Eigenschaften

	Name	Beschreibung
	Count	Gets the number of objects in the referenced collection. (Geerbt von SmoCollectionBase.)
	IsSynchronized	Gets the Boolean property value that specifies whether access to the collection is synchronized and therefore thread-safe. (Geerbt von SmoCollectionBase.)
	Item[ ( [ ( Int32] ) ] )	Gets a ForeignKeyColumn object in the collection by index number.
	Item[ ( [ ( String] ) ] )	Gets a ForeignKeyColumn object in the collection by name.
	Parent	Gets the ForeignKey object that is the parent of the ForeignKeyColumnCollection object.
	SyncRoot	Gets an object that can be used to synchronize access to the collection. (Geerbt von SmoCollectionBase.)
