Açıklamalar

ConfigurationSectionGroupCollection Bir nesne koleksiyonunda yineleme yapmak için sınıfını ConfigurationSectionGroup kullanın. Özelliğini veya özelliğini kullanarak SectionGroups bu nesne koleksiyonuna SectionGroups erişebilirsiniz.

sınıfı, ConfigurationSectionGroupCollection sınıfını genişleten ConfigurationSectionGroup özel türlerin oluşturulmasında da kullanılır.

Özellikler

Count	Örnekte bulunan anahtar/değer çiftlerinin NameObjectCollectionBase sayısını alır. (Devralındığı yer: NameObjectCollectionBase)
IsReadOnly	Örneğin salt okunur olup olmadığını NameObjectCollectionBase belirten bir değer alır veya ayarlar. (Devralındığı yer: NameObjectCollectionBase)
Item[Int32]	ConfigurationSectionGroup Dizini koleksiyondan belirtilen nesneyi alır.
Item[String]	ConfigurationSectionGroup Adı koleksiyondan belirtilen nesneyi alır.
Keys	Örnekteki tüm anahtarları NameObjectCollectionBase içeren bir NameObjectCollectionBase.KeysCollection örneği alır. (Devralındığı yer: NameObjectCollectionBase)
