IPC Mechanisms in C# - Usage and Best Practices

I have two diffenent process: A and B.

The process A wants to send to the process B some data (array of bytes, strings, structures, etc...). So suppose A need to send the following buffer:

var buffer = new byte[100].
SendToAnotherProcess(B, buffer);

And B need to receive this buffer:

byte[] buffer;
ReceiveFromAnotherProcess(A, out buffer);

What is the easiest solution to do this?

Answer 1

You can use Named Pipe. If it is C# 4.0 and above, you can also use Memory mapped file

Answer 2

There's a multitude of options. To name a few low-level IPC mechanisms:

• named pipes
• shared memory
• TCP/IP sockets

Also, there are some higher-level options:

• .NET Remoting
• WCF
