服务端代码：

//创建服务端，管道实例
NamedPipeServerStream serverStream = new NamedPipeServerStream("test2PIPE",
    PipeDirection.InOut,
    1,
    PipeTransmissionMode.Message,
    PipeOptions.Asynchronous);
private void Form1_Load(object sender, EventArgs e)
{
    //启用线程接收消息
    ThreadPool.QueueUserWorkItem(delegate
    {
        serverStream.BeginWaitForConnection((o) =>
        {
            NamedPipeServerStream server = (NamedPipeServerStream)o.AsyncState;
            server.EndWaitForConnection(o);
            StreamReader sr = new StreamReader(server);
            StreamWriter sw = new StreamWriter(server);
            string result = null;
            string clientName = server.GetImpersonationUserName();
            while (true)
            {
                result = sr.ReadLine();
                if (result == null || result == "bye")
                    break;
                this.Invoke((MethodInvoker)delegate
                {
                    listBox1.Items.Add(clientName + ":" + result);
                });
            }
        }, serverStream);
    });

}

客户端代码：

        //创建客户端连接实例
        NamedPipeClientStream clientStream = new NamedPipeClientStream("127.0.0.1",
            "test2PIPE",
            PipeDirection.InOut, PipeOptions.Asynchronous,
            System.Security.Principal.TokenImpersonationLevel.None
            );
        StreamWriter sw = null;
        private void Form1_Load(object sender, EventArgs e)
        {
            //连接管道
            clientStream.Connect();
            sw = new StreamWriter(clientStream);
            sw.AutoFlush = true;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            //向管道中写入内容
            sw.WriteLine(richTextBox1.Text);
        }
