Windows 服务中使用 App.Config 的 WCF 命名管道

我烦了。好的，这是错误。

net.pipe://localhost/MyIpcAppToService 上没有侦听端点可以接受该消息。这通常是由不正确的地址或 SOAP 操作引起的。有关更多详细信息，请参阅 InnerException（如果存在）。

我终于让 App.Config 文件正常工作了，至少没有抱怨。

我曾经有过：

<endpoint address="http://localhost:8733/MyIpcAppToService" ...

并在 Windows 服务中OnStart() event:

（从本问题帖子开始，以下代码现已被注释掉，因为App.config文件应该启动named.pipe。）

public Boolean CreatePipeServer()
{
    string eventText = $"My Service: CommAppToService::CreatePipeServer(IPC App to Service){Environment.NewLine}";
    try
    {
        if (null != this.ServiceParent.HostIpcAppToService)
            this.ServiceParent.HostIpcAppToService = null;

        string pipeBaseAddress = @"net.pipe://localhost/MyIpcAppToService";
        this.ServiceParent.HostIpcAppToService = new ServiceHost(typeof(IpcAppToService), new Uri(pipeBaseAddress));
        NetNamedPipeBinding pipeBinding = new NetNamedPipeBinding()
        {
            //ReceiveTimeout = new TimeSpan(0, 0, 0, 0, Constants.My_TimeoutMsSendReceive),
            //SendTimeout = new TimeSpan(0, 0, 0, 0, Constants.My_TimeoutMsSendReceive),
        };
        this.ServiceParent.HostIpcAppToService.AddServiceEndpoint(typeof(IIpcAppToService), pipeBinding, "MyIpcAppToService");
        this.ServiceParent.HostIpcAppToService.UnknownMessageReceived += HostIpcAppServer_UnknownMessageReceived;
        this.ServiceParent.HostIpcAppToService.Faulted += HostIpcAppServer_Faulted;
        this.ServiceParent.HostIpcAppToService.Closing += HostIpcAppServer_Closing;
        this.ServiceParent.HostIpcAppToService.Closed += HostIpcAppServer_Closed;

        this.IpcAppToService = new IpcAppToService();
        this.IpcAppToService.ApplyDispatchBehavior(this.ServiceParent.HostIpcAppToService);
        this.IpcAppToService.Validate(this.ServiceParent.HostIpcAppToService);
        this.ServiceParent.HostIpcAppToService.Open();

        return true;
    }

我读到该服务将自动启动放置在App.Config文件，确实是MyExeName.exe.config文件。我不断查看代码，发现它几乎相同，所以我替换了http:// with net.pipe://.

可悲的是，旧代码、新代码、中间代码，什么都没有。我不断收到同样的错误。

我使用以下命令从桌面应用程序连接到该服务。

public static Boolean ConnectToService()
{
    try
    {
        var callback = new IpcCallbackAppToService();
        var context = new InstanceContext(callback);
        var pipeFactory = new DuplexChannelFactory<IIpcAppToService>(context, new NetNamedPipeBinding(), new EndpointAddress("net.pipe://localhost/MyIpcAppToService"));
        Program.HostIpcAppToService = pipeFactory.CreateChannel();
        Program.HostIpcAppToService.Connect();
        CommAppToService.IsPipeAppToService = true;

        return true;
    }

    catch (Exception ex)
    {
        // Log the exception.
        Errors.LogException(ex);
    }

    return false;
}

不管它的价值如何，这里是：

界面

[ServiceContract(SessionMode = SessionMode.Allowed, CallbackContract = typeof(IIpcCallbackAppToService))]
public interface IIpcAppToService
{
    [OperationContract(IsOneWay = false)]
    [FaultContractAttribute(typeof(IpcAppToServiceFault))]
    UInt16 GetServiceId();

    ...
}

Service:

[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
public class IpcAppToService : IIpcAppToService, IErrorHandler
{
    public static IIpcCallbackAppToService Callback { get; set; } = null;

    public void OpenCallback()
    {
        IpcAppToService.Callback = OperationContext.Current.GetCallbackChannel<IIpcCallbackAppToService>();
    }

    public void CloseCallback()
    {
        IpcAppToService.Callback = null;
    }

    public void SendMessage(string message)
    {
        //MessageBox.Show(message);
    }

    public UInt16 GetServiceId()
    {
        return Constants.My_Id_AppToService;
    }

    ...
}

内部异常从我的桌面 WinForms 应用程序 （注意，除了这个之外，没有更多的内部异常。）：

“在本地计算机上找不到管道端点 'net.pipe://localhost/MyIpcAppToService'。”

为什么我总是看到此错误？

第一个答案后更新

我想要采取的方向与答案相反，但相同，即服务从App.config和client使用 C# 代码。

可悲的是，我仍然遇到同样的错误。

修改服务器端 App.config

修改后的客户端 C# 代码：

var callback = new IpcCallbackAppToService();
InstanceContext context = new InstanceContext(callback);
NetNamedPipeBinding binding = new NetNamedPipeBinding();
binding.Security.Mode = NetNamedPipeSecurityMode.None;
EndpointAddress endpointAddress = new EndpointAddress("net.pipe://localhost/MyIpcAppToService");
var pipeFactory = new DuplexChannelFactory<IIpcAppToService>(context, binding, endpointAddress);
Program.HostIpcAppToService = pipeFactory.CreateChannel();
Program.HostIpcAppToService.Connect();
CommAppToService.IsPipeAppToService = true;

该服务不会引发我可以检测到的异常，因为 EventViewer 是干净的，只有 OnStart() 成功完成消息。我知道系统处理App.config文件，就像之前我遇到错误时一样，Windows Event Viewer会一直抱怨，但不会了。

以下是我使用的一些 Microsoft 文档：

网络命名管道绑定 https://learn.microsoft.com/en-us/dotnet/framework/wcf/samples/netnamedpipebinding

网络命名管道绑定 2 https://learn.microsoft.com/en-us/dotnet/framework/configure-apps/file-schema/wcf/netnamedpipebinding

我确实尝试过IO Ninja https://ioninja.com/，但指定\\.\pipe\MyIpcToService for File Stream, Pipe Listener, and Pipe Monitor，但是即使当我尝试使用 WinForms 桌面应用程序进行连接时，那里也没有显示任何内容，然后抛出 no pipeline Listenerfound 异常。

可能是什么问题？

<endpoint address="net.pipe://localhost/MyIpcAppToService" binding="wsDualHttpBinding" bindingConfiguration="MyAppToServiceEndpointBinding" contract="MyIpc.IIpcAppToService"/>

确保服务地址与绑定类型采用相同的形式（传输协议）。

• TCP(net.tcp://localhost:8000/myservice) NetTcpBinding
• IPC(net.pipe://localhost/mypipe) NetNamedPipeBinding

• Http/Https(http://localhost:8000/myservice http://localhost:8000/myservice)
  Wshttp绑定、Wsdualhttp绑定、基本http绑定

• WebSocket(ws://localhost:3434) Nethttp绑定

• MSMQ(net.msmq://localhost/private/myservice) NetMsmqBinding

我们应该使用 NetnamedPipeBinding 作为服务地址。请参考我的例子。

    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        string GetData(int value);
}
    public class Service1 : IService1
    {
        public string GetData(int value)
        {
            return string.Format("You entered: {0}", value);
        }
}
