ConfigurationSection Constructor

Initializes a new instance of the ConfigurationSection class.

Namespace:  System.Configuration
Assembly:  System.Configuration (in System.Configuration.dll)

protected ConfigurationSection()

To use the ConfigurationSection constructor, you need to define a custom section type first. For an example see the ConfigurationSection class overview.

The following example shows how to use the ConfigurationSection constructor. This example assumes that you have created a custom section class named CustomSection. For an example of such a class, see the ConfigurationSection class overview.

        // Create a custom section.
        static void CreateSection()

                CustomSection customSection;

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

                // Create the section entry  
                // in the <configSections> and the 
                // related target section in <configuration>.
                if (config.Sections["CustomSection"] == null)
                    customSection = new CustomSection();
                    config.Sections.Add("CustomSection", customSection);
                    customSection.SectionInformation.ForceSave = true;
            catch (ConfigurationErrorsException err)
