C# 下载windows phone网站的内容

我正在尝试下载一个网站的html内容。出于某种原因，此代码不起作用。我希望windows phone 7和windows phone 8使用相同的东西。

谢谢。

您的代码对我来说运行正常。您可能遇到了一个错误。为什么不检查一下是否收到任何错误

       public MainPage()
    {
        InitializeComponent();

        // Sample code to localize the ApplicationBar
        //BuildLocalizedApplicationBar();
    }




    private void b1_Click(object sender, RoutedEventArgs e)
    {
        string url = trackingtb.Text;
        LoadSiteContent("http://www.mywebsite.com");

    }

    public void LoadSiteContent(string url)
    {
        //create a new WebClient object
        WebClient client = new WebClient();

        client.DownloadStringCompleted += new DownloadStringCompletedEventHandler(DownloadStringCallback2);
        client.DownloadStringAsync(new Uri(url));
    }

    private  void DownloadStringCallback2(Object sender, DownloadStringCompletedEventArgs e)
    {
        // If the request was not canceled and did not throw
        // an exception, display the resource.
        if (!e.Cancelled && e.Error == null)
        {
            output.Text= (string)e.Result;
            //If you get the cross-thread exception then use the following line instead of the above
            //Dispatcher.BeginInvoke(new Action (() => textBlock1.Text = (string)e.Result));
        }
    }

如果出现错误会发生什么？你在回拨中忽略了这一点。还有，你得到了什么错误？您是否在回调中设置了断点？

private  void DownloadStringCallback2(Object sender, DownloadStringCompletedEventArgs e)
{
    if (e.Error != null)
    {
        // Check the error here
    }
    // If the request was not canceled and did not throw
    // an exception, display the resource.
    else if (!e.Cancelled)
    {
        output.Text= (string)e.Result;
        //If you get the cross-thread exception then use the following line instead of the above
        //Dispatcher.BeginInvoke(new Action (() => textBlock1.Text = (string)e.Result));
    }
}
