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 a UserDefinedAggregate object in the collection by index number.
	Item[ ( [ ( String] ) ] )	Gets a UserDefinedAggregate object in the collection by name.
	Item[ ( [ ( String, String] ) ] )	Gets a UserDefinedAggregate object in the collection by name and schema.
	Parent	Gets the Database object that is the parent of the UserDefinedAggregate object.
	SyncRoot	Gets an object that can be used to synchronize access to the collection. (hérité de SmoCollectionBase.)
