在WP8上使用WCF进行LINQ to SQL时，出现“ System.InvalidOperationException”

Question

这是发生异常的代码：

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
    }

我得到以下异常：

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

我想说我直接在MSDN上遵循了本教程

因此，最终的服务参考URL为：http：// IP /WcfTours/ServiceTours.svc。 //99.99.99代表IP

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

Virtual Directory已创建。

有人可以帮我设置endpoint吗？

异常消息：

Answer 1

在项目中添加Web Service引用后，就会在项目的根文件夹中创建一个新的ServiceReferences.ClientConfig文件。 在某个地方打开它并寻找：

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

就您而言，那里有多个记录。 因此，请选择适当的名称并将其传递给ServiceToursClient的构造函数。

new ServiceToursClient("endpointName")
