在服务

Question

在下面的代码中，我收到错误消息。我想这是简单或不可能的事情，因为我无法与谷歌找到任何东西。无论如何，我得到的错误是：

  

合同名称＆＃39; SchippersStop.Wcf.Balie.Interfaces.IBalie＆＃39;无法在服务＆System; Service.ServiceModel.Routing.RoutingService＆＃39;。

实施的合同列表中找到。

当我尝试将ServiceEndpoint添加到主机时发生错误。

            ServiceHost host = new ServiceHost(typeof(RoutingService));
            string path = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);

            foreach (string dll in Directory.GetFiles(path, "*.dll"))
            {
                Assembly assembly = Assembly.LoadFile(dll);
                foreach (Type type in assembly.GetTypes())
                {
                    if (type.GetInterfaces().Contains(typeof(ISchippersStopSvc)))
                    {
                        DiscoveryClient discoveryClient = new DiscoveryClient(new UdpDiscoveryEndpoint());

                        FindCriteria findCriteria = new FindCriteria(type);
                        findCriteria.Duration = TimeSpan.FromSeconds(10);

                        FindResponse findResponse = discoveryClient.Find(findCriteria);

                        EndpointDiscoveryMetadata discoveryMetadata = findResponse.Endpoints.First();
                        Uri uri = discoveryMetadata.Address.Uri;
                        string routerAddress = uri.AbsoluteUri.Replace(uri.Host, "0.0.0.0");

                        DiscoveryClientBindingElement discoveryBindingElement = new DiscoveryClientBindingElement();
                        discoveryBindingElement.FindCriteria = findCriteria;
                        discoveryBindingElement.DiscoveryEndpointProvider = new UdpDiscoveryEndpointProvider();
                        CustomBinding binding = new CustomBinding();
                        binding.Elements.Insert(0, discoveryBindingElement);

                        ContractDescription contract = ContractDescription.GetContract(type);
                        RoutingConfiguration rc = new RoutingConfiguration();
                        rc.RouteOnHeadersOnly = true;

                        string groupName = Guid.NewGuid().ToString();
                        foreach (EndpointDiscoveryMetadata endpoint in findResponse.Endpoints)
                        {
                            List<ServiceEndpoint> endpointList = new List<ServiceEndpoint>();
                            ServiceEndpoint client = new ServiceEndpoint(contract, binding, new EndpointAddress(endpoint.Address.Uri.AbsoluteUri));
                            endpointList.Add(client);
                            endpointList.AddRange(findResponse.Endpoints.Except(new List<EndpointDiscoveryMetadata>() { endpoint }).Select(s => new ServiceEndpoint(contract, binding, new EndpointAddress(s.Address.Uri.AbsoluteUri))).ToList());
                            endpointList.ForEach(f => f.EndpointBehaviors.Add(new ClientTrackerEndpointBehavior() { }));
                            rc.FilterTable.Add(new CustomMessageFilter(groupName), endpointList);
                        }

                        RoutingBehavior routing = new RoutingBehavior(rc);
                        host.Description.Behaviors.Add(routing);

                        // Here the error occurs
                        host.AddServiceEndpoint(type, binding, routerAddress);
                    }
                }
            }

目标是将在网络上发现的WCF服务添加到路由器。但是我想以这样的方式进行设置：我不需要知道有关服务的任何信息，路由器可以检测所有必要的配置，之后它可以动态加载它们。我唯一要提供给路由器的是ServiceContract。路由器可以根据它们继承的公共接口检测具有ServiceContract的程序集。

有人可以帮我解决这个错误吗？
