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。http://www.codeproject.com/KB/threads/dotnetnamedpipespart1.aspx
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(); } }}
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; }}
测试环境为windows vista和windows2003
