Question

I need to read a xml file, but I have this error when try to read it.

public void load()
{
  IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication();
  IsolatedStorageFileStream fileStream;
  try
  {
    fileStream = myIsolatedStorage.OpenFile("sites.xml", FileMode.Open, 
      FileAccess.Read);
  }
  catch (Exception)
  {
    fileStream = myIsolatedStorage.CreateFile("sites.xml");
    XDocument sites= new XDocument(new XElement("root"));
    fileStream = myIsolatedStorage.OpenFile("sites.xml", FileMode.Open, 
      FileAccess.Read);
  }          

  List<Site> listSites= new List<Site>();

  using (StreamReader file= new StreamReader(fileStream))
  {
    XDocument doc= XDocument.Load(file);

    foreach (XElement elemento in doc.Elements())
    {
      String name= elemento.Element("name").Value;
      String url = elemento.Element("url").Value;
      listSites.Add(new Site(name));
    }
    lstSites.ItemsSource = listSites;
  }
}

On the line

XDocument doc= XDocument.Load(file); 

I receive the error in the subject. Can you help me ?

Maybe you should change the way you are working with xml files and isolated storage. you could create a Site class containing your name and url properties and serialize a list of these to the isolated storage.
