You have to reference the <code>System.Configuration</code> assembly which is in GAC.
Use of <code>ConfigurationManager</code> is not WPF-specific: it is the privileged way to access configuration information for any type of application.
Please see <a href="https://docs.microsoft.com/en-us/dotnet/api/system.configuration.configurationmanager" rel="noreferrer">Microsoft Docs - <code>ConfigurationManager</code> Class</a> for further info.

In your <code>app.config</code>, change your appsetting to:
<pre class="lang-xml prettyprint-override"><code>&lt;applicationSettings&gt;
 &lt;WpfApplication1.Properties.Settings&gt;
 &lt;setting name=&quot;appsetting&quot; serializeAs=&quot;String&quot;&gt;
 &lt;value&gt;c:\testdata.xml&lt;/value&gt;
 &lt;/setting&gt;
 &lt;/WpfApplication1.Properties.Settings&gt;
&lt;/applicationSettings&gt;
</code></pre>
Then, in the code-behind:
<pre class="lang-cs prettyprint-override"><code>string xmlDataDirectory = WpfApplication1.Properties.Settings.Default.appsetting.ToString()
</code></pre>

blocks|key|1355049|text|这也是可行的|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1355050|WpfApplication1.Properties.Settings.Default["appsetting"].ToString()|code-block|syntax|javascript|1355051|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

This also works 

<pre><code>WpfApplication1.Properties.Settings.Default["appsetting"].ToString()

blocks|key|1570239|text|您必须在解决方案中添加对System.configuration的引用。此外，还应包括using+System.Configuration;。完成此操作后，您将可以访问所有配置设置。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1570240|entityMap^0|C|K|17|R|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

You have to add the reference to <code>System.configuration</code> in your solution. Also, include <code>using System.Configuration;</code>. Once you do that, you'll have access to all the configuration settings.

blocks|key|1570279|text|你必须通过浏览器引用System.Configuration+(不仅仅是追加using+System.Configuration)。然后你可以写：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1570280|string+xmlDataDirectory+=+

You have to reference <code>System.Configuration</code> via explorer (not only append <code>using System.Configuration</code>). Then you can write:

<pre><code>string xmlDataDirectory = 
 System.Configuration.ConfigurationManager.AppSettings.Get("xmlDataDirectory");
</code></pre>

Tested with VS2010 (thanks to www.developpez.net).
Hope this helps.

</configuration>|code-block|syntax|javascript|1570365|将System.Configuartion添加到我的项目中。|offset|length|style|CODE|1570366|在顶部的文件中添加using+System.Configuration语句。|1570367|然后使用以下语句：|1570368|string+queuePath+=+ConfigurationManager.AppSettings["POCPublishSubscribeQueueName"].ToString();|1570369|entityMap^0|0|0|0|1|K|0|9|Q|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|X|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|Y|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|Z|8|@$K|10|L|11|M|N]]|9|@]|A|$]]|$1|O|3|P|5|6|7|12|8|@$K|13|L|14|M|N]]|9|@]|A|$]]|$1|Q|3|R|5|6|7|15|8|@]|9|@]|A|$]]|$1|S|3|T|5|F|7|16|8|@]|9|@]|A|$G|H]]|$1|U|3|-4|5|6|7|17|8|@]|9|@]|A|$]]]|V|$]]

In my case, I followed the steps below.
App.config
<pre class="lang-xml prettyprint-override"><code>&lt;configuration&gt; 
 &lt;startup&gt; 
 &lt;supportedRuntime version=&quot;v4.0&quot; sku=&quot;.NETFramework,Version=v4.5&quot; /&gt;
 &lt;/startup&gt;

 &lt;appSettings&gt;
 &lt;add key=&quot;POCPublishSubscribeQueueName&quot; value=&quot;FormatName:Direct=OS:localhost\Private$\POCPublishSubscribe&quot;/&gt;
 &lt;/appSettings&gt;

&lt;/configuration&gt;
</code></pre>
Added <code>System.Configuartion</code> to my project.
Added <code>using System.Configuration</code> statement in file at top.
Then used this statement:
<pre class="lang-cs prettyprint-override"><code>string queuePath = ConfigurationManager.AppSettings[&quot;POCPublishSubscribeQueueName&quot;].ToString();
</code></pre>

blocks|key|1570433|text|我有一个类库WPF项目，我使用：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1570434|'Read+Settings

I have a Class Library WPF Project, and I Use: 



<pre><code>'Read Settings
Dim value as string = My.Settings.my_key
value = "new value"

'Write Settings
My.Settings.my_key = value
My.Settings.Save()
</code></pre>

I created an App.config file in my WPF application:
<pre class="lang-xml prettyprint-override"><code>&lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot; ?&gt;
&lt;configuration&gt;
 &lt;appsettings&gt;
 &lt;add key=&quot;xmlDataDirectory&quot; value=&quot;c:\testdata&quot;/&gt;
 &lt;/appsettings&gt;
&lt;/configuration&gt;
</code></pre>
Then I try to read the value out with this:
<pre class="lang-cs prettyprint-override"><code>string xmlDataDirectory = ConfigurationSettings.AppSettings.Get(&quot;xmlDataDirectory&quot;);
</code></pre>
But it says this is obsolete and that I should use ConfigurationManager which I can't find, even searching in the class view.
Does anyone know how to use config files like this in WPF?
