使用命令行單聲道構建zeromq helloworld示例

Question

我正在嘗試使用C＃綁定爲zeromq構建helloworld示例。我已成功構建.Net庫（clrzmq.dll）。我正嘗試使用單聲道附帶的csharp編譯器構建單個csharp源代碼，構建命令行。

我已經包含下面的源文件的內容：

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

/** 
* Author: Randy Dryburgh 
* Email: me@rwd.im 
* License: This example code licensed under the MIT/X11 license. 
*/ 

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); 
       } 
      } 
     } 
    } 
} 

下面是一個命令行命令我使用和錯誤消息我得到。

oompah@localhost:~/work/dev/c++/3rdparty/zeromq/zguide/examples/C#$ mcs hwserver.cs.v1 -lib:/home/oompah/work/dev/c++/3rdparty/zeromq/clrzmq2/clrzmq/bin/Release/ -r:clrzmq.dll 
hwserver.cs.v1(20,53): error CS0234: The type or namespace name `REP' does not exist in the namespace `ZMQ'. Are you missing an assembly reference?

hwserver.cs.v1(26,28): error CS1615: Argument `#1' does not require `out' modifier. Consider removing `out' modifier 
Compilation failed: 5 error(s), 0 warnings 

我不知道爲什麼會有編譯什麼是表面上的「小事」 Hello World示例與指南提供的代碼，當如此多的錯誤。

zeromq的.Net程序集成功構建，所以我不明白爲什麼我得到上述錯誤（假設上面的代碼沒有錯誤） - 我該如何解決這個問題？

我在Ubuntu 10.0.4 LTS，64位上運行。

貌似例子有點過時的庫變得更好csharped;）我剛剛下載clrzmq檢查。試試這個版本：

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

/** 
* Author: Randy Dryburgh 
* Email: me@rwd.im 
* License: This example code licensed under the MIT/X11 license. 
*/ 

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); 
       } 
      } 
     } 
    } 
} 

舊版本後：

哪個版本的單聲道您使用的是？您可能有興趣調用gmcs或dmcs而不是mcs。

以下兩個部分：

namespace ZMQGuide 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      // ZMQ Context, server socket 
      using (Context context = new Context(1) 
      using (Socket socket = context.Socket(SocketType.REP)) 
      { 
       socket.Bind("tcp://*:5555"); 

       while (true) 
       { 
        // Wait for next request from client 
        string message = socket.Recv(Encoding.Unicode); 
        Console.WriteLine("Received request: {0}", message); 

        // Do Some 'work' 
        Thread.Sleep(1000); 

        // Send reply back to client 
        socket.Send("World", Encoding.Unicode); 
       } 
      } 
     } 
    } 
} 

namespace ZMQGuide 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      // ZMQ Context and client socket 
      using (Context context = new Context(1)) 
      using (Socket requester = context.Socket(SocketType.REQ)) 
      { 
       requester.Connect("tcp://localhost:5555"); 

       string request = "Hello"; 
       for (int requestNum = 0; requestNum < 10; requestNum++) 
       { 
        Console.WriteLine("Sending request {0}...", requestNum); 
        requester.Send(request, Encoding.Unicode); 

        string reply = requester.Recv(Encoding.Unicode); 
        Console.WriteLine("Received reply {0}: {1}", requestNum, reply); 
       } 
      } 
     } 
    } 
}
