在WP8上使用WCF進行LINQ to SQL時，出現“ System.InvalidOperationException”

Question

這是發生異常的代碼：

public Listado()
    {
        InitializeComponent();

        ListadoWebService();
    }
    public void ListadoWebService()
    {
       // InitializeComponent();
        ServiceTours.ServiceToursClient cl = new ServiceTours.ServiceToursClient(); 
        cl.ListadoCompleted += new EventHandler<ListadoCompletedEventArgs>(Listado2);
        cl.ListadoAsync();
    }
    private void Listado2(object sender, ListadoCompletedEventArgs e)
    {
        listB.ItemsSource = e.Result; // listB is ListBox in WP8
    }

我得到以下異常：

An exception of type 'System.InvalidOperationException' occurred in System.ServiceModel.ni.dll but was not handled in user code

我想說我直接在MSDN上遵循了本教程

因此，最終的服務參考URL為：http：// IP /WcfTours/ServiceTours.svc。 //99.99.99代表IP

domain public和private允許Allow an app through Windows Firewall World Wide Web Services (HTTP) 。

Virtual Directory已創建。

有人可以幫我設置endpoint嗎？

異常消息：

Answer 1

在項目中添加Web Service引用后，就會在項目的根文件夾中創建一個新的ServiceReferences.ClientConfig文件。 在某個地方打開它並尋找：

<client>
    <endpoint .... name="endpointName" />
<endpoint .... name="endpointName2" />
</client>

就您而言，那里有多個記錄。 因此，請選擇適當的名稱並將其傳遞給ServiceToursClient的構造函數。

new ServiceToursClient("endpointName")
