Propriétés

	Nom	Description
	Count	Gets the number of objects in the referenced collection. (hérité de SmoCollectionBase.)
	IsSynchronized	Gets the Boolean property value that specifies whether access to the collection is synchronized and therefore thread-safe. (hérité de SmoCollectionBase.)
	Item[ ( [ ( Int32] ) ] )	Gets an IndexedColumn object in the collection by index number.
	Item[ ( [ ( String] ) ] )	Gets an IndexedColumn object in the collection by name.
	Parent	Gets the Server object that is the parent of the IndexedColumnCollection object.
	SyncRoot	Gets an object that can be used to synchronize access to the collection. (hérité de SmoCollectionBase.)
