我试图建立一个命名管道（2方式）之间的Python 2.7和C＃应用程序。它适用于字节模式，但是当我在python服务器端更改消息模式时，C＃客户端声称它仍然是字节模式。命名管道之间的Python 2.7和C＃使用消息模式
这里是我的Python代码：
import win32pipe, win32file
p = win32pipe.CreateNamedPipe("\\\\.\\pipe\\test_pipe",
win32pipe.PIPE_ACCESS_DUPLEX,
win32pipe.PIPE_TYPE_MESSAGE|win32pipe.PIPE_READMODE_MESSAGE | win32pipe.PIPE_WAIT,
1, 65536, 65536,300,None)
print("Waiting for connection");
win32pipe.ConnectNamedPipe(p, None)
print("Client has connected")
win32file.WriteFile(p, "TestMessage".encode('utf-8'))
p.close()
我C＃-Code：
class Program
{
static void Main(string[] args)
{
using (NamedPipeClientStream clientStream = new NamedPipeClientStream(".", "test_pipe", PipeDirection.InOut))
{
clientStream.Connect();
Console.WriteLine("Connected");
string inMessage = ProcessSingleReceivedMessage(clientStream);
Console.WriteLine("in Message " + inMessage);
}
Console.ReadLine();
}
private static string ProcessSingleReceivedMessage(NamedPipeClientStream namedPipeClient)
{
Console.WriteLine("Transmission mode: " + namedPipeClient.TransmissionMode);
StringBuilder messageBuilder = new StringBuilder();
string messageChunk = string.Empty;
byte[] messageBuffer = new byte[5];
do
{
namedPipeClient.Read(messageBuffer, 0, messageBuffer.Length);
messageChunk = Encoding.UTF8.GetString(messageBuffer);
messageBuilder.Append(messageChunk);
messageBuffer = new byte[messageBuffer.Length];
}
while (!namedPipeClient.IsMessageComplete);
return messageBuilder.ToString();
}}
为简化起见，我只贴在Python到C＃中的传输，因为这里的错误出现在这里。由于某种原因，c＃客户端认为传输是Byte，因此发生InvalidOperationException异常，说“ReadMode不是PipeTransmissionMode.Message。”我做错了什么。
