遍历所有这些值一样。

2.我还需要访问Key LocationName并从节点获取值。

我真的不是那么多c＃专家，我使用.net 4.0

<configuration>
  <Config>
    <ArchivePath Email="Y" Name="ClientName" SSN="123455678"/>
    <ArchivePath Email="Y" Name="ClientName1" SSN="123455678"/>
    <ArchivePath Email="Y" Name="ClientName2" SSN="123455678"/>
    </Config>

  <appSettings>
    <!--all times in seconds-->
    <add key="LocationName" value="India" />

  </appSettings>

</configuration>

先谢谢。

我尝试了以下链接中的代码 http://blog.danskingdom.com/adding-and-accessing-custom-sections-in-your-c-app-config/

我从下面的课程收到错误，代码中是否缺少任何内容
