英文:
Connecting to socket.io using C# client, but using/joining room
问题
我正在使用 Node 和 React，使用 socket.io 创建房间没有任何问题。
在我的服务器端，我有以下代码段：
socket.on('connection', socket => {
console.log('user connected');
let room = socket.handshake['query']['r_var'];
socket.join(room);
console.log('user joined room #' + room);
});
这是我从客户端连接的方式：
import openSocket from 'socket.io-client';
openSocket(`${readerUrl}:${wsPort}`, {
query: 'r_var=dynamic_room'
})
我需要在 C# 中实现相同的功能，尽管我找到了一些 C# 的示例，但没有一个使用房间。有人有示例吗？
非常感谢！
英文:
I'm using socket.io with rooms without any problem with Node and React.
In my server side, I've this piece if code:
socket.on('connection', socket => {
console.log('user connected');
let room = socket.handshake['query']['r_var'];
socket.join(room);
console.log('user joined room #' + room);
});
And this is how I connecting from client side:
import openSocket from 'socket.io-client';
openSocket(`${readerUrl}:${wsPort}`, {
query: 'r_var=dynamic_room'
})
I need to do the same, but with C#. Although I found several examples for C#, none uses rooms. Anybody have some example?
Thanks so much!

我自己解决了问题，并分享解决方案，供需要的人使用。
使用的包是https://github.com/Quobject/SocketIoClientDotNet。它已经过时，但功能非常好，而且经常更新。
要传递查询（用于加入socket.io房间），需要使用类型为“Dictionary”的变量。
var query = new Dictionary<string, string>();
query.Add("room", "test");
var options = new IO.Options();
options.Query = query;
var Socket = IO.Socket("http://xxx.xxx.xxx.xxx:3001", options);
如你所见，我不是C#程序员，可能可以改进代码。

I solved it myself and I share the solution for who need it too.
The used package was https://github.com/Quobject/SocketIoClientDotNet. It's deprecated but work very well and it's pretty updated.
To pass a query (used to join rooms on socket.io), you need to use a var of type "Dictionary".
var query = new Dictionary<string, string>();
query.Add("room", "test");
var options = new IO.Options();
options.Query = query;
var Socket = IO.Socket("http://xxx.xxx.xxx.xxx:3001", options);
As you can see I'm not C# programmer, it's probably that you can improve the code.
