Retrieve XML WP7

我想知道为什么当我检索我的XML时,我无法从中获取任何项目。
所以基本上我使用手机连接到我的网络服务。
XML 返回三倍目录信息和文件信息。

在Windows Phone 7应用程序上的代码上,我从正确的URL下载xml后正在使用这段代码:
void wc_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
if (e.Error == null)
{
XDocument xdoc = XDocument.Parse(e.Result, LoadOptions.None);
var folders = from query in xdoc.Descendants("DirectoryInfo")
select new Folder
{
Name = (string)query.Element("OriginalPath"),
};
listBox2.ItemsSource = folders;
}
}
我收到此错误:
'System.Collections.IEnumerable' does not contain a definition for 'System' and no extension method 'System' accepting a first argument of type 'System.Collections.IEnumerable' could be found (are you missing a using directive or an assembly reference?)
不知道错误,但没有返回元素的问题是因为您在DirectoryInfo
元素上应用了一个命名空间,因此您必须使用它进行搜索:
void wc_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
if (e.Error == null)
{
XDocument xdoc = XDocument.Parse(e.Result, LoadOptions.None);
XNamespace aNamespace = XNamespace.Get("http://schemas.datacontract.org/2004/07/System.IO");
var folders = from query in xdoc.Descendants(aNamespace.GetName("DirectoryInfo"))
select new Folder
{
Name = (string)query.Element("OriginalPath"),
};
listBox2.ItemsSource = folders;
}
}
