C# ConfigurationManager.GetSection returns null

Last Modified: 2012-07-01
I am trying to get the section in my app.config file.  I'm using ConfigurationManager.GetSection but always get a null value.  Below is my code and app.config file.

Any ideas?

NameValueCollection nvc = (NameValueCollection)ConfigurationManager.GetSection("groupInfo/sectionInfo1");
if (nvc != null)
    for (int i = 0; i < nvc.Count; i++)
        Console.WriteLine(nvc[i] + " = " + nvc.Keys[i]);

<?xml version="1.0" encoding="utf-8" ?>

        <sectionGroup name="groupInfo">
            <section name="sectionInfo1" type="System.Configuration.NameValueSectionHandler"/>
            <section name="sectionInfo2" type="System.Configuration.NameValueSectionHandler"/>

            <add key="myKeyA" value="AAA"/>
            <add key="myKeyB" value="BBB"/>
