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，這里不深入研究，代碼都在codePRoject上。

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

console app為服務器端代碼如下

view plaincopy to clipboardprint?
using System;  
using AppModule.InterProcessComm;  
using AppModule.NamedPipes;  
using System.Threading;  
namespace Server  
{  
    class Program  
    {

        //**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，這里簡化后供大家參考）

            ServerPipeConnection PipeConnection = new ServerPipeConnection("np-test-by-jinjazz", 512, 512, 5000, false);

客戶端的aspx代碼如下

view plaincopy to clipboardprint?
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;  
    }  
} 
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)
    {

    }
    /// <summary>

測試環境為windows Vista和windows2003
