C#使用命名管道Pipe进行进程通信实例详解

1.新建解决方案NamedPipeExample 新建两个项目：Client和Server，两者的输出类型均为“Windows 应用程序”。整个程序的结构如下图所示。

此Form1为Client的窗体，如下图所示。

后端代码，如下。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

using System.IO;
using System.IO.Pipes;
using System.Security.Principal;

namespace Client
{
  public partial class Form1 : Form
  {
    NamedPipeClientStream pipeClient =
      new NamedPipeClientStream("localhost", "testpipe", PipeDirection.InOut, PipeOptions.Asynchronous, TokenImpersonationLevel.None);
    StreamWriter sw = null;
    public Form1()
    {
      InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
      try
      {
 pipeClient.Connect(5000);
 sw = new StreamWriter(pipeClient);
 sw.AutoFlush = true;
      }
      catch (Exception ex)
      {
 MessageBox.Show("连接建立失败，请确保服务端程序已经被打开。");
 this.Close();
      }
    }

    private void btnSend_Click(object sender, EventArgs e)
    {
      if (sw != null)
      {
 sw.WriteLine(this.txtMessage.Text);
      }
      else
      {
 MessageBox.Show("未建立连接，不能发送消息。");
      }
    }
  }
}

此Form1为Server的窗体，如下图所示

后端代码，如下。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.IO.Pipes;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace Server
{
  public partial class Form1 : Form
  {
    NamedPipeServerStream pipeServer =
      new NamedPipeServerStream("testpipe", PipeDirection.InOut, 1, PipeTransmissionMode.Message, PipeOptions.Asynchronous);
    public Form1()
    {
      InitializeComponent();
    }

    private void textBox1_TextChanged(object sender, EventArgs e)
    {

    }

    private void Form1_Load(object sender, EventArgs e)
    {
      ThreadPool.QueueUserWorkItem(delegate
      {
 pipeServer.BeginWaitForConnection((o) =>
 {
   NamedPipeServerStream pServer = (NamedPipeServerStream)o.AsyncState;
   pServer.EndWaitForConnection(o);
   StreamReader sr = new StreamReader(pServer);
   while (true)
   {
     this.Invoke((MethodInvoker)delegate { lsvMessage.Text = sr.ReadLine(); });

   }
 }, pipeServer);
      });
    }

    private void maskedTextBox1_MaskInputRejected(object sender, MaskInputRejectedEventArgs e)
    {

    }
  }
}

先运行Server再运行Client
