c# - NetTcpBinding - 自托管 WCF - 无法连接客户端

Question

尝试获得 NetTcpBinding 的简单演示，以便将其扩展到另一个项目。

架构:2 个控制台应用程序(1 个主机/服务器，1 个客户端)和 1 个类型库项目。两个控制台应用程序都引用了类型库项目。

宿主应用:

class Program
{ 
    static void Main()
    {
        var netTcpBinding = new NetTcpBinding(SecurityMode.None)
        {
            PortSharingEnabled = true
        };

        var netTcpAdddress = new Uri("net.tcp://127.0.0.1:1234/HelloWorldService/");

        var tcpHost = new ServiceHost(typeof(HelloWorldService), netTcpAdddress);
        tcpHost.AddServiceEndpoint(typeof(IHelloWorld), netTcpBinding, "IHelloWorld");

        tcpHost.Open();
        Console.WriteLine($"tcpHost is {tcpHost.State}.  Press enter to close.");

        Console.ReadLine();
        tcpHost.Close();
    }
}


public class HelloWorldService : IHelloWorld
{
    public void HelloWorld()
    {
        Console.WriteLine("Hello World!");
    }

    public void WriteMe(string text)
    {
        Console.WriteLine($"WriteMe: {text}");
    }
}

客户端应用:

    static void Main()
    {
        Console.WriteLine("Press enter when the service is opened.");
        Console.ReadLine();


        var endPoint = new EndpointAddress("net.tcp://127.0.0.1:1234/HelloWorldService/");
        var binding = new NetTcpBinding ();
        var channel = new ChannelFactory<IHelloWorld>(binding, endPoint);
        var client = channel.CreateChannel();

        try
        {
            Console.WriteLine("Invoking HelloWorld on TcpService.");
            client.HelloWorld();
            Console.WriteLine("Successful.");
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Exception: {ex.Message}");
        }

        Console.WriteLine("Press enter to quit.");
        Console.ReadLine();
    }

类型库:

[ServiceContract]
public interface IHelloWorld
{
    [OperationContract]
    void HelloWorld();

    [OperationContract]
    void WriteMe(string text);
}

我相信我已经安装并运行了所有必要的服务:

显然，我正在尝试在运行时进行所有配置。

我一直在客户端收到此错误消息:

在 TcpService 上调用 HelloWorld。

Exception: There was no endpoint listening at net.tcp://127.0.0.1:1234/HelloWorldService/ that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. Press enter to quit.

我是否漏掉了一些明显的东西？

Answer 1

您的服务在以下地址公开端点:

net.tcp://127.0.0.1:1234/HelloWorldService/IHelloWorld

但是您的客户端正在连接到:

net.tcp://127.0.0.1:1234/HelloWorldService/

您还需要将客户端 NetTcpBinding SecurityMode 设置为与服务器相同(None)。
