What is the best way for two programs on the same machine to communicate with each other

Question

I need to pass some data (integers) from one (C++) program to another (C#). What is the fastest way to do this?

PS: OS: Windows XP

Answer 1

My personal preference for this, given that you're using C++ and C# both, and it's on the same system, would be to use Pipes.

They work very well from native code (C++) as well as from C# via NamedPipeClientStream and NamedPipeServerStream .

However, there are other options for Interprocess Communication , any of which would work.

Answer 2

共享内存将是最快的，但命名管道也非常快，也更容易使用。

Answer 3

Check out this article for a run-down of the available options. Your best bet is probably a pipe .

Answer 4

Using files would be the simplest way. If you need the speed, then network sockets may be a good option.

Answer 5

mailslots can be used if you're communication is one-way and your messages are small. Otherwise I'd recommend using named pipes (as others have recommended).

here's something on mailslots

All IPC mechanisms

Answer 6

如果它是有用的，如果这是进程间通信并不重要（如果你需要的功能可以形成一个使用或类似的DLL），你可以使用公共语言运行时进行互操作。

Answer 7

My recommendation would be Sockets or RPC. I'm not familiar with pipes, but it seems to be a popular option too.
