OnClosed not working about socket.io-client-csharp

[doghappy]

If the connection is disconnected by the server, the OnClosed event will be called and the parameter value is ClosedByServer. If the server process exits, the OnClosed event will be called too and the parameter value is Aborted.

According to your description, I can't reproduce it. I would be very grateful if you can help me with it.

I used the code to test it and the test results were successful.

server

io.on('connection', client => {
    client.on('close', data => {
        if (data === "close") {
            client.disconnect();
        }
    });
    client.on('disconnect', () => {
        console.log(`disconnect: ${client.id}`);
    });
});
console.log('Socket IO server started');

client

static async Task Main(string[] args)
{
    var client = new SocketIO("http://localhost:3000");
    client.OnClosed += reason => Console.WriteLine(reason);
    client.OnConnected += () =>
    {
        Console.WriteLine("Connected");
    };

    await client.ConnectAsync();
    await Task.Delay(1000);
    await client.EmitAsync("close", "close");
    Console.ReadLine();
}

result

Yes, I test your code and it's work. but what if my server gets down? how your implementation can handle it and client understand the connection is lost and the server is not available after connection?

[doghappy]

In general, if the connection is closed by server, the server will return a specific code number(reason = ClosedByServer). But there is still a thread that polls for server status(reason = Aborted)

Right, I tested in a console application and it's work. I think it has a problem when running in unity. in unity, can't get the "Aborted" message

@farzadi Can you share your sample code for connecting to unity? We are having a difficult time setting that up.
