How to connect to server via Socket.IO in C#?

Question

C++ / C#

There is a need to transfer this code to C #

var socket = io("socket.donationalerts.ru:3001");
    socket.emit('add-user', {token: "my-token", type: "minor"});
    socket.on('donation', function(msg){
        console.log(msg);
});

This is where the response in jsone comes in.
I am making a test console application to understand what goes where and how:
Connected SocketIoClientDotNet .

var socket = IO.Socket("http://socket.donationalerts.ru:3001/");

socket.On(Socket.EVENT_CONNECT, () => {
    socket.Emit("donation");
});

socket.On("donation", (data) =>
{
    Console.WriteLine(data.ToString());
    socket.Disconnect();
});
Console.ReadLine();

This code outputs to the console
DoWrite data = System.Byte[]
Well, and there are no add-user parameters in it. Actually the question can someone tell me how to transfer them there. And in general, in which direction to dig, I will be very grateful.

I believe in C# just a low-level response comes - an array of bytes.
It must be converted to a string:
var str = Encoding.UTF8.GetString(data);

Only you would like to know what encoding is used. I assumed UTF-8
