How to read appSettings section in the web.config file?

Question

My XML looks like this and the filename is web.config

<?xml version="1.0"?> <configuration>   <appSettings>        <add key="configFile" value="IIS.config"/>     <add key="RialtoDomain" value="ASNC_AUDITORS"/>       </appSettings>   <system.serviceModel>     ....   </system.serviceModel> </configuration> 

In the code when I read like this

String path = ConfigurationSettings.AppSettings["configFile"]; 

I am getting a null value. No exception is thrown. Is this the right way to do it?

Since you're accessing a web.config you should probably use

using System.Web.Configuration;  WebConfigurationManager.AppSettings["configFile"]
