在Python中创建named pipe：

import os
import time

pipe = "\\\\.\\pipe\\my_pipe"

try:
    os.mkfifo(pipe)
except OSError:
    pass

fifo = open(pipe, 'wb')

在C#中创建named pipe：

using System.IO.Pipes;

string pipeName = "my_pipe";
NamedPipeServerStream pipeServer = new NamedPipeServerStream(pipeName, PipeDirection.InOut);
pipeServer.WaitForConnection();

在Python中通过管道发送数据：

data = b"Hello, C#!"
fifo.write(data)
fifo.flush()

在C#中通过管道接收数据：

byte[] buffer = new byte[256];
int bytesRead = pipeServer.Read(buffer, 0, buffer.Length);
string message = Encoding.ASCII.GetString(buffer, 0, bytesRead);
