Question

我有一个用不同机器上运行的C＃编写的控制台应用程序系统。我使用MSMQ。

我的问题是，如何让我的控制台应用程序相互通信？

我问，因为我想创建一个新的控制台应用程序，可以被其他应用程序查询，以了解MSMQ中的消息数量。

编辑1：感谢您的回复和评论！关于要求，我估计可能大约10-50 /秒的查询

您需要使用管道来实现此目的：请参阅Named pipe and anonymous pipe

管道的工作原理如下：主机应用程序（启动控制台应用程序的应用程序）必须创建一个管道来捕获concole应用程序的std输出，另一个应用程序写入控制台应用程序的std输入。

我给你的链接中有很多代码示例

这里还有一个代码示例（使用现有的管道StandardInput和StandardOutput）：它启动一个cmd.exe控制台，但它是一个层：而不是实际的控制台......看看你自己：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Diagnostics;
using System.IO;
using System.Threading;

namespace ConsoleApplication1
{
    class Program
    {
        private static StreamReader reader;

        static void Main(string[] args)
        {
            Process cmd = new Process();

            cmd.StartInfo.FileName = "cmd.exe";
            cmd.StartInfo.RedirectStandardInput = true;
            cmd.StartInfo.RedirectStandardOutput = true;
            cmd.StartInfo.UseShellExecute = false;

            cmd.Start();

            reader = cmd.StandardOutput;
            StreamWriter writer = cmd.StandardInput;


            Thread t = new Thread(new ThreadStart(writingThread));

            t.Start();

            //Just write everything we type to the cmd.exe process
            while (true) writer.Write((char)Console.Read());

        }

        public static void writingThread()
        {
            //Just write everything cmd.exe writes back to our console
            while (true) Console.Write((char)reader.Read());
        }
    }
}

您可以通过端口连接（套接字）缓冲区替换StreamReader和StreamWriter来实现相同的结果，以便在两个进程之间进行远程通信 http://msdn.microsoft.com/en-us/library/system.net.sockets.socket.aspx

建议保护通信以最大限度地减少入侵可能性

以下是通过套接字进行通信的示例...现在这是在一个程序中运行但是所有内容都在不同的线程上，如果通信是在两台独立的机器上，它将起作用：服务器是控制它的人进程cmd.exe，客户端是查看器/编写器

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Diagnostics;

using System.Threading;

    class Program
    {
        private static StreamReader reader;
        private static StreamWriter writer;

        static void Main(string[] args)
        {
            //Server initialisation 

            Process cmdServer = new Process();

            cmdServer.StartInfo.FileName = "cmd.exe";
            cmdServer.StartInfo.RedirectStandardInput = true;
            cmdServer.StartInfo.RedirectStandardOutput = true;
            cmdServer.StartInfo.UseShellExecute = false;

            cmdServer.Start();

            reader = cmdServer.StandardOutput;
            writer = cmdServer.StandardInput;


            Thread t1 = new Thread(new ThreadStart(clientListener));
            t1.Start();
            Thread t2 = new Thread(new ThreadStart(clientWriter));
            t2.Start();
            Thread t3 = new Thread(new ThreadStart(serverListener));

可测试且可扩展 - 可以轻松更改为在计算机之间工作。

你有几个方法。使用WCF可以轻松实现“命名管道”。它很好，因为它非常可测试。

最佳性能您可以使用内存映射文件http://weblogs.asp.net/gunnarpeipman/archive/2009/06/21/net-framework-4-0-using-memory-mapped-files.aspx

他们有令人惊叹的表现。但是更难以测试。

最简单 - 如果您的流量非常低，则可以使用注册表。 C＃中的Regisrty类是线程安全且快速的。

Answer 3

WCF。 WCF，WCF，WCF，WCF。

不要费心重新发明轮子，只需使用WCF进行通信，让它担心细节（无论是使用管道还是其他机制）。
