C#如何调用ZeroMQ

自己写的C#调用zeromq，希望有人能够用得着，其它的应该可以借用下

主要还是下面这部分

应答模式请求端    建立Socket

void* context_req = libzmq.zmq_ctx_new();
Data.socket_req = libzmq.zmq_socket(context_req, (int)Socket_Types.ZMQ_REQ);
int result = libzmq.zmq_connect(Data.socket_req, Data.Instance.Config.ServerIP + ":" + Data.Instance.Config.Req_Port);

发送命令以及接受

	/// 

        /// 发送命令
        /// 
        /// 命令
        public unsafe static void send_cmd(string cmd)
        {
            byte[] byte_send = Encoding.Default.GetBytes(cmd);
            zmq_msg_t* msg1 = stackalloc zmq_msg_t[1];
            libzmq.zmq_msg_init_size(msg1, byte_send.Length);
            void* ptr1 = libzmq.zmq_msg_data(msg1);
            Marshal.Copy(byte_send, 0, (IntPtr)ptr1, byte_send.Length);
            int result = libzmq.zmq_msg_send(msg1, Data.socket_req, 0);

            zmq_msg_t* msg = stackalloc zmq_msg_t[1];
            int rec_ionti = libzmq.zmq_msg_init(msg);
            int size = libzmq.zmq_msg_recv(msg, Data.socket_req, 0);
            void* ptr = libzmq.zmq_msg_data(msg);
            string str = Marshal.PtrToStringAnsi((IntPtr)ptr);
            libzmq.zmq_msg_close(msg);          
        }

广播模式接受端

void* context = libzmq.zmq_ctx_new();
void* socket = libzmq.zmq_socket(context, 2);
result = libzmq.zmq_connect(socket, Data.Instance.Config.ServerIP + ":" + Data.Instance.Config.Sub_Port);
int rc = libzmq.zmq_setsockopt(socket, (int)Socket_Options.ZMQ_SUBSCRIBE, (void*)null, 0);
zmq_msg_t* msg = stackalloc zmq_msg_t[1];
int rec_ionti = libzmq.zmq_msg_init(msg);
int size = libzmq.zmq_msg_recv(msg, socket, 0);
void* ptr = libzmq.zmq_msg_data(msg);
string str = Marshal.PtrToStringAnsi((IntPtr)ptr).Substring(0, size);
