As JP Alioto mentioned you should use the WebView control.

正如JP Alioto所提到的,你应该使用WebView控件。

You can use the NavigateToString method to load the HTML. Or use Navigate to request a URI.

您可以使用NavigateToString方法加载HTML。或使用Navigate来请求URI。

There are issues however with using the WebView control, specifically it is rendered differently and is not a standard control, this means things like your app bar or settings pane will not render on top of the WebView, there is a workaround by using the WebViewBrush to "paint" the WebView to standard control such as a rectangle when needed.

但是使用WebView控件存在问题,特别是它呈现的方式不同而且不是标准控件,这意味着应用栏或设置窗格之类的内容无法在WebView上呈现,通过使用WebViewBrush进行解决方法在需要时将WebView“绘制”到标准控件(如矩形)。

Also you can make a screenshot of the webpage you want to display. But to make a screenshot of webpage it's also not easy to do, but I offer you to make it with some special sites wich are created to take screenshot of other websites. Then you can download an image this sites return and open and display it in your windows 8 app. I show You some example how to I did that:

您还可以制作要显示的网页的屏幕截图。但是要制作网页的截图并不容易,但是我建议您使用一些特殊的网站来制作,以截取其他网站的截图。然后,您可以下载此网站返回并打开的图像,并将其显示在您的Windows 8应用程序中。我告诉你如何做到这一点:

 StorageFolder screens = await Windows.ApplicationModel.Package.Current.InstalledLocation.CreateFolderAsync(@"Screens\" + folderName, CreationCollisionOption.GenerateUniqueName);
 var downloader = new BackgroundDownloader();
 IStorageFile file = await screens.CreateFileAsync(fname, CreationCollisionOption.GenerateUniqueName);
 string my_uri = "http://api.snapito.com/web/e3c351d5994134eb1aea855ce78e296c3292d48a/lc/" + url + "?type=jpeg";
 DownloadOperation download = downloader.CreateDownload(new System.Uri(my_uri), file);
 await download.StartAsync();

I think there are only two options but none of them are really good:

我认为只有两种选择,但它们都不是很好:

• Use WebView and transform your HTML with CSS and other techniques to look native. Use the ScriptNotify and NavigationStarting and other events to navigate to another page. In W8.1 the WebView is much better (eg. treated as regular control not floating over all other controls,...)

  使用WebView并使用CSS和其他技术转换HTML以查看本机。使用ScriptNotify和NavigationStarting以及其他事件导航到另一个页面。在W8.1中,WebView要好得多(例如,视为常规控件而不是浮动在所有其他控件上,......)

• Parse your HTML and generate native elements. I started such an implementation and created a XAML control to display HTML with native controls (see https://mytoolkit.codeplex.com/wikipage?title=HtmlTextBlock). However if you have complex HTML (eg iframes, etc.) this may not work and you have no other choice than to use the WebView control.

  解析HTML并生成本机元素。我开始实现这样的实现并创建了一个XAML控件来显示带有本机控件的HTML(请参阅https://mytoolkit.codeplex.com/wikipage?title=HtmlTextBlock)。但是,如果您有复杂的HTML(例如iframe等),这可能不起作用,除了使用WebView控件之外别无选择。
