我正在尝试让一些应用程序连接到 WCF 服务。除了在实际设备上进行调试外，一切都运行良好。它报告超时异常。我在使用模拟器时没有问题，那里一切正常。

这是我主页上的代码：

public partial class MainPage: PhoneApplicationPage
{
    // Constructor
    public MainPage()
    {
        InitializeComponent();
        ServiceReference1.WCFClient serviceClient = new ServiceReference1.WCFClient();

        serviceClient.LoadExamsAsync("Marco");
        serviceClient.LoadExamsCompleted += serviceClient_LoadExamsCompleted;


    }

    void serviceClient_LoadExamsCompleted(object sender, ServiceReference1.LoadExamsCompletedEventArgs e)
    {
        lls2.ItemsSource = e.Result; // longlistselector
    }
 }

来自 IExams.cs：

[ServiceContract]
public interface IExams
{

    [OperationContract]
    List<LoadExamsResult> LoadExams();

}

并来自 Exams.svc.cs：

public class ExamsService : IExams
{
    public ExamsDataClassesDataContext data { get; set; }
    public ExamsService()
    {
        data = new ExamsDataClassesDataContext();
    }

    public List<LoadExamsResult> LoadExams(string un)
    {
        return data.LoadExams(un).ToList();
    }
}

LinqToSql 类是自动创建的，我从 Sql Server 中的数据库调用存储过程。

这是我的 web.config 文件：

<?xml version="1.0"?>
<configuration>
  <connectionStrings>
    <add name="ConnectionString" connectionString="Data Source=Alex;Initial        Catalog=Ispiti;Integrated Security=True"

    <!--

      -->
    <directoryBrowse enabled="true"/>
   </system.webServer>

</configuration>

并来自我的 ServiceReferences.ClientConfig

<configuration>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="basicHttpBinding_IExams" maxBufferSize="2147483647"

        </client>
    </system.serviceModel>

如果您的本地计算机上有 WCF 服务，则需要允许通过防火墙进行外部连接。此外，您需要将设备连接到 PC 的同一网络。即使这样，您也可以尝试使用 PC IP 而不是名称（使用http://192.168.1.23/service而不是http://mypcname/service）连接到服务。
