本文介绍了从 URL 读取 XML 并绑定到 WP7 中的列表框的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个 WP7,它读取 XML 文件,获取一些元素并将它们绑定到 listbox
代码如下:
I have a WP7 which read a XML file, take some elements and bind them to a listbox
Here is the code:
XDocument data = XDocument.Load("file.xml");
var persons = from query in data.Descendants("Table")
select new Person
{
Phone = (string)query.Element("Phone"),
Name= (string)query.Element("Name"),
};
listBox1.ItemsSource = persons;
public class Person
{
string Phone;
string Name;
public string Phone
{
get { return phone; }
set { phone = value; }
}
public string ame
{
get { return name; }
set { name = value; }
现在我想做同样的事情,但 XML 文件位于 URL 上.
Now i want to do the same but the XML file is on a URL.
有人可以帮我吗?
谢谢
推荐答案
您应该使用 WebClient
类从 URL 中获取内容,然后将其解析为 XDocument
对象:
You should use WebClient
class to get the content from URL and then parse it to XDocument
object:
你可以试试这样的:
WebClient wc = new WebClient();
wc.DownloadStringCompleted += HttpCompleted;
wc.DownloadStringAsync(new Uri("http://domain/path/file.xml"));
和 HttpCompeted:
and the HttpCompeted:
private void HttpCompleted(object sender, DownloadStringCompletedEventArgs e)
{
if (e.Error == null)
{
XDocument xdoc = XDocument.Parse(e.Result, LoadOptions.None);
// do something with the XDocument here
}
}
