Connecting to websocket using C# (I can connect using JavaScript, but C# gives Status code 200 error)

Question

I am new in the area of websocket.

I can connect to websocket server using JavaScript using this code:

var webSocket = new WebSocket(url);

Answer 1

Since WebsocketSharp is not .NET Core compatible I suggest using this library. Here's some sample code

static async Task Main(string[] args)
{
    var url = new Uri("wss://echo.websocket.org");
    var exitEvent = new ManualResetEvent(false);

    using (var client = new WebsocketClient(url))
    {
        client.MessageReceived.Subscribe(msg => Console.WriteLine($"Message: {msg}"));
        await client.Start();

        await client.Send("Echo");

        exitEvent.WaitOne();
    }

    Console.ReadLine();
}

Be sure to use ManualResetEvent. Otherwise it doesn't work.
