How do I load an xml file in XDocument in Silverlight?

XDocument has no load method contr开发者_开发技巧ary to XMLDocument so how do I load an XML content from the Internet with an url ?

Actually, XDocument does have a Load(Uri) method, but it's only for navigating to pages within your app. It's a static method, so you do XDocument xDoc = XDocument.Load("/somepage.xaml");. The documentation for the Load(string) method is here.

If you want to access an external URL, you need to use the WebClient class. Here's an example that I just tested in a Windows Phone 7 app (which is basically SL3):

using System;
using System.Net;
using Microsoft.Phone.Controls;
using System.Xml.Linq;

namespace XDocumentTest
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();
            WebClient wc = new WebClient();
            wc.DownloadStringCompleted += HttpsCompleted;
            wc.DownloadStringAsync(new Uri("http://twitter.com/statuses/public_timeline.xml"));
        }

        private void HttpsCompleted(object sender, DownloadStringCompletedEventArgs e)    
        {        
            if (e.Error == null)        
            {            
                XDocument xdoc = XDocument.Parse(e.Result, LoadOptions.None);            
                TextBlock1.Text = xdoc.FirstNode.ToString();        
            }    
        }
    }
}

This question is similar, but involves https, which I don't think you're dealing with.
