我想问一个让我一直抓狂的问题@_@ 我为 Windows Phone 8 制作了一个应用程序，它从 WCF 服务检索数据。 幸运的是，我的同事为我提供了服务。但是，当我使用该服务时，我收到了此错误。

到处搜索后，我得到了这篇好文章。 http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj684580(v=vs.105).aspx
但是，我读了它，但还是不明白。为什么？ 因为我的服务是用 C# 类编写的，而不是作为 Web 服务。所以我找不到 IIS 服务。
这是我生成数据的代码。
public PurchaseInvoiceMainPage()
{
InitializeComponent();
this.Loaded += new RoutedEventHandler(purchaseInvoice_Loaded);
}
private void purchaseInvoice_Loaded(object sender, RoutedEventArgs e)
{
NavcoreNavfinServiceClient client = new NavcoreNavfinServiceClient();
client.GetAllCompleted += new EventHandler<GetAllCompletedEventArgs>(client_getAllPurchaseInvoice);
client.GetAllAsync("509A7214-D3A9-47E7-9BB4-232E670ED650");
}
private void client_getAllPurchaseInvoice(object sender, GetAllCompletedEventArgs e)
{
if (e.Error == null)
{
purchaseDataList.ItemsSource = e.Result;
}
}
而且，这是我的服务，它返回结果。
public System.Collections.ObjectModel.ObservableCollection<NavFinance.NavFinData.vwPurchaseInvoice> EndGetAll(System.IAsyncResult result) {
object[] _args = new object[0];
System.Collections.ObjectModel.ObservableCollection<NavFinance.NavFinData.vwPurchaseInvoice> _result = ((System.Collections.ObjectModel.ObservableCollection<NavFinance.NavFinData.vwPurchaseInvoice>)(base.EndInvoke("GetAll", _args, result)));
return _result;
}
我在这一行得到了异常。
System.Collections.ObjectModel.ObservableCollection<NavFinance.NavFinData.vwPurchaseInvoice> _result = ((System.Collections.ObjectModel.ObservableCollection<NavFinance.NavFinData.vwPurchaseInvoice>)(base.EndInvoke("GetAll", _args, result)));
我使用了许多我发现的技巧，从增加最大字节大小等开始。 它仍然不起作用。 请有人帮助我。我真的很困惑TT_TT
这是我使用的服务。

大家的任何回答都会让我思考更多，请给出答案。
问候， 布迪·普拉塞蒂奥

此错误表明您的应用程序无法与该服务通信。您是否在手机/模拟器 Internet Explorer 中尝试服务 URL 以确保该 URL 可以访问？
