The DatabaseCollection type exposes the following members.

Properties

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