C# 3.5 - 跨网络连接命名管道 [英] C# 3.5 - Connecting named pipe across network

问题描述

在 C# 中通过网络设置命名管道的正确方法是什么?

What is the correct way to setup a named pipe in C# across a network?

目前我有两台机器，客户端"和服务器".

Currently I have two machines, 'client' and 'server'.

服务器以下列方式设置它的管道:

Server sets up its pipe in the following manner:

NamedPipeServerStream pipeServer = new NamedPipeServerStream(
    "pipe",
    PipeDirection.InOut,
    10,
    PipeTransmissionMode.Byte,
    PipeOptions.None)
pipeServer.WaitForConnection();
//... Read some data from the pipe

客户端通过以下方式建立连接:

The client sets up its connection in the following manner:

NamedPipeClientStream pipeClient = new NamedPipeClientStream(
    "server",
    "pipe",
    PipeDirection.InOut);
pipeClient.Connect(); //This line throws an exception
//... Write some data to the pipe

可以通过转到\server"在网络上访问server"机器.

The 'server' machine can be accessed on the network by going to "\server".

每当我运行该程序时，我都会收到一个 System.UnauthorizedAccessException，显示对路径的访问被拒绝".当我在本地机器上运行服务器和客户端并尝试连接到."时，代码工作正常.与客户.

Whenever I run the program, I get a System.UnauthorizedAccessException that says "Access to the path is denied." The code works fine when I run the server and client on my local machine and attempt to connect to "." with the client.

推荐答案

机器之间不能使用命名管道.

It is not possible to used named pipes between machines.
