public sealed class SectionInformation

The SectionInformation object contains the metadata about an individual section within the configuration hierarchy. This object can be used in order to validate and change the properties of an individual section.

The SectionInformation class is introduced in the .NET Framework version 3.5 Service Pack 1. For more information, see .NET Framework 3.5 Architecture.

The following example shows how to get the SectionInformation metadata that is associated with a ConfigurationSection object.

static public SectionInformation 

    // Get the current configuration file.
    System.Configuration.Configuration config =

    // Get the section.
    UrlsSection section =

    SectionInformation sInfo = 

    return sInfo;


The following example is an excerpt of the configuration file that is used by the previous example.

<?xml version="1.0" encoding="utf-8"?>
    <section name="MyUrls" type="Samples.AspNet.UrlsSection,
      ConfigurationElement, Version=, Culture=neutral,
      PublicKeyToken=null" allowDefinition="Everywhere"
      restartOnExternalChanges="true" />
  <MyUrls name="MyFavorites">
    <simple name="Contoso" url="" port="8080" />
      <clear />
      <add name="Microsoft" url="" port="0" />
