C＃：从自定义.config文件获取值

Question

I'd like to get a value from this config file from within an MVC view. How is this achieved?

Thanks

UnsupportedBrowsers.config (projectRoot/config/..)

<UnsupportedBrowsers>
  <Browser alias="Internet Explorer">
    <Version>
      <add key="ie6" value="IE6"/>
      <add key="ie7" value="IE7"/>
      <add key="ie8" value="IE8"/>
    </Version>
  </Browser>
</UnsupportedBrowsers>

Answer 1

First, it would be better to do it in the Controller rather than in the View.

Second, reading an XML file is an easy task, use XDocument class for example:

var xDoc = XDocument.Load("projectRoot\config\UnsupportedBrowsers.config");
var versionKeys = xDoc.Descendants("Version").First().Descendants();

foreach(var key in versionKeys)
{
  //Do something with the retrived keys..
}

Side note:

In any case, you're better cache this object in order to avoid of I/O blockings if each new incoming request need to use it.
