Updated: Read this Article and download source code, it may help you to read/write new section in config files.

To read the AppSettings from the Web.Config file you can use the ConfigurationSettings or ConfigurationManager Class.

It works like the following

string connectionInfo = ConfigurationSettings.AppSettings["ConnectionInfo"]; 

ConnectionInfo is in the Web.config file under the AppSettings like

<appSettings>
<add key="ConnectionInfo" value="server=(local);database=Northwind;Integrated Security=SSPI" />
</appSettings>

and to write in the web.config AppSettings section.. Let’s say you have a key ‘SiteName’ in your appsettings section of your config file… you can update it like that..

Configuration config = WebConfigurationManager.OpenWebConfiguration("~");  
config.AppSettings.Settings["SiteName"].Value = "New Site Name Value";  
config.Save(ConfigurationSaveMode.Modified);  
ConfigurationManager.RefreshSection("appSettings");
