AppSettings get value from .config file

I'm not able to access values in configuration file.

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
var clientsFilePath = config.AppSettings.Settings["ClientsFilePath"].Value;
// the second line gets a NullReferenceException


.config file:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<!-- ... -->
<add key="ClientsFilePath" value="filepath"/>
<!-- ... -->
</appSettings>
</configuration>


Do you have any suggestion what should I do?

Answer

This works for me:

string value = System.Configuration.ConfigurationManager.AppSettings[key];
