SocketIOClient.NetFx 1.0.0.1

Socket.IO-client for .NET

An elegant socket.io client for .NET

How to use

If your TargetFramework is .NET Framework and it runs on Windows7/Windows Server 2008 R2, please install

Otherwise, we recommend you to install

Example of usage

Emit an event

Client:

var client = new SocketIO("http://localhost:11000/");
client.On("hi", response =>
{
    string text = response.GetValue<string>();
});
client.OnConnected += async (sender, e) =>
{
    await client.EmitAsync("hi", ".net core");
};
await client.ConnectAsync();

Server:

socket.on("hi", name => {
    socket.emit("hi", `hi ${name}, You are connected to the server`);
});

Emit with Ack

Client:

var client = new SocketIO("http://localhost:11000/");
client.OnConnected += async (sender, e) =>
{
    await client.EmitAsync("ack", response =>
    {
        result = response.GetValue();
    }, ".net core");
};
await client.ConnectAsync();

Server:

socket.on("ack", (name, fn) => {
    fn({
        result: true,
        message: `ack(${name})`
    });
});

Emit with Binary

Client:

var client = new SocketIO("http://localhost:11000/");
client.OnConnected += async (sender, e) =>
{
    await client.EmitAsync("bytes", name, new
    {
        source = "client001",
        bytes = Encoding.UTF8.GetBytes(".net core")
    });
};

client.On("bytes", response =>
{
    var result = response.GetValue<ByteResponse>();
});

await client.ConnectAsync();

class ByteResponse
{
    public string ClientSource { get; set; }

    public string Source { get; set; }

    [JsonProperty("bytes")]
    public byte[] Buffer { get; set; }
}

Server:

socket.on("bytes", (name, data) => {
    const bytes = Buffer.from(data.bytes.toString() + " - server - " + name, "utf-8");
    socket.emit("bytes", {
        clientSource: data.source,
        source: "server",
        bytes
    });
});

Get multiple response values

Client:

var client = new SocketIO("http://localhost:11000/");
client.OnConnected += async (sender, e) =>
{
    await client.EmitAsync("change", new
    {
        code = 200,
        message = "val1"
    }, "val2");
};
client.On("change", response =>
{
    // You can get the JSON string of the response by calling response.ToString()
    // After that you can decide how to parse the response data.
    // For example: ["val2", { "code": 200, "message": "val1" }]
    string resVal1 = response.GetValue<string>();
    ChangeResponse resVal2 = response.GetValue<ChangeResponse>(1);

    // If you don't want to create a model, you can parse it like this
    string message = response.GetValue(1).Value<string>("message");
    int code = response.GetValue(1).Value<int>("code");

    // More specific usage: https://github.com/jamesnk/newtonsoft.json
});
await client.ConnectAsync();

class ChangeResponse
{
    public int Code { get; set; }
    public string Message { get; set; }
}

Server:

socket.on("change", (val1, val2) => {
    socket.emit("change", val2, val1);
})
