TriggerCollection 类型公开以下成员。

属性

	名称	说明
	Count	Gets the number of objects in the referenced collection. （从 SmoCollectionBase 继承。）
	IsSynchronized	Gets the Boolean property value that specifies whether access to the collection is synchronized and therefore thread-safe. （从 SmoCollectionBase 继承。）
	Item[Int32]	Gets a Trigger object in the collection by index number.
	Item[String]	Gets a Trigger object in the collection by name.
	Parent	Gets the Table object that is the parent of the Trigger object.
	SyncRoot	Gets an object that can be used to synchronize access to the collection. （从 SmoCollectionBase 继承。）
