[英]Building zeromq helloworld example with command line mono
我正在嘗試使用C#綁定為zeromq構建一個helloworld示例。 我成功構建了.Net庫(clrzmq.dll)。 我正在嘗試使用mono附帶的csharp編譯器構建單個csharp源,形成命令行。
我已經包含了以下源文件的內容:
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);
}
}
}
}
}
這是我使用的命令行命令和我得到的錯誤消息。

我不確定在編譯表面上是什么時會出現這么多錯誤,這是指南提供的“瑣碎的”hello world示例代碼。
zeromq的.Net程序集成功構建,所以我不明白為什么我得到上面的錯誤(假設上面的代碼沒有任何問題) - 我該如何解決這個問題?
我正在運行Ubuntu 10.0.4 LTS,64位。

這兩個部分:
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);
}
}
}
}
}
看起來示例有點過時,因為庫得到了更好的csharped;)我剛剛下載了clrzmq來檢查。 試試這個版本:
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);
}
}
}
}
}
老版本的帖子:
您使用哪種單聲道版本? 您可能有興趣調用gmcs或dmcs而不是mcs。
