C#中用NamedPipe进程间通信

本文只是一个测试例子，核心代码是kernel32.dll中的一组windows api函数，这里不深入研究，代码都在codeproject上。

测试效果如下，可以做到aspx和给console app发送消息后得到反馈：

console app为服务器端代码如下

 

using System;
using AppModule.InterProcessComm;
using AppModule.NamedPipes;
using System.Threading;
namespace Server
{
    class Program
    {
        //**c#中用namedpipe进程间通信
        //**组件代码来自codeproject
        //**http://www.codeproject.com/KB/threads/dotnetnamedpipespart1.aspx
        //**下载上面链接中的代码，编译AppModule.InterProcessComm和AppModule.NamedPipes两个dll
        //**引用这两个dll到本例中，运行如下代码作为服务器端测试
        //**测试代码by jinjazz（因为原作者的两个测试程序比较复杂，这里简化后供大家参考）
        static void Main(string[] args)
        {
            ServerPipeConnection PipeConnection = new ServerPipeConnection("np-test-by-jinjazz", 512, 512, 5000, false);
            Console.WriteLine("listening..");
            while (true)
            {
                try
                {
                    PipeConnection.Disconnect();
                    PipeConnection.Connect();
                    string request = PipeConnection.Read();
                    if (!string.IsNullOrEmpty(request))
                    {
                        Console.WriteLine("get:" + request);
                        PipeConnection.Write("get:" + request);
                        if (request.ToLower() == "break") break;
                    }
                }
                catch (Exception ex)
                {
                    Console.WriteLine(ex.Message);
                    break;
                }
            }
            PipeConnection.Dispose();
            Console.Write("press any key to exit..");
            Console.Read();
        }
    }
}

using System; using AppModule.InterProcessComm; using AppModule.NamedPipes; using System.Threading; namespace Server { class Program { //**c#中用namedpipe进程间通信 //**组件代码来自codeproject //**http://www.codeproject.com/KB/threads/dotnetnamedpipespart1.aspx //**下载上面链接中的代码，编译AppModule.InterProcessComm和AppModule.NamedPipes两个dll //**引用这两个dll到本例中，运行如下代码作为服务器端测试 //**测试代码by jinjazz（因为原作者的两个测试程序比较复杂，这里简化后供大家参考） static void Main(string[] args) { ServerPipeConnection PipeConnection = new ServerPipeConnection("np-test-by-jinjazz", 512, 512, 5000, false); Console.WriteLine("listening.."); while (true) { try { PipeConnection.Disconnect(); PipeConnection.Connect(); string request = PipeConnection.Read(); if (!string.IsNullOrEmpty(request)) { Console.WriteLine("get:" + request); PipeConnection.Write("get:" + request); if (request.ToLower() == "break") break; } } catch (Exception ex) { Console.WriteLine(ex.Message); break; } } PipeConnection.Dispose(); Console.Write("press any key to exit.."); Console.Read(); } } }

 

 

客户端的aspx代码如下

 

using System;
using System.Web;
using AppModule.InterProcessComm;
using AppModule.NamedPipes;
public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        Response.Write(SendRequest("测试asdf"));
    }
    /// <summary>
    /// 测试namepiped客户端
    /// </summary>
    /// <param name="request">发送命令</param>
    /// <returns>返回数据</returns>
    string SendRequest(string request)
    {
        string response="";
        IInterProcessConnection clientConnection = null;
        try
        {
            clientConnection = new ClientPipeConnection("np-test-by-jinjazz", ".");
            clientConnection.Connect();
            clientConnection.Write(request);
            response=clientConnection.Read();
            clientConnection.Close();
        }
        catch (Exception ex)
        {
            clientConnection.Dispose();
            response = ex.Message;
        }
        return response;
    }
}

using System; using System.Web; using AppModule.InterProcessComm; using AppModule.NamedPipes; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Response.Write(SendRequest("测试asdf")); } /// <summary> /// 测试namepiped客户端 /// </summary> /// <param name="request">发送命令</param> /// <returns>返回数据</returns> string SendRequest(string request) { string response=""; IInterProcessConnection clientConnection = null; try { clientConnection = new ClientPipeConnection("np-test-by-jinjazz", "."); clientConnection.Connect(); clientConnection.Write(request); response=clientConnection.Read(); clientConnection.Close(); } catch (Exception ex) { clientConnection.Dispose(); response = ex.Message; } return response; } }

 

 

测试环境为windows vista和windows2003
