Question

我有一些非常简单的代码，我一直在Windows 8商店应用程序中使用没有任何问题。但是，当我与Windows手机应用程序共享代码时它只是永远挂起。见下面的示例。这将调用任何Web URL并将其源作为字符串返回。 post和get方法都以相同的方式挂起。非常感谢任何帮助，谢谢。

    public static string GetWebSource(string Url)
    {
        HttpClient client = new HttpClient();
        Task<HttpResponseMessage> Resp = client.GetAsync(Url);

        //code hangs on following line forever
        //Resp.status always stays at waiting for activation
        Task.WaitAll(Resp);

        if (Resp.Result.IsSuccessStatusCode)
        {
            Task<string> response = Resp.Result.Content.ReadAsStringAsync();
            Task.WaitAll(response);
            return response.Result;
        }
        return "";
    }

    public static string PostWebSource(string Url, string data)
    {
        HttpClient client = new HttpClient();
        StringContent sc = new StringContent(data);
        Task<HttpResponseMessage> Resp = client.PostAsync(Url, sc);

        //code hangs on following line forever
        //Resp.status always stays at waiting for activation
        Resp.Wait();

        if (Resp.Result.IsSuccessStatusCode)
        {
            Task<string> response = Resp.Result.Content.ReadAsStringAsync();
            Task.WaitAll(response);
            return response.Result;
        }
        return "";
    }

您应该在Windows Phone上使用HttpWebRequest。请看这个链接：http://social.msdn.microsoft.com/Forums/wpapps/en-us/9b4c1ef2-853c-468a-bca8-97477a02583c/httpclient-for-windows-phone-8?forum=wpdevelop
