进程通信——命名管道通信

 private static void WaitData()
    {
        using (NamedPipeServerStream pipeServer =
        new NamedPipeServerStream("testpipe", PipeDirection.InOut, 1))
        {
            try
            {
                pipeServer.WaitForConnection();
                pipeServer.ReadMode = PipeTransmissionMode.Byte;
                using (StreamReader sr = new StreamReader(pipeServer))
                {
                    string con = sr.ReadToEnd();
                    Console.WriteLine(con);
                }
            }
            catch (IOException e)
            {
                throw e;
            }
        }
    }
客户端代码

    private static void SendData()
    {
        try
        {
            using (NamedPipeClientStream pipeClient =
          new NamedPipeClientStream("localhost", "testpipe", PipeDirection.InOut, PipeOptions.None, TokenImpersonationLevel.None))
            {
                pipeClient.Connect();
                using (StreamWriter sw = new StreamWriter(pipeClient))
                {
                    sw.WriteLine("hahha");
                    sw.Flush();
                }
            }
        }
        catch (Exception ex)
        {
            throw ex;
        }

    }
