是否可以搜索键的所有值并返回键? [英] is it possible to search through all values of keys and return the key?

问题描述

这是我的web.config:

here's my web.config:

<add key="SiteTitle" value="Breaking News, World News, and Multimedia"/>
    <add key="SiteName" value="New York Times"/>
<add key="somekey" value="somevalue"/>

是否可以搜索所有值以找到世界新闻" 并返回"SiteTitle" ?

推荐答案

我确定可以使用RegEx完成此操作，但是您只需在应用设置中搜索每个KVP的内容即可:(根据您的要求进行了编辑评论)

I'm sure this can be done with a RegEx, but you can just search the contents of each KVP in the app settings: (Edited in response to your comment)

public string GetKeyThatHasMyValue (string Section, string ValueToFind)
{
    string Result = null;
    var Settings = (NameValueCollection)ConfigurationManager.GetSection (Section);
    foreach (string Key in Settings.Keys)
    {
        if (Settings[Key].Contains (ValueToFind))
        {
            Result = Key;
            break;
        }
    }

    return Result;
 }

这也假设您正在使用应用程序设置-否则，请使用Eclyps19的代码来获取您感兴趣的部分，然后使用我的代码进行浏览.

This is also assuming you are using app settings--otherwise use Eclyps19's code to grab the section in which you are interested and then use mine to look through them.
