c# - 使用命令行单声道构建 zeromq helloworld 示例

Question

我正在尝试使用 C# 绑定(bind)为 zeromq 构建一个 helloworld 示例。我已成功构建 .Net 库 (clrzmq.dll)。我正在尝试构建单个 csharp 源代码，形成命令行，使用单声道附带的 csharp 编译器。

我在下面包含了源文件的内容:

using System;
using System.Collections.Generic;
using System.Threading;
using System.Text;

 */

namespace Examples {
    class hwserver {
        static void Main(string[] args) {
            // allocate a buffer
            byte[] zmq_buffer = new byte[1024];

            //  Prepare our context and socket
            ZMQ.Context context = new ZMQ.Context(1);
            ZMQ.Socket  socket = context.Socket(ZMQ.REP);
            socket.Bind("tcp://*:5555");

            while (true) {
                try {
                    //  Wait for next request from client
                    socket.Recv(out zmq_buffer);
                    string request = Encoding.ASCII.GetString(zmq_buffer);

                    // log that we got one
                    Console.WriteLine("Received request: [%s]", request);
                    //  Do some 'work'
                    Thread.Sleep(1);

                    //  Send reply back to client
                    socket.Send(Encoding.ASCII.GetBytes("World".ToCharArray()));

                } catch (ZMQ.Exception z) {
                    // report the exception
                    Console.WriteLine("ZMQ Exception occurred : {0}", z.Message);
                }
            }
        }
    }
}

这是我使用的命令行命令和我得到的错误消息。

我不确定为什么在编译指南提供的表面上“微不足道”的 hello world 示例代码时会出现这么多错误。

zeromq 的 .Net 程序集已成功构建，所以我不明白为什么会出现上述错误(假设上面的代码没有任何问题)- 我该如何解决这个问题？

我在 64 位 Ubuntu 10.0.4 LTS 上运行。

看起来示例有点过时，因为库得到了更好的锐化；)我刚刚下载了 clrzmq 进行检查。试试这个版本:

using System;
using System.Collections.Generic;
using System.Threading;
using System.Text;

/**

 */

namespace Examples {
    class hwserver {
        static void Main(string[] args) {
            // allocate a buffer
            byte[] zmq_buffer = new byte[1024];

            //  Prepare our context and socket
            ZMQ.Context context = new ZMQ.Context(1);
            ZMQ.Socket  socket = context.Socket(ZMQ.SocketType.REP);
            socket.Bind("tcp://*:5555");

            while (true) {
                try {
                    //  Wait for next request from client
                    zmq_buffer = socket.Recv();
                    string request = Encoding.ASCII.GetString(zmq_buffer);

                    // log that we got one
                    Console.WriteLine("Received request: [{0}]", request);
                    //  Do some 'work'
                    Thread.Sleep(1);

                    //  Send reply back to client
                    socket.Send(Encoding.ASCII.GetBytes("World".ToCharArray()));

                } catch (ZMQ.Exception z) {
                    // report the exception
                    Console.WriteLine("ZMQ Exception occurred : {0}", z.Message);
                }
            }
        }
    }
}

帖子的旧版本:

您使用的是哪个单声道版本？您可能对调用 gmcs 或 dmcs 而不是 mcs 感兴趣。
