SocketIO4Net.Client

Project Description

SocketIO4Net.Client

Update as of 11/02/2013

 A develop branch is up at https://github.com/jstott/socketio4net/tree/develop for anyone looking to take an early peek.  Xhr-polling and websockets are working from the C# client.  Thank to the efforts from one of our users Nick, this feature is just about there!

Of particular interest, I'm looking for feedback on the .net 40 assembly types (client, PCL etc...) most interested in.  The plan is to release a both .net v4.0 & v4.5, using native .net websockets in v4.5 vs websocket4net currenlty in v4.0.

SocketI04net v4.0 is now leveraging the Microsoft.BCL.Async library (includes Microsoft.BCL.Build, Http packs) - please let me know if that create any additional issues.

Nuget packages are not available (yet), but after some additional testing and release notes will create a pre-release version for the latest code.

Please continue to leave discussions here, and if you have/see any issues with the latest develop code on github, please log there.

NuGet updated to v06.26

Project Description

SocketIO4Net.Client provides a .NET 4.0 C# client for Socket.IO.  It provides an overall interface similar to the client JavaScript experience, leveraging the WebSocket4Net project for an underlying websocket implementation.

My goal for this project is a simple & familiar experience for .net clients.  You know you want your .Net app to join in some of the fun, right?  Besides, all the cool kids are using Nodejs and Socket.IO these days anyway, give it a whirl.

This resulting signature is very similar to the socket.io javascript counterpart:

node.js / JavaScript client

socket.on('news', function (data) {
    console.log(data);
});

C# .net client

socket.On("news", (data) =>    {
    Console.WriteLine(data);
});

The all important - Sample / Demo code snippet 

Client socket;
public void Execute()
{
    Console.WriteLine("Starting TestSocketIOClient Example...");

    socket = new Client("http://127.0.0.1:3000/"); // url to nodejs 
    socket.Opened += SocketOpened;
    socket.Message += SocketMessage;
    socket.SocketConnectionClosed += SocketConnectionClosed;
    socket.Error += SocketError;
            
    // register for 'connect' event with io server
    socket.On("connect", (fn) =>
    {
        Console.WriteLine("
Connected event...
");
        Console.WriteLine("Emit Part object");

        // emit Json Serializable object, anonymous types, or strings
        Part newPart = new Part() 
        { PartNumber = "K4P2G324EC", Code = "DDR2", Level = 1 };
        socket.Emit("partInfo", newPart);
    });

    // register for 'update' events - message is a json 'Part' object
    socket.On("update", (data) =>
    {
        Console.WriteLine("recv [socket].[update] event");
        //Console.WriteLine("  raw message:      {0}", data.RawMessage);
        //Console.WriteLine("  string message:   {0}", data.MessageText);
        //Console.WriteLine("  json data string: {0}", data.Json.ToJsonString());
        //Console.WriteLine("  json raw:         {0}", data.Json.Args[0]);
                
        // cast message as Part - use type cast helper
        Part part = data.Json.GetFirstArgAs<Part>();
        Console.WriteLine(" Part Level:   {0}
", part.Level);
    });

    // make the socket.io connection
    socket.Connect();
}

Getting Started

Two ways to get started:

1. Download source code, compile, and run the included Test & Sample code and have a look around.
2. Install via Nuget – run the following command in the Package Manager Console >  Install-Package SocketIO4Net.Client

See the Documentation section for further details.
