C＃地铁应用UI更新 [英] C# Metro App UI update

问题描述

我的问题是一样的为此链接 。

My problem is just the same as this link.

我工作在新的WinRT在C＃中（win8的发布预览）城域应用。
的问题是：我的应用我的程序运行的在后台线程从服务器接收邮件（其实，我移植一个XMPP客户端应用程序）。一些信息应在用户界面进行更新。

I am working on the new WinRT for Metro Applications in C#(win8 release preview). The problem is: My app My program runs a thread in the background which receives messages from the server(In fact, I ported a XMPP client app). Some information should be updated in the UI.

我曾尝试该链接。第二种方法似乎会为我工作，但我发现的没有Dispatcher.Invoke（...）在VS2012RC智能感知，这意味着不存在这种扩展方法。

I have tried that link. The second method seems would work for me, but I has found there is no Dispatcher.Invoke(...) in the VS2012RC intellisense which means there is no this extension method.

仔细搜索后，我想也许此链接 能帮助我。但我不知道如何与我在这种情况下应用程序启动（因为我是C＃初学者）。

After searching carefully, I think maybe this link can help me. But I have no idea how to start with my application in this scenario (since I am a beginner in C#).

你能不能给我一些建议吗？如果你表现出一定的代码片段，这将有助于我这么多，我将不胜感激。
非常感谢

Can you give me some advice? I would appreciate if you show some code snippet that would help me so much. Thanks a lot.

推荐答案

在某处，UI线程运行：

Somewhere in your UI thread run :

CoreDispatcher dispatcher = Windows.UI.CoreWindow.GetForCurrentThread().Dispatcher;

然后从你的后台线程调用 RunAsync 功能在调度员刚创建变量。

dispatcher.RunAsync(DispatcherPriority.Normal, <delegate to run on UI thread>);
