Metro应用如何阅读XML API？ [英] Metro Application How to Read XML API?

问题描述

好了，所以我想学习如何使用XAML工作和如何使用Visual Studio 11开发者预览版，以建立新的窗口城域应用。

Ok so I am trying to learn how to work with XAML and how to build new windows metro applications using Visual Studio 11 Developer Preview.

我有一个问题，虽然我不知道如何读取XML文件，我用它来使用C＃以同样的方式。例如，下面是我做到了过去。

I have a problem though I don't know how to read XML files the same way I use to using C#. For example here is how I did it in the past.

private void Button_Click(object sender, RoutedEventArgs e)
        {
            string UrlString = "http://v1.sidebuy.com/api/get/73d296a50d3b824ca08a8b27168f3b85/?city=nashville&format=xml";
            XmlTextReader reader = new XmlTextReader(UrlString);
            XmlNodeType type;

            while (reader.Read())
            {
                type = reader.NodeType;

                if ((type == XmlNodeType.Element) && (reader.Name == "highlights"))
                    {
                        reader.Read();
                        if (reader.Value != "" && reader.Value != null)
                        {
                            listBox1.Items.Add(reader.Value);
                        }
                    }
                }
        }

不过，这会不会在我的地铁应用程序。我需要知道如何为地铁做到这一点。显然XmlTextReader的是不再有效。任何代码或建议吗？

But this won't work in my metro application. I need to know how to do this for metro. Apparently XmlTextReader is no longer valid. Any code or suggestions?

感谢

推荐答案

您可以使用< A HREF =htt​​p://msdn.microsoft.com/en-us/library/windows/apps/br206266.aspx相对=nofollow> XmlDocument.LoadFromUriAsync 。这也应该让你的代码简单了很多。

You can use XmlDocument.LoadFromUriAsync. This should also make your code a lot simpler.

private async void Button_Click(object sender, RoutedEventArgs e)
        {
            string UrlString = "http://v1.sidebuy.com/api/get/73d296a50d3b824ca08a8b27168f3b85/?city=nashville&format=xml";
            var xmlDocument = await XmlDocument.LoadFromUriAsync(UrlString);

            //read from xmlDocument for your values.
         }
