如何使用ZeroMQ将消息从C#客户端发送到C++服务器

using System;
using NetMQ;
using NetMQ.Sockets;

class Program
{
    static void Main(string[] args)
    {
        using (var client = new RequestSocket())
        {
            client.Connect("tcp://localhost:5555"); // 替换为C++服务器的地址和端口

            string message = "Hello from C# client";
            client.SendFrame(message);

            string response = client.ReceiveFrameString();
            Console.WriteLine("Received response from C++ server: " + response);
        }
    }
}

#include <iostream>
#include <string>
#include <zmq.hpp>

int main()
{
    zmq::context_t context(1);
    zmq::socket_t server(context, ZMQ_REP);
    server.bind("tcp://*:5555"); // 绑定到指定端口

    while (true)
    {
        zmq::message_t request;
        server.recv(&request);

        std::string message = std::string(static_cast<char*>(request.data()), request.size());
        std::cout << "Received message from C# client: " << message << std::endl;

        std::string response = "Hello from C++ server";
        zmq::message_t reply(response.size());
        memcpy(reply.data(), response.data(), response.size());
        server.send(reply);
    }

    return 0;
}
