屬性

	名稱	說明
	Count	Gets the number of objects in the referenced collection. (繼承自 SmoCollectionBase。)
	IsSynchronized	Gets the Boolean property value that specifies whether access to the collection is synchronized and therefore thread-safe. (繼承自 SmoCollectionBase。)
	Item[ ( [ ( Int32] ) ] )	Gets a UserDefinedType object in the collection by index number.
	Item[ ( [ ( String] ) ] )	Gets a UserDefinedType object in the collection by name.
	Item[ ( [ ( String, String] ) ] )	Gets a UserDefinedType object in the collection by name and schema.
	Parent	Gets the Database object that is the parent of the UserDefinedType object.
	SyncRoot	Gets an object that can be used to synchronize access to the collection. (繼承自 SmoCollectionBase。)
