我的 WCF 服务是这样工作的：您通过调用服务方法订阅它们，比如 Subscribe()。他们通过回调通道将结果发回给您，例如 MessageReceived(string message)。我现在的问题是我的路由器仅将第一个订阅调用路由到其端点列表中的第一个服务。结果，我只从一个服务端点获取回调消息，而不是两者。我希望订阅两个端点并从两个端点获取回调。这是我的代码（请注意，我在 serviceAddresses 字符串中有两个 net.tcp 地址）：

private void StartAggregatorHost(List<string> serviceAddresses)
{
        // Create a new service host for the routing service (note that RoutingService is a pre-defined Microsoft service model type which routes SOAP messages).
        aggregatorHost = new ServiceHost(typeof(RoutingService));

        // Set up the router address. A logger client will now connect to this address to get logged messages.
        string fqdn = System.Net.Dns.GetHostEntry("localhost").HostName;
        string routerAddress = string.Format("net.tcp://{0}:2099/LogAggregator", fqdn);

        // Set up our router binding.
        NetTcpBinding routerBinding = new NetTcpBinding(SecurityMode.None, true);
        routerBinding.SendTimeout = new TimeSpan(0, 1, 0);       
        routerBinding.ReceiveTimeout = new TimeSpan(25, 0, 0);
        routerBinding.MaxReceivedMessageSize = int.MaxValue;
        routerBinding.MaxConnections = int.MaxValue;
        routerBinding.ListenBacklog = int.MaxValue;
        routerBinding.ReliableSession.Enabled = true;
        routerBinding.ReliableSession.Ordered = true;
        routerBinding.ReliableSession.InactivityTimeout = new TimeSpan(15, 0, 0, 0);

        // Define the type of router in use. For duplex sessions like in our case, we want to use the IDuplexSessionRouter.
        Type contractType = typeof(IDuplexSessionRouter);

        // Add the endpoint that the router will use to recieve and relay messages. Note the use of System.ServiceModel.Routing.IDuplexSessionRouter.
        aggregatorHost.AddServiceEndpoint(contractType, routerBinding, routerAddress);

        // Create the endpoint list that contains the service endpoints we want to route to.
        List<ServiceEndpoint> endpointList = new List<ServiceEndpoint>();

        foreach (string serverAddress in serviceAddresses)
        {
            // Set up our server binding(s) for each server.
            NetTcpBinding serverBinding = new NetTcpBinding(SecurityMode.None, true);
            serverBinding.SendTimeout = new TimeSpan(0, 1, 0);
            serverBinding.ReceiveTimeout = new TimeSpan(25, 0, 0);
            serverBinding.MaxReceivedMessageSize = int.MaxValue;
            serverBinding.MaxConnections = 1;
            serverBinding.ListenBacklog = int.MaxValue;
            serverBinding.ReliableSession.Enabled = true;
            serverBinding.ReliableSession.Ordered = true;
            serverBinding.ReliableSession.InactivityTimeout = new TimeSpan(15, 0, 0, 0);

            // Create the server endpoint the router will route messages to and from.
            ContractDescription contract = ContractDescription.GetContract(contractType);
            ServiceEndpoint server = new ServiceEndpoint(contract, serverBinding, new EndpointAddress(serverAddress));

            // Add the server to the list of endpoints.
            endpointList.Add(server);
        }

        // Create a new routing configuration object.
        RoutingConfiguration routingConfiguration = new RoutingConfiguration();

        // Add a MatchAll filter to the Router's filter table. Map it to the endpoint list defined earlier. When a message matches this filter, it will be sent to the endpoint contained in the list.
        routingConfiguration.FilterTable.Add(new MatchAllMessageFilter(), endpointList);

        // Attach the behavior to the service host.
        aggregatorHost.Description.Behaviors.Add(new RoutingBehavior(routingConfiguration));

        // Open the service host.
        aggregatorHost.Open();



        m_eventLog.WriteEntry(string.Format("Log aggregator service hosted at {0}.", routerAddress), EventLogEntryType.Information);

}

所以再一次......这就是我想要的：

CLIENT ---REQ---> ROUTER ---REQ---> SVC1
                         ---REQ---> SVC2

CLIENT <---CALLBACK1--- ROUTER <---CALLBACK1--- SVC1
       <---CALLBACK2---        <---CALLBACK2--- SVC2

这就是我现在得到的：

CLIENT ---REQ---> ROUTER ---REQ---> SVC1

CLIENT <---CALLBACK--- ROUTER <---CALLBACK--- SVC1

这是我错过的优先事项。我猜传入列表会自动生成优先级，因此您需要单独添加每个服务并指定其优先级： routingConfiguration.FilterTable.Add(new MatchAllMessageFilter(), new List { yourService }, 1);
