Question

我很沮丧。好的，这是错误。

在net.pipe：// localhost / MyIpcAppToService上没有侦听终结点的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，请参见InnerException（如果存在）。

我终于使App.Config文件正常运行，至少没有任何抱怨。

我曾经有过：

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

，并在Windows服务OnStart()事件中：

（此问题后，以下代码已注释掉，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;
    }

我了解到该服务将自动启动放置在App.Config文件（实际上是MyExeName.exe.config文件）中的服务。我不断查看代码，发现它们几乎相同，因此我将http://替换为net.pipe://。

可悲的是，旧代码，新代码，介于两者之间的代码，什么都没有。我一直收到同样的错误。

我使用以下内容从桌面应用程序连接到服务。

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;
}

对于它的价值，这里是：

接口

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

    ...
}

服务：

[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;
    }

    ...
}

我的桌面WinForms应用程序中的

内部异常 （请注意，没有比这更多的内部例外了。）：

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

为什么我继续看到此错误？

在第一个答案后更新

我要采取的方向与答案相反，但还是一样，即服务以App.config开始，而client使用C＃代码。

遗憾的是，我仍然遇到相同的错误。

修订的客户端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;

由于EventViewer是干净的，因此该服务不会抛出任何可以检测到的异常，仅显示OnStart（）成功完成的消息。我知道系统会处理App.config文件，就像以前遇到错误时一样，Windows Event Viewer会一直抱怨，但现在不再。

以下是我使用的一些Microsoft文档：

netNamedPipeBinding

netNamedPipeBinding2

我确实尝试过IO Ninja，但是为\\.\pipe\MyIpcToService，File Stream和Pipe Listener指定了Pipe Monitor，但是即使我尝试连接也没有显示任何内容使用我的WinForms桌面应用程序，该应用程序随后会抛出“找不到管道侦听器”异常。

可能是什么问题？

Answer 1

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

确保服务地址的格式（绑定协议）与绑定类型相同。

TCP（net.tcp：// localhost：8000 / myservice）NetTcpBinding
IPC（net.pipe：// localhost / mypipe）NetNamedPipeBinding
Http / Https（http://localhost:8000/myservice）
Wshttpbinding，Wsdualhttpbinding，basichttpbinding
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。
