wcf 請考慮增加操作超時

發送到 net.tcp://192.168.1.18:8732/CallbackService 的請求操作在配置的超時(00:00:59.9879994)內未收到回復。

分配給此操作的時間可能已經是更長超時的一部分。這可能由於服務仍在處理操作或服務無法發送回復消息。

請考慮增加操作超時(將通道/代理轉換為 IContextChannel 並設置 OperationTimeout 屬性)並確保服務能夠連接到客戶端。

 

網上找了很多資料，都無法解決我的問題。

 

  INotificationServices proxy;
            DuplexChannelFactory<INotificationServices> channelFactory;
            const string wsDualHttpBinding = "WSDualHttpBinding_INotificationServices";
            const string netTcpBinding = "NetTcpBinding_INotificationServices";
            InstanceContext context = new InstanceContext(new NotificationServiceCallBack());

            channelFactory = new DuplexChannelFactory<INotificationServices>(context, wsDualHttpBinding);
            proxy = channelFactory.CreateChannel();
            proxy.SendNotification("Are u ready?");

            
            channelFactory = new DuplexChannelFactory<INotificationServices>(context, netTcpBinding);
            proxy = channelFactory.CreateChannel();
            proxy.SendNotification("Are u ready?");

            Console.WriteLine("Press Enter to terminate the client");
            Console.ReadLine();

客戶端配置

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <client>
            <endpoint address="http://192.168.1.18:8888/CallbackService"
                binding="wsDualHttpBinding" bindingConfiguration="" contract="Library.INotificationServices"
                name="WSDualHttpBinding_INotificationServices" />
            <endpoint address="net.Tcp://192.168.1.18:8732/CallbackService"
                binding="netTcpBinding" bindingConfiguration="" contract="Library.INotificationServices"
                name="NetTcpBinding_INotificationServices" />
        </client>
    </system.serviceModel>
</configuration>

 

問題在於

context = new InstanceContext(new NotificationServiceCallBack());

這個是無法共用的。

 

第二個代理必須重新new一個新的InstanceContext對象，才能夠正常查詢
