Autofac 和 RoutingService

Question

我正在尝试构建路由基础架构，并使用 Autofac 作为 IoC 容器。我阅读了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);

}

我这里确实有这个代码来满足我的场景：

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 收到一个错误，因为它找不到 RoutingService 的构造函数（它的构造函数是私有的）。

你有什么提示吗？

Answer 1

据我所知，RoutingService 类没有定义构造函数。如果您尝试这样做，您会看到：

RoutingService rs = new RoutingService();

你会从编译器那里得到一个错误，说： System.ServiceModel.Routing.RoutingService 类型没有定义构造函数。
