Remarks

Use the ConfigurationSectionGroupCollection class to iterate through a collection of ConfigurationSectionGroup objects. You can access this collection of objects using the SectionGroups property or the SectionGroups property.

The ConfigurationSectionGroupCollection class is also used in the creation of custom types that extend the ConfigurationSectionGroup class.
