注解

访问 List 控件的 Items 属性或 SelectionList 控件的 Items 属性将检索 MobileListItemCollection 对象。Accessing the Items property of a List control or the Items property of a SelectionList control retrieves a MobileListItemCollection object. 您可以在运行时在集合中添加或移除项。You can add or remove items from the collection at run time.

MobileListItemCollection 对象继承自 ICollection 接口。A MobileListItemCollection object inherits from the ICollection interface.
