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;
}

Public Shared Function GetElementInformation() _
As ElementInformation

    ' Get the current configuration file.
    Dim config _
    As System.Configuration.Configuration = _
    ConfigurationManager.OpenExeConfiguration( _
    ConfigurationUserLevel.None)

    ' Get the section.
    Dim section As UrlsSection = CType( _
    config.GetSection("MyUrls"), UrlsSection)

    ' Get the element.
    Dim url As UrlConfigElement = _
    section.Simple

    Dim eInfo As ElementInformation = _
    url.ElementInformation

    Return eInfo

End Function 'GetElementInformation

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

<?xml version="1.0" encoding="utf-8"?>  
<configuration>  
  <configSections>  
    <section name="MyUrls" type="Samples.AspNet.UrlsSection,  
      ConfigurationElement, Version=1.0.0.0, Culture=neutral,  
      PublicKeyToken=null" allowDefinition="Everywhere"  
      allowExeDefinition="MachineToApplication"  
      restartOnExternalChanges="true" />  
  </configSections>  
  <MyUrls name="MyFavorites">
