屬性

	名稱	說明
	Count	Gets the number of objects in the referenced collection. (繼承自 SmoCollectionBase。)

	Item[Int32]	Gets an ApplicationRole object in the collection by index number.
	Item[String]	Gets an ApplicationRole object in the collection by name.
	Parent	Gets the Database object that is the parent of the ApplicationRoleCollection object.
