Get XML from https using WebClient / HttpWebRequest - WP7

Question

I am trying to get an XML document from a server and store it locally as a string. On the .Net desktop, I did not need it, I just did:

string xmlFilePath = "https://myip/"; XDocument xDoc = XDocument.Load(xmlFilePath); 

However, on WP7, this returns:

 Cannot open 'serveraddress'. The Uri parameter must be a relative path pointing to content inside the Silverlight application XAP package. If you need to load content from an arbitrary Uri, please see the documentation on Loading XML content using WebClient/HttpWebRequest. 

So, I decided to use the WebClient / HttpWebRequest example from here , but now it returns:

 The remote server returned an error: NotFound. 

Is this because XML is an https path? Or because my path does not end in .XML? How to find out? Thanks for any help.

Here is the code:

  public partial class MainPage : PhoneApplicationPage { WebClient client = new WebClient(); string baseUri = "https://myip:myport/service"; public MainPage() { InitializeComponent(); client.DownloadStringCompleted += new DownloadStringCompletedEventHandler( client_DownloadStringCompleted); } private void Button1_Click(object sender, RoutedEventArgs e) { client.DownloadStringAsync (new Uri(baseUri)); } void client_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) { if (e.Error == null) resultBlock.Text = "Using WebClient: " + e.Result; else resultBlock.Text = e.Error.Message; } private void Button2_Click(object sender, RoutedEventArgs e) { HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(new Uri(baseUri)); request.BeginGetResponse(new AsyncCallback(ReadCallback), request); } private void ReadCallback(IAsyncResult asynchronousResult) { HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState; HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(asynchronousResult); using (StreamReader streamReader1 = new StreamReader(response.GetResponseStream())) { string resultString = streamReader1.ReadToEnd(); resultBlock.Text = "Using HttpWebRequest: " + resultString; } } }

I rather think that you have too complicated things. The following is a very simple example that requests an XML document from a URI via HTTPS.

It loads the XML asynchronously as a string, and then uses XDocument.Parse() to load it.

  private void button2_Click(object sender, RoutedEventArgs e) { WebClient wc = new WebClient(); wc.DownloadStringCompleted += HttpsCompleted; wc.DownloadStringAsync(new Uri("https://domain/path/file.xml")); } private void HttpsCompleted(object sender, DownloadStringCompletedEventArgs e) { if (e.Error == null) { XDocument xdoc = XDocument.Parse(e.Result, LoadOptions.None); this.textBox1.Text = xdoc.FirstNode.ToString(); } }
