/** Frame - 框架控件，用于导航内容（继承自 ContentControl, 请参见 /Controls/BaseControl/ContentControlDemo/）*     BackStackDepth - 返回 stack 中的条目数*     BackStack - 返回向后导航历史记录的 PageStackEntry 实例的集合（可以根据需求对集合增删改查）*     ForwardStack - 返回向前导航历史记录的 PageStackEntry 实例的集合（可以根据需求对集合增删改查）*     CanGoBack - 可否可以向后导航*     CanGoForward - 可否可以向前导航*     GoBack() - 向后导航，可以指定过渡效果*     GoForward() - 向前导航*     Navigate() - 导航到指定的 Type，可以传递一个 object 类型的参数，可以指定过渡效果*     CurrentSourcePageType - 获取 Frame 当前内容的 Type*     SourcePageType - 获取或设置 Frame 当前内容的 Type* *     CacheSize - 所支持的最大缓存页数，默认值 10*         CacheSize 与被导航的页的 Page.NavigationCacheMode 属性相关（详见 Frame1.xaml.cs 和 Frame2.xaml.cs 的示例代码）*             NavigationCacheMode.Disabled - 每次导航到页时，都重新实例化此页，默认值（CacheSize 无效）*             NavigationCacheMode.Enabled - 每次导航到页时，首先缓存此页，此时如果已缓存的页数大于 CacheSize，则按先进先出的原则丢弃最早的缓存页（CacheSize 有效）*             NavigationCacheMode.Required - 每次导航到页时，都缓存此页（CacheSize 无效）* *     Navigating - 导航开始时触发的事件*     Navigated - 导航完成后触发的事件*     NavigationFailed - 导航失败时触发的事件*     NavigationStopped - 导航过程中，又请求了一个新的导航时触发的事件*     *     GetNavigationState() - 获取 Frame 当前的导航状态，返回字符串类型的数据，仅当导航无参数传递或只传递简单参数（int, char, string, guid, bool 等）时有效*     SetNavigationState(string navigationState) - 将 Frame 还原到指定的导航状态*     *     * PageStackEntry - 保存在 stack 中的页对象*      SourcePageType - 获取此页的类型*      Parameter - 获取之前导航至此页时的参数** * NavigationEventArgs - 导航的事件参数*     NavigationMode - 导航方式，只读（Windows.UI.Xaml.Navigation.NavigationMode 枚举）*         New, Back, Forward, Refresh*     Parameter - 传递给导航目标页的参数，只读*     SourcePageType - 导航的目标页的类型，只读*     *     * 注：* 1、关于导航过程中的过渡效果请参见 /Animation/ThemeTransition/NavigationTransitionInfo/ 中的内容* 2、Frame 中与过渡效果有关的是 GoBack() 和 Navigate() 中的 NavigationTransitionInfo 类型的参数*/using System;
