The following example shows how to get the ElementInformation associated with a ConfigurationElement object.

static public ElementInformation
    GetElementInformation()
{

    // Get the current configuration file.
    System.Configuration.Configuration config =
            ConfigurationManager.OpenExeConfiguration(
            ConfigurationUserLevel.None);

    // Get the section.
    UrlsSection section =
        (UrlsSection)config.GetSection("MyUrls");

    // Get the element.
    UrlConfigElement url = section.Simple;

    ElementInformation eInfo =
        url.ElementInformation;

    return eInfo;

}

The following excerpt shows the configuration used by the previous code example.

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