In my asp.net application I want to read authorization section of web.config and modify that. For that I am using the below code but I am not getting the values. So have a look at it and let me know if there is any way to read and update authorization section values AuthorizationSection section; my section is like the following

 <authorization>
       <deny users="?"/>
 </authorization>

And this is the code:

configuration = WebConfigurationManager.OpenWebConfiguration("~");
section = (AuthorizationSection)configuration.GetSection("system.web/authorization"); 
SectionInformation sc= section.SectionInformation;

Thanks, Hima.
