Autofac和RoutingService

Question

我正在尝试构建路由基础结构，并使用Autofac作为IoC容器。我读了wiki，我知道这些步骤：

ContainerBuilder builder = new ContainerBuilder();
builder.Register(c => new Logger()).As<ILogger>();
builder.Register(c => new EchoService(c.Resolve<ILogger>())).As<IEchoService>();

using (IContainer container = builder.Build())
{
    Uri address = new Uri("http://localhost:8080/EchoService");
    ServiceHost host = new ServiceHost(typeof(EchoService), address);

host.AddServiceEndpoint(typeof(IEchoService), new BasicHttpBinding(), string.Empty);

host.AddDependencyInjectionBehavior<IEchoService>(container);

host.Description.Behaviors.Add(new ServiceMetadataBehavior {HttpGetEnabled = true, HttpGetUrl = address});
host.Open();

Console.WriteLine("The host has been opened.");
Console.ReadLine();

host.Close();
Environment.Exit(0);

}

我这里有这个代码来满足我的情况：

builder.RegisterType<RoutingService>().As<ISimplexDatagramRouter>().InstancePerLifetimeScope();

        builder.Register(c =>
        {
            var routingConfiguration = new RoutingConfiguration();
            routingConfiguration.RouteOnHeadersOnly = false;
            return routingConfiguration;
        }).As<RoutingConfiguration>();

        builder.Register(c =>
            {
                var publisherServiceHost = new ServiceHost(typeof(RoutingService));
                publisherServiceHost.AddServiceEndpoint(typeof(ISimplexDatagramRouter), new NetTcpBinding(), "some address");
                publisherServiceHost.Description.Behaviors.Add(new RoutingBehavior(c.Resolve<RoutingConfiguration>()));
                return publisherServiceHost;
            }).As<ServiceHost>();

这不起作用，因为我从Autofac收到错误，因为它找不到RoutingService的condtructor（它的构造函数是私有的）。

你有任何提示吗？

据我所知，RoutingService类没有定义构造函数。你可以看到，如果你试图这样做：

RoutingService rs = new RoutingService（）;

编译器会收到错误消息：  System.ServiceModel.Routing.RoutingService类型没有定义构造函数。
