How to use ConfigurationManager.AppSettings with a custom section?

.net, appsettings, c#, wpf

Solution

I think you need to get the config section, and access that:

var section = ConfigurationManager.GetSection("server") as NameValueCollection;
var value = section["url"];

And you also need to update your config file:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <configSections>
    <section name="device" type="System.Configuration.NameValueSectionHandler" />
    <section name="server" type="System.Configuration.NameValueSectionHandler" />
  </configSections>
  <device>
    <add key="id" value="1" />
    <add key="description" value="petras room" />
    <add key="location" value="" />
    <add key="mall" value="" />
  </device>
  <server>
    <add key="url" value="http://example.com" />
  </server>
</configuration>

Edit: As CodeCaster mentioned in his answer, `SingleTagSectionHandler` is for internal use only. I think `NameValueSectionHandler` is the preferred way to define config sections.

Problem

I need to get "http://example.com" from using App.config file. But at the moment I am using: ``` string peopleXMLPath = ConfigurationManager.AppSettings["server"]; ``` I cannot get the value. Could you point out what I am doing wrong? ``` <?xml version="1.0" encoding="UTF-8"?> <configuration> <configSections> <section name="device" type="System.Configuration.SingleTagSectionHandler" /> <section name="server" type="System.Configuration.SingleTagSectionHandler" /> </configSections> <device id="1" description="petras room" location="" mall="" /> <server url="http://example.com" /> </configuration> ```
