custom config xml setting and storing into dictionary object

I plan to set up configuration keys for FormFields, QueryString parameters etc. In my web.config I have setting as follows:

<WhiteListPaametersGroup>
   <WhiteListPaameters>
     <FormField1>EVENTVALIDATION</FormField1>
     <FormField2>VIEWSTATE</FormField2>
     <FormField3>Button1</FormField3>
 
     <QueryString1>firstname</QueryString1>
     <QueryString2>lastname</QueryString2>
 
   </WhiteListPaameters>
 </WhiteListPaametersGroup>
 

Then in my code, I read the value as follows:

Dictionary<string, string> parameters = new Dictionary<string,string>();
 
 foreach (XmlNode n in section.ChildNodes)
 {
     parameters.Add(n.Name, n.InnerText);
 }
 

Is there a better way of storing this. Later on, I want to be able to go through dictionary like object, and be able to get settings for FormFields, Querystrings etc.

Please let me know if I could write it cleaner.

Thanks
