在 Silverlight 中设置 HtmlPage.Window.CurrentBookmark 属性时禁止导航
我有一个场景，我需要更改 HtmlPage.Window.CurrentBookmark 属性，但我想在不导致 Silverlight 应用程序重新加载的情况下执行此操作。现在，我正在这样做，但它导致应用程序重新启动：
public void SetBookmark(string authenticationGroupTag, string ownerUserTag, string roomName)
{
string bookmark = GetBookmark(authenticationGroupTag, ownerUserTag, roomName);
HtmlPage.Window.CurrentBookmark = bookmark;
// HtmlPage.Window.Eval("window.location.hash='" + bookmark + "'");
}
这种特定行为（重新启动应用程序）似乎没有在任何地方记录，所以我想知道我是否只是做错了。我尝试捕获各种与导航相关的事件（Page.OnNavigateFrom 或 RootFrame.Navigating），但这些事件实际上都没有被触发：应用程序只是卸载然后重新加载。
所以我想我的问题有两个部分：（1）这是预期的行为，还是我只是做错了什么？ (2) 如果这是预期的行为，是否有人想出解决方法？有没有办法在不重新加载 Silverlight 应用程序的情况下更新“#”之后的 URL 部分？
I have a scenario where I need to change the HtmlPage.Window.CurrentBookmark property, but I want to do it without causing the Silverlight application to reload. Right now, I'm doing this, but it's causing the application to restart:
public void SetBookmark(string authenticationGroupTag, string ownerUserTag, string roomName)
{
string bookmark = GetBookmark(authenticationGroupTag, ownerUserTag, roomName);
HtmlPage.Window.CurrentBookmark = bookmark;
// HtmlPage.Window.Eval("window.location.hash='" + bookmark + "'");
}
That particular behavior -- restarting the application -- doesn't seem to be documented anywhere, so I wonder if I'm just doing it wrong. I've tried catching various navigation related events (either Page.OnNavigatedFrom or RootFrame.Navigating), but neither of those actually get fired: the app just unloads and then reloads.
So I guess I have two parts to my question: (1) Is this the expected behavior, or am I just doing something wrong? and (2) If it is the expected behavior, has anyone come up with a workaround for it? Is there a way to update the portion of the URL after the "#" without reloading the Silverlight application?

事实证明，这只是一个长期被注意到的问题的变体，即当 (a) 用户在重定向后到达当前页面，以及 (b) 您更改 window.location 时，Internet Explorer 会刷新页面.hash。换句话说，这是一个 IE 问题（在 IE9 中仍然没有修复！），而不是 Silverlight 问题。 Firefox 和 Chrome 一切正常。 （请参阅 在 IE 中刷新 javascript location.hash 和 带有片段标识符的Response.Redirect在稍后使用location.hash时会导致意外刷新 了解更多详细信息和一些建议的解决方法。）
Turns out that this is just a variant of a problem that's been long noted, namely, that Internet Explorer refreshes the page when (a) the user has arrived at the current page after a redirect, and (b) you change the window.location.hash. In other words, this is an IE issue (still not fixed in IE9!), not a Silverlight problem. Everything behaves correctly with Firefox and Chrome. (See javascript location.hash refreshing in IE and Response.Redirect with a fragment identifier causes unexpected refresh when later using location.hash for more details, and some suggested workarounds.)
