Question

我通过WebClient方法调用一个restful服务来返回一些XML。然后，我想解析XML，从每个节点中提取特定字段，然后将其转换为数组。

我有代码正在检索XML并将其填充到列表框中。出于某种原因，我无法弄清楚如何将其转换为对象数组。

到目前为止

代码：

    private void button1_Click(object sender, RoutedEventArgs e)
    {
        WebClient wc = new WebClient();
        wc.DownloadStringCompleted += HttpsCompleted;
        wc.DownloadStringAsync(new Uri(requestString));
    }

    private void HttpsCompleted(object sender, DownloadStringCompletedEventArgs e)
    {
        if (e.Error == null)
        {
            XDocument xdoc = XDocument.Parse(e.Result, LoadOptions.None);

            var data = from query in xdoc.Descendants("entry")
                       select new DummyClass
                       {
                           Name = (string)query.Element("title"),
                           Kitty = (string)query.Element("countryCode")
                       };
            listBox1.ItemsSource = data;
        }
    }

}

如何将每个节点转换为数组中的对象？

非常感谢提前！将

Answer 1

有什么问题

// convert IEnumerable linq query to an array
var array = data.ToArray(); // could also use .ToList() for a list
// access like this
MessageBox.Show(array[0].Kitty);

这将为您提供一组DummyClass个对象，来自linq查询生成的IEnumerable<DummyClass>。

此外，甚至可能不需要阵列。如果您需要做的就是迭代数据，只需在foreach对象上执行data即可。

使用Silverlight / Windows Phone将XML解析为对象数组
