	Item[ ( [ ( Int32] ) ] )	Gets a UserDefinedDataType object in the collection by index number.
	Item[ ( [ ( String] ) ] )	Gets a UserDefinedDataType object in the collection by name.
	Item[ ( [ ( String, String] ) ] )	Gets a UserDefinedDataType object in the collection by name and schema.
	Parent	Gets the Database object that is the parent of the UserDefinedDataType object.
	SyncRoot	Gets an object that can be used to synchronize access to the collection. (Herdado de SmoCollectionBase.)
