I have quite a few gripes with clrzmq and clrzmq2, and NZMQ is incomplete in
several areas, so over a few weekends this past month I've written a new C# API
for ZeroMQ based on the 2.0.10 release of zmq.h.
ZeroMQ Interop v0.8.190.10354 (beta)
http://zeromq.codeplex.com
* Feature-complete
* MIT licensed
* Targeted at both Microsoft and Mono .NET 2.0 CLRs (though it does require a
3.5 compatible compiler, basically for lambda syntax)
* Includes binaries for both 32 and 64bit platforms (without any #ifdefs)
Here's an example using Pub/Sub sockets-
> // Set up a publisher.
>
> var publisher = new ZmqPublishSocket {
> Identity = Guid.NewGuid().ToByteArray(),
> RecoverySeconds = 10
> };
>
> publisher.Bind( address: "tcp://127.0.0.1:9292" );
>
> // Set up a subscriber.
>
> var subscriber = new ZmqSubscribeSocket();
>
> subscriber.Connect( address: "tcp://127.0.0.1:9292" );
>
> subscriber.Subscribe( prefix: "" ); // subscribe to all messages
>
> // Add a handler to the subscriber's OnReceive event
>
> subscriber.OnReceive += () => {
>
> String message;
> subscriber.Receive( out message, nonblocking: true );
>
> Console.WriteLine( message );
> };
>
> // Publish a message to all subscribers.
>
> publisher.Send( "Hello world!" );
A few things that make this sample stand out from the other two ZeroMQ C#
libraries-
* There's no need to manage your ZeroMQ context; it's taken care of on a
per-AppDomain basis using refcounting.
* There is no "message" object because it provides no added benefit in C#.
Messages are simply Byte[]s, with overloads throughout the API that accept
Strings.
* First-class support for .NET events programming, implemented using zmq_poll()
(but that's completely transparent to the user).
I'd love some feedback. I'm just starting to use it in a project I'm working
on, and so far it all seems to be working smoothly and at high throughput, but
I'm releasing it as "beta" because I don't feel that it has enough real-world
experience yet.
