I have a bunch of key in AppSettings section of my web.config file. I want to read the key and values of those app settings using XML reader technique and populate them in the list box.

    You could do that, but it would be easier to simply use a configuration manager and iterate through all the app settings keys. Or use a Properties file and have them all located in a class. – Justin Oct 05 '10 at 22:22

The best way is to retrive webconfig values is to use System.Configuration.ConfigurationManager.AppSettings;

To retrive values of webconfig from xml reader:

private void loadConfig()
        {

            XmlDocument xdoc = new XmlDocument();
            xdoc.Load( Server.MapPath("~/") + "web.config");
            XmlNode  xnodes = xdoc.SelectSingleNode ("/configuration/appSettings");

                foreach (XmlNode xnn in xnodes .ChildNodes)
                {
                    ListBox1.Items.Add(xnn.Attributes[0].Value  + " = " + xnn.Attributes[1].Value );
                }              

        }

  • This way is better than ConfigurationManager.AppSettings because you can have whatever file name and path that you want. – Paul McCarthy Jun 20 '17 at 10:37

You can just get a reference to the AppSettings NameValueCollection and iterate as follows:

NameValueCollection settings = System.Configuration.ConfigurationManager.AppSettings;

foreach (string key in settings.AllKeys)
{
   string value = settings[key];
}

Enjoy!
