C#中用NamedPipe進程間通信

本文只是一個測試例子，核心代碼是kernel32.dll中的一組windows api函數，這裡不深入研究，代碼都在codeproject上。

測試效果如下，可以做到aspx和給console app發送消息後得到反饋：

console app為服務器端代碼如下

using System;
using AppModule.InterProcessComm;
using AppModule.NamedPipes;
using System.Threading;
namespace Server
{
    class Program
    {
        //**c#中用namedpipe進程間通信
        //**組件代碼來自codeproject
        //**http://www.codeproject.com/KB/threads/dotnetnamedpipespart1.aspx
        //**下載上面鏈接中的代碼，編譯AppModule.InterProcessComm和AppModule.NamedPipes兩個dll
        //**引用這兩個dll到本例中，運行如下代碼作為服務器端測試
        //**測試代碼by jinjazz（因為原作者的兩個測試程序比較復雜，這裡簡化後供大家參考）
        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();
        }
    }
}

客戶端的aspx代碼如下

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("測試asdf"));
    }
    /// <summary>
    /// 測試namepiped客戶端
    /// </summary>
    /// <param name="request">發送命令</param>
    /// <returns>返回數據</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;
    }
}

測試環境為windows vista和windows2003
